Epoxy varnish for wood - scope, properties
To quickly and reliably protect any or surfaces, most often paints are used. But if you want to preserve the natural, natural pattern, as well as the texture of the wooden surface, an epoxy transparent varnish is required.
Such a composition helps to effectively protect the material from negative influences, and also emphasize the beauty of the wood texture.
Varnishes made on the basis of epoxy resin are used not only for wood, but also for concrete and other materials.
Protective varnish solutions based on epoxy resin are made from the resin itself, which is diluted in the required proportion with an organic solvent.
Most often, this type of varnish is two-component, and must be mixed with a special solvent before application. An epoxy varnish is suitable for application to wood floors, parquet, wood panels, and other surfaces. Moreover, a special epoxy based varnish for concrete surfaces can be found commercially. Almost all types of varnish mixture cannot be applied over any other paint and varnish material, therefore, old layers of coatings should be removed from the surface first.
So, lacquer products, which are made on the basis of epoxy resin, have excellent technical indicators and characteristics.
Moreover, such material has an affordable cost,
and also has the following advantages:
And now a little about the cons of the composition.
Despite the fact that there are many advantages of such a composition, the epoxy-based varnish has certain disadvantages,
which will be directly related to the composition and structure of the material:
Now let's talk about the direct use of the composition.
Since the composition of epoxy lacquer products contains one of the varieties of resin modifications, for example, ED-16 or ED-20, then the protective layer will turn out to be very strong and also durable.Due to this quality, varnish is very often used for concrete, windows, parquet, furniture, doors, wooden floors, metals and many other materials. Such a varnish composition is very often used for those places where it is required to create a surface with an incredibly large strength reserve, and for those places where the base will be subjected to great mechanical and physical stress.
Epoxy wood varnishes can be used not only for flooring, for example, wood or parquet, but also for concrete, the production of souvenir products, and even for putty compounds. Most types of metal can also be treated with epoxy varnish as a finishing material.
The most commonly used and popular coating material is polyurethane epoxy, and it is this variety that helps to create a layer that is resistant to corrosion , damage, and other negative influences. This composition of varnish for concrete, wood and metal has polyurethane additives. The protective coating can withstand an incredibly wide temperature range, and we are talking about the interval from -200 degrees to +120 degrees.
The special components that make up the solution will isolate the base from moisture, repel dirt and various liquids. The protective layer has excellent strength, is able to withstand huge mechanical loads and electrical stress, as well as vibration.
Elakor-ELD is one of the most durable and wear-resistant epoxy-based varnishes for floor coverings. This compound can be easily and quickly applied to concrete, wood or parquet floors. After a day, the surface gains strength, becomes airtight and even resistant to wear.
The completely dried product is resistant to various petroleum products, acids and alkalis, and therefore it can be applied to floors not just at home, but also in factories, factories and even production workshops.
This varnish is used for the following purposes:
Next, let's look at how to prepare the surface before applying the varnish.
Before how to start the varnishing process, it is imperative to prepare the base. The preparation will include the following procedures:
- Remove any type of dirt, this includes debris, dirt, grease stains, dust, old paint and varnish material, peeling particles of the old coating.
- If varnish is to be applied to a metal surface, remove the rust by hand sanding or power tooling.
- If you plan to use wood varnish, the wood surface should be sanded and primed.
- Before proceeding with the treatment of the concrete structure, all cracks must be repaired and the base leveled.
- Products made of plastic should be matted with standard abrasive paper, and then degreased with solvent or alcohol.
If the mixture is of a two-component type, then it must be properly prepared before application. A hardener should be added to the base, and then the mixture should be thoroughly mixed for 5-10 minutes. Then it is worth waiting a couple more minutes for the chemical reaction to complete, at which time some types of varnishes become slightly whitish.
After all air bubbles have come out, you can start applying the solution. It should immediately be remembered that epoxy-polyurethane varnishes have a certain pot life, and usually it is from 1 to 2 hours. During this time, you should have time to apply all the prepared and diluted mixture. If you need to varnish large surfaces, then prepare the solution in portions. Stir the prepared composition every 20 minutes.
Procedure for applying a two-component epoxy varnish to parquet or concrete can be done with a spray gun or manually - with a roller or brush. The varnish composition should be applied at temperatures from +5 to +30 degrees, and the air humidity should be less than 80%. In no case should there be dew or condensation on the surface of the treatment, and it should not be allowed that the surface temperature is lower than +5 degrees. The varnish usually dries out after 8-13 hours, and complete polymerization occurs after about 48 hours, if the air temperature is about +20 to +25 degrees.
The best way to apply is, of course, a spray gun, but if you don't have a spray gun, wide rollers can be used.
Please note that the wider the roller width, the wider the beam, as the varnishing process will be easier and faster. When applying the composition to concrete or a parquet floor surface, do not pass twice over the same place, and due to this, the coating will be the same in thickness and uniform. If varnishing is done with a roller, then ideally it is worth doing a cruciform movement. Due to the lateral movements, the varnish will be applied to the floor, and the longitudinal movements will smooth the applied solution. Reduce the application speed near walls and columns, as well as other obstacles.
Before starting varnishing, roll out the roller.
When processing parquet, concrete or wooden floor with varnish, you should definitely follow these simple recommendations from the masters of their craft:
- Varnish preferably in several layers, and ideally it should be applied at least 3 times. The number of coatings will largely depend on how intensively the room will be used, what loads the varnish can withstand, and what characteristics of the surface to be treated.
- Slightly sand the surface before applying the topcoat.
- It is imperative to adhere to the same consumption over the entire area of the processing surface, this is approximately 0.
12 kg per square meter, and if the consumption is less, the varnished layer will be fragile; if the consumption turns out to be stronger, then the varnish will wrinkle.
- The varnishing process should be carried out in a respirator that has a special insert that is capable of absorbing organic vapors. During the drying process, epoxy varnish is capable of emitting toxic and harmful vapors for human health, and it is from them that the respiratory organs should be protected.
If you follow these tips, the lacquered coating will be durable and strong. Outwardly, it will look beautiful, shiny, and will reliably protect the treated base for many years.
