In this blog post we’re going to talk about the main floor paints, their advantages and disadvantages, as well as a comparison of the most used alternatives currently in the market for industrial environments, warehouses, industrial buildings, garages, workshops, food industry, refrigerating chambers, etc.
Epoxy paint and epoxy resin are terms that are very often confused and used indiscriminately. If you were to buy an epoxy paint to paint a floor or use as a coating, you may find these terms everywhere and not know that there are some differences between the two terms.
An epoxy coating is technically not a paint. On one hand it is part acrylic paint, which allows customizations in colour, but on the other hand it is composed by epoxy resin, which attributes resistance, brightness and other main characteristics to the mixture. It is often used in industrial floors, garages and workshops although it’s increasingly common to see it applied in domestic environments.
What is epoxy paint?
Epoxy coatings use a mixture of two separate components to coat your floor. Kits purchased at a hardware store or DIY stores will allow you to mix a part of epoxy resin with a polyamide catalyst.
Unlike epoxy paint, this mixture will cure rather than dry. A concrete floor will benefit from this hard curing because the process fills the porous concrete.
The resin provides shine to the flooring and an epoxy layer protects it from stains, leaks and scratches.
How to apply epoxy paint?
For large surfaces we recommend going to specialists, who even using all their experience can’t always assure a good result.
This depends on many factors, here we leave you a post for you to take into account before working with epoxy.
As a base for painting, concrete isn’t the best. It absorbs moisture from the soil or any surrounding filth, it breathes and it soaks up paint like a sponge.
Concrete requires special paints that contain binders that contract and expand along with the surface.
Don’t use homemade oil-based or acrylic paints on concrete or you’ll simply have to paint it all over again, because acrylic paints will peel and crack. They won’t be able to endure the wear and tear that these concrete floors, sidewalks and concrete surfaces are exposed to.
Two component epoxy floor coverings
If you want an extra strong floor paint for industrial buildings, garages, workshops, go for a two-component epoxy floor paint.
These paints sometimes include fragments of colourful aggregates that can be spread over wet paint and add colour and depth to the finished surface.
Hardware stores usually offer kits to paint concrete flooring, which usually have enough paint to cover an area of 15 to 20 square meters.
After mixing and adding the catalyst to the paint, the same way you would with resin, all of the mix should be used, because once it hardens, it can’t be spread.
Let it dry for a period of 24 hours before walking on it, and three days before driving over it.
Epoxy Terrazzo options
As a decorative option for an interior or exterior concrete floor, an epoxy terrazzo finish creates a mosaic type floor that includes small pieces of granite or marble embedded into the epoxy coating.
After the surface dries, the floor is polished by floor polisher. Terrazzo epoxy coatings have a thickness of 7 to 8 mm compared to traditional terrazzo which is 5 to 6 cm thick.
The new epoxy terrazzo also includes colour options and multiple types of aggregates such as synthetic materials, mother of pearl or recycled glass. With the artistic use of these epoxy terrazzo products we can create geometric shapes and designs, logos, artistic representations and contrasting edges.
Sealing and priming in just one step
It isn’t necessary to seal and prime separately when using a primer that can also seal concrete at the same time. Any cured concrete residue, oil or grease must be removed and thoroughly cleaned from the concrete surface as these can interfere with the adhesion of the primer or paint.
If you only plan to add a two-part epoxy coating, you don’t need to prime or seal the concrete; just make sure the surface is completely clean first.
Coloured dyes for concrete
When it comes to colouring concrete, the use of a colour dye works very well for exterior surfaces. There are water-based concrete dyes that become the permanent colour of the concrete surface, and there are also acid-based dyes that react with the surface and change its colour.
Water-based concrete dyes take less steps than acid stains and generally have more colour options to choose from. To prevent the colour from fading, add a sealant to the water-based stained concrete once it has dried.
Epoxy floor coverings are commonly used for commercial and industrial flooring. Epoxy coatings are normally applied on concrete floors to provide a high performance and smooth finish to its surface.
Many industrial centres, warehouses and commercial buildings rely on epoxy flooring to maintain clean and safe conditions for workers, equipment and stock.
