To lubricate or not - that is the question.

For many manufacturers of small-piece concrete, including paving slabs, the issue of lubricating molds for better separation of finished products and reducing the amount of waste during formwork is urgent. As you know, release agents are always used in the production of large reinforced concrete products. But often, in the production of such products, decorative properties are not as important as in the production of paving and, even more so, facing tiles. In turn, it should be noted that careless attitude to the release agent and the process of its application can lead to loss of presentation and damage to decorative products. How to do it - you ask. Let's try to understand the process of lubricating molds.

So, lubricant is used to prevent concrete from sticking and form contamination - this is understandable. The lubrication process can be done manually - with a brush. Or you can spray a release agent, for example, with a spray gun or spray gun. The molds are lubricated immediately before the concrete is formed, each mold is lubricated separately.

Experience shows that it can be improved production process and without lubrication, but this entails an increased load on the mold and more frequent washing. For example, the Noria company has been producing paving stones using the injection molding method since 2001. During its entire existence, the mold lubrication process was introduced for only one season. Various lubricants of domestic and imported production were used. The lubricant was applied manually and later with a spray gun. But the result did not suit the production manager - with an increase in production volumes of paving stones (Antique No. 2, 52 pcs./m2), the lubrication operators could not cope with the process. Imagine, production reaches 130 - 150 m2 per shift, and if there are 52 pieces in 1 m2, then the lubrication section must process more than 6000 pieces. forms per shift. Errors by the lubrication operator lead to an increase in scrap, plus the cost of labor and materials increases the cost. As a result, this enterprise has improved the mold washing area and the concrete composition (now the composition is strictly controlled by the w/c ratio - the “harder” the solution, the less it sticks to the formwork). And it has successfully existed without lubrication for more than 10 years.

Today there are many domestic and imported lubricants on the market. Let's consider several options:

Emulsol.

Emulsol is a modern water-based lubricant, easy to use and inexpensive. It consists of biodegradable substances, which eliminates the adhesion of concrete to the surface of the form. Lubricants of this type are made from environmentally friendly substances; they do not require special measures safety when working with them. When applied evenly thin layer lubricants significantly reduce the adhesion between the concrete and the mold, the porosity of the surface of the products, and do not leave stains, which allows you to obtain products with a smooth and clean surface without subsequent finishing or grouting.

Emulsol prepared in a ratio of 1/3 to 1/5 with water. It is applied to each form with a brush or by spraying, carefully coating the corners and edges of the front surface of the form. In conditions high level pH in water, you can add soda ash to the solution (2% of the emulsol mass fraction).

It is worth stirring the solution thoroughly, although the lubricant dissolves well in water. Emulsol can be used not only for plastic molds, but also for metal ones. It perfectly protects metal from corrosion. It is not recommended to prepare the emulsion for more than one shift.

FREM SLAE - III

New generation anti-adhesive lubricant for molds and formworks, based on animal fats and surfactants.

When applied to cold and hot molds and during heat treatment, it does not decompose and does not release into the air. production premises products with a strong odor or harmful effects on humans and the environment.

Scope of application:

used in the production of prefabricated and monolithic concrete and reinforced concrete products and structures
effective both for molding products without heating and using heat and humidity treatment (HMT).

The main purpose of lubricants for metal molds is:

facilitating the separation of concrete from the mold or formwork material
security good quality the outer surface of products by reducing the number of defects - tears, peeling, etc.
protection of metal forms from corrosion

Advantages:

absence of oil stains on the surface of products
reducing costs for final finishing concrete structures
does not leave marks, does not change the color and texture of the surface

The lubricant is a concentrate that should be diluted with water in a ratio of 1 part lubricant to 3-6 parts water. In this case, no water preparation is required.

Apply the lubricant to a dry surface free of concrete residues. Applying excess lubricant leads to a decrease in the quality of the concrete surface, waste of material and unnecessary increase in cost.

Lubricant consumption when applied to molds with a brush or brush is from 30 to 50 g/m2.

Lubricant for paving slab molds plays an important role in the production of tile products. Certainly, concrete mortar, dyes, plasticizers and the right technology directly determine the quality of future tile products. Good lubrication makes it easier to remove products from molds and maintain (or even improve) their appearance. Moreover, it prevents the appearance of pores on the front side of paving slabs and paving stones.

For high-quality styling tiles, it is necessary to carefully prepare the molds for its manufacture.

Before pouring concrete into molds, they must be thoroughly cleaned and lubricated. By the way, they are made from various materials and there are metal, plastic, polyurethane, wood (formwork).

High-quality lubricant does not affect the shape, does not change the color of the cast tile and does not have a destructive effect on it.

The choice is quite diverse: all kinds of emulsions, powder and soap solutions, mineral oil concentrates, etc.

Variety of mold release agents

To produce a small volume of tile coverings, you can contact the nearest service station and purchase lubricant for a nominal price or for free. For large volumes of tiles and paving stones, special domestic and foreign lubricants are used. We list the most popular and frequently used in the manufacture of paving slabs and paving stones:

At home, you can make lubricant based on motor oil.

KSF-1. Available in the form of a homogeneous paste, it is characterized by low consumption, ease of application, provides an even, smooth surface and does not leave colored spots on it. The lubricant is non-toxic, dissolves well in cold and warm water. It is used in the form of an emulsol - a 9-10% aqueous solution. You can lubricate the molds with any means at hand. Used for plastic, metal forms and formwork.
Kristal, based on light mineral oils, is an environmentally friendly product, has excellent anti-corrosion properties, and is used for metal and wooden forms. Apply with a brush or spray.
Nometal also protects metal forms from corrosion, cracks and pores.
Agate, used for any shape, is a very economical lubricant, allowing 1 liter to cover 35 square meters. m. surface, has many positive reviews.
Anti-adhesive concentrate Tiprom 90 based on silicones, which has water-repellent properties, is usually used for the production of large slabs in metal and polymer forms. Does not respond to temperature.
Emulsol, made on a mineral basis, is often used in construction to lubricate formwork. Consists of biodegradable substances. It is applied with a sponge or spray, is quite affordable and is very suitable for the manufacture of paving slabs, without requiring subsequent grouting or finishing.

Many lubricants are available in the form of concentrates. Concentrates differ in that you can get more of the finished product from them. To do this, add them to water and stir for 5 minutes.

How is lubricant applied and is it possible to save money on it?

For easy removal of paving stones, the mold must be lubricated.

Apply a thin layer of lubricant to each mold with a brush or spray, depending on the selected lubricant. Before application, as already mentioned, you need to thoroughly clean the molds of debris and dirt. They need to be lubricated immediately before pouring concrete. No special clothing is required to apply the lubricant. It is enough to wear gloves to protect your hands from contamination. If the spraying method is chosen, it is better to wear a respirator.

When applying with a brush, you need to ensure that all corners are treated and that the bristles do not remain in shape. Any little thing can ruin appearance tiles

It should be noted that lubricant not only improves the process of removing tiles, but also significantly extends the service life of the molds, reducing the load on them.

Now here is a recipe for a simple and cheap DIY lubricant. Take 50 g of motor oil and dilute it in 1.5 liters of water. Shake it up. This needs to be done for quite a long time. We test on the product. You can experiment with proportions. A greasy lubricant can create holes in the tiles or oil stains on the surface, and a weak lubricant will worsen the removal process.

Some tilers use a saline solution to rinse molds. Hydrochloric acid is diluted with water, and forms are lowered into a 7-10% solution. Then they don't lubricate.

Some people use soapy water. It is prepared from ordinary soap or dishwashing liquid. Naturally, the savings are obvious, and the slipping of the tiles out of the molds will also please you, but they remain very dirty after it.

To summarize, let us once again outline the three main functions of a release agent:

easier removal of products:
reducing labor costs for cleaning molds and formwork;
maintaining the quality of products and their appearance due to the fact that the concrete does not stick to the form and the tiles do not have to be “torn off”.

By saving on lubricant, you can lose much more on discarding. Even when producing tiles for their own needs, everyone wants them to be beautiful, strong and durable.

Paving slabs are used to lay paths in summer cottages and cottages, and paths in the garden. Neatly tiled paths give a well-groomed look to any country house. It is better to purchase the product in construction markets or make it yourself. For self-made You will need lubricant for paving slab molds. You can also prepare it yourself or purchase it from construction stores.

Various options

The tile covering is made of concrete and can have different structures:

universal;
rectangular;
arbitrary;
castle;
model.

There are two options for making the product - under pressure and casting. The first method is quite heavy, and the second can be used for self-production. The composition of the product is also varied:

cement with sand;
fired clay;
rubber;
plastic;
granite.

Most often, cement is used as the basis for the product. This is a durable material that is practically indeformable during prolonged use. All that remains is to find out how to lubricate the molds for paving slabs.

DIY recipe

Regardless of the type of tile product chosen, the process will require a lubricant. The recipe for lubricant for paving slab molds is as follows:

motor oil (50 g);
water (1.5 l.);
dilute the oil with water;
the mixture must be stirred very thoroughly;
Make sure that the composition is not too fatty, otherwise it will not work quality product;
a non-concentrated composition is also not suitable.

When the lubricant is ready, you can start cooking concrete mixture. You will need a concrete mixer. If a multi-colored option is needed, then add to the concrete mixture acrylic paints. You can also make the molds yourself, especially if you want something unusual. They are made from wooden blocks. Special stencils are sold for applying the design.

Lubricant properties

Lubricate the molds for production before pouring. Do-it-yourself lubricant for paving slab molds has the following properties:

high-quality composition does not spoil the color and shape;
there are no pores allowing air to pass through;
the composition can be diluted with water;
the finished tile can be removed from the mold without any problems;
a thin layer of composition is required;
no need to purchase special clothing.

The lubricant is applied with an ordinary sponge. The forms in which the products are prepared usually do not have heavy pollution. The lubricating solution does not require special skills or costs to prepare.

Types of lubricants

There are several types for lubricating molds with different properties:

Almost all mixtures are concentrated. This is good because you can prepare a lot of ready-made ingredients. Add water to the concentrate and mix thoroughly until a homogeneous consistency is obtained.

How to lubricate?

To get a quality product, you need to know how to coat molds for paving slabs. Be sure to clean the molds before starting work. There should be no debris or any contamination left in them.

Important: lubricant for paving slabs is applied only before pouring the concrete mixture. Apply the mixture to the walls in a thin layer. You can use a brush, sponge, spray. The tool depends on the composition of the lubricant. You will only need gloves to protect your hands.

Observe the following rules:

tile molds should be lubricated so that there are no gaps;
make sure that no brush bristles get into the molds;
You can clean the molds with a solution based on hydrochloric acid (diluted with water).

It’s easier to clean with soap and water. You need to mix the soap with any dishwashing detergent.

Thanks to the preliminary application of lubricant to the molds, we get the following result:

the product can be removed perfectly;
formwork and forms are easy to clean;
The original shape is preserved because it can be easily removed.

Lubricate the plastic

Grease for plastic molds of paving slabs is also applied before pouring. Each mold needs to be processed separately. The compositions do not require work in special clothing, thanks to environmentally friendly components.

Advantages lubricant composition based on biodegradable components:

safety at work;
economical;
mixes with water;
does not affect the rate of hardening of the concrete mixture.

Another advantage to using emulsol as a lubricant is frost resistance.

When diluting concentrates with water, make sure that the mixture is homogeneous. Silicone grease for paving slab forms it has good water-repellent properties. Most often it is used in the manufacture of large tiles. Can process plastic and metal molds.

Fill

The forms are greased, all that remains is to fill them concrete composition. The work requires compliance with certain rules:

It is better to use a vibrating table. Do not weaken, try not to overload the springs;
Large tiles are made in two steps. First, they fill it to the middle, then the reinforcement is placed. The final stage is complete filling.

When making products with your own hands, lubricant for paving slabs plays an important role. After finishing the work, the product literally jumps out of the mold without additional effort.

The secret of beautiful tiles

So that the paths and sidewalks are on summer cottage looked beautiful, you need to know how best to lubricate paving slab molds. Lubricating compounds make the entire tile production process much easier.

Thanks to the proper use of lubricants, the molds remain in working order. long time. Depending on the structure of the composition, it may be enough for a large number of molds. Preparing the mixture will take time, but will pay off in the process of making the tiles and subsequent cleaning of the molds. A properly prepared lubricant allows you to remove finished products from molds without deformation. Lubrication also affects the color of the product.

Follow the main rule: the molds are not filled with grease, but rather lubricated.

Let's compare the efficiency

Cheap, readily available components can also be used as lubricating solutions. Let's look at how they behave during operation:

Which composition will be better depends on the quantity of the product produced. Therefore, if sidewalk paths do not amount to several kilometers, then there is no need to spend extra money. Try homemade options for making lubricating solutions.

Regardless of what lubricant you use during the process, you should not leave finished products in the molds for a long time. The deadline when the product can be removed without problems is three days. If you leave it longer, it will be difficult to wash the molds.

How to avoid bubbles?

Lubricating mixtures help not only to safely remove the finished product. This way you can avoid the formation of bubbles on the surface of the tiles.

Bubbles usually form on the face of the tile. It looks very ugly. This is why it is so important to pre-apply a lubricant before pouring concrete.

To improve the quality and effect of the lubricant composition, add a plasticizer to it. This action will prevent the appearance of bubbles.

Cement affects the quality of tiles. The material must be fresh, not stale. Pay attention to the cost of cement, and it’s better not to save money. It is advisable to purchase cement in large construction stores, where you can check the contents of the material.

To give the tiles the required color, try to dilute the dyes in advance. It’s good if the diluted solution remains for half a day. Don’t be afraid to leave the dyes for so long, they won’t deteriorate and the structure won’t be deformed.

Starting to ennoble garden plot or the area around the house, we must not forget about the paths. Only they can give your site a complete and aesthetic appearance. If you decide to create paths from paving slabs, then you can do it yourself. You don't need to be an expert to handle this matter. Having learned all the nuances of the work, such as how and what the tiles are made of, how to lubricate the mold for paving slabs and how to lay them, you can confidently get to work.

Choosing the shape of the tiles is also an important matter; they are divided into several main types: rectangular, freeform, universal, model, castle and ecological shape.

Features: manufacturing and application

Paving stones are made from concrete, which in turn consists of cement, sand and water mixed in required proportions. Everything is taken into account here, from the brand of cement to the purpose and area of application of paving slabs.

What kind of pressure should it withstand and the like. Most often, cement is used either 1:3 or 1:4, for example, if cement is grade M 500 (which is considered one of the best), then the proportion will be 1:4.

Paving stones are made from concrete, which in turn consists of cement, sand and water mixed in the required proportions.

Choosing the shape of the tiles is also an important matter; they are divided into several main types:

rectangular;
arbitrary;
universal;
model;
castle;
and ecological form.

Tiles are also divided according to the production method, among them there are two main ones - cast and pressed.

To make pressed tiles you need special equipment and large investments, that is, it is very difficult to do this at home.

Such tiles are used for paving large areas and roads; they can withstand very high blood pressure, due to the fact that during production the concrete is constantly exposed to blows from a special hammer.

Available application options

This method is available to everyone and makes it possible to create a slab of exactly the shape and size that we need. In order to create it, you will need concrete.

When making it, you can use the “clumsy” method, mixing with a shovel in a trough. But this is a very labor-intensive process that takes a lot of time. It is better to use a concrete mixer that you can buy, rent or borrow. Do not forget to add a plasticizer to the mixture; if it is dry, then it must be dissolved in water.

And to get tiles various colors, acrylic paints are added to concrete, so you can create tiles not only of any shape, but also of any color. The paint must be mixed with sand before adding it to the mixture.

To obtain tiles of various colors, acrylic paints are added to concrete, so you can create tiles not only of any shape, but also of any color.

In addition to concrete, you will also need forms, which can be purchased in specialized stores; the most convenient are forms made of rubber and polymer. But you can also make them yourself.

For example, make frames from hewn wooden blocks. In this case, the shape will depend solely on your imagination and skillful hands. However, to create a drawing, you still have to go to the store to purchase a stencil to your liking. The stencil is applied to the concrete as soon as it is poured into the mold and removed after a few minutes.

What does the lubrication process involve?

But before you pour concrete into the finished mold, you need to lubricate it. The choice of lubricants is large enough so that you can choose exactly what suits you. These can be petroleum oil concentrates, emulsions, soap and powder solutions and other lubricants used in the manufacture of paving slabs.

A good lubricant should not change the color of the cast tile and should not affect the shape in any way. By the way, if you plan to create a very small amount of tiles, you can ask for it at a service station, and they will give it to you completely free of charge or for a symbolic price.

One of the most popular and frequently used is KSF-1 lubricant. Its advantages are low consumption, ease of application, using any means at hand, and in the end, everything results in a very reasonable price.

Krystal oils are very often used to lubricate molds for the paving system; more precisely, an emulsion is made on their basis, and it is applied using the spraying method.

Nometal lubricant is perfect if you use metal frame. It will protect it from corrosion.

Each lubricant, in addition to its individual properties (if any), must perform certain functions:

One of the most popular and frequently used is KSF-1 lubricant. Its advantages are low consumption and ease of application.

With its help, paving slabs are easily removed from the mold.
Thanks to the lubricant, pores do not appear on the front of the tile.
Appearance should only improve, but not change in color.

Only when these goals are achieved is the use of a lubricant considered appropriate, otherwise its use is pointless and is not worth the material costs and lost time.

A good economical option for lubrication is a lot famous series Agate, this remedy has long proven itself on the positive side.

It is used for absolutely all types of formwork, and one liter is enough for 35 sq.m. surfaces.

Release concentrate is also used as a release agent, typically for metal and polymer molds. It is most often used to create large slabs. When using it, know that it is water-repellent and does not react to temperature.

Do not forget that lubricants are highly soluble in water, which allows you to get about ten liters of ready-made mold processing product from one kilogram of concentrate.

You also don’t need to have any special skills for dilution, just add the concentrate to the water and mix for about 5 minutes.

No special clothing is required when lubricating the tiles. Ordinary work clothes are fine, since there are no harmful effects lubricants have no contraindications and are in complete harmony with the environment.

Lubricating the mold will not only make it easier for you to release the tiles from the mold, but will save you from having to wash the mold itself later.

In order for the tiles to turn out perfectly smooth and the installation process to be quite simple, before lubricating the mold must be cleaned of dirt, debris and small parts.

This is done with a 10% solution of hydrochloric acid.

By the way, you can find a replacement for lubricant, for example, use an antistatic agent instead. But if you use a lubricant, which is actually preferable to an antistatic agent, then do not forget that you need to apply it in a thin layer.

First, be sure to clean the mold from dirt, debris and small parts that can get there, even with the help of the wind. Only on a thoroughly cleaned form can you begin to grease with the prepared mixture or pollinate with it. It is better to do this with gloves, just so as not to get your hands dirty.

And of course, if you are not lubricating, but pollinating, then it is better to wear a respiratory mask. If you use a brush to apply the lubricant, make sure that no hairs from it remain inside the mold.

Any detail, even the smallest one, will definitely be imprinted on the surface of the tile, which, of course, will ruin its appearance and your mood. In general, using a lubricant will make your work easier and improve significantly.
