Epoxy Or Polyurethane: Which One Is The Best Coating For Your Garage Floor

The new polyurethane and epoxy floor coating offer tremendous advantages and can protect any floor against wear, oil, chemicals, damage and stains of various different kinds of materials. These long-lasting floor coating materials are also easy to maintain and can reflect light. When it comes to the coating of the garage floor, you may wonder which flooring would be best. Here is a brief description of the two coating materials.

Epoxy Coating

The thermosetting polymer Epoxy is available as solid, water or solvent based or as a garage floor sealer and coating. The epoxy adhesive coatings match the garage floor requirements better and a single coat may have a thickness varying from a minor of 3 mils to up-to 10 mils. The hundred per cent solid epoxy formulations offer a thick and hard coating surface that can resist impacts easily. The coating can also remove the imperfections of a floor as it can fill the small and the hairline cracks, and the thickness is self-levelling as well.  

Epoxy can resist degradation by a number of chemicals and elements, and the coats are mechanically strong. Epoxy resin has of two different components including hardness and resin. The hardener is dark coloured and smells like Ammonia, while the resin is light in weight and does not have any odour. The two components of epoxy are mixed prior to its application, and they combine to form a strong plastic material. Epoxies are also excellent adhesives, offer extreme resistance to heat and also possess insulating properties.

When applying the epoxy coating to the garage floor, ensure that the floor is entirely clean and does not have any oil stains, debris, dirt and other undesired substances. Before actually applying the epoxy coating to the floor, you will have to apply the primer, which is a specialised solution that will help the paint to stick to the garage floor. Use of primer is not necessary but is recommended for added durability.

Polyurethane Coating

Polyurethane is also kind of thermosetting polymer and its coatings that offer extreme performance in most adverse of situation. For garage coatings, the aliphatic polyurethane may be considered, which has up to 70% of solids. The thickness of this coating can be up to 3 mils, and it does not provide the extreme adhesion to the floor that epoxy can offer.

Polyurethane has greater flexibility and impact and wears resistance when compared to epoxy. Polyurethane is also more U.V. (ultraviolet rays) stable and does not turn to yellow (like epoxy does) when sunlight falls on it. Polyurethane coating is also available in varying finishes including glossy and satin finishes.

Epoxy offers the best performance dues to its excellent adhesion, and polyurethane lags here. The polyurethane coating may also not fill-in the cracks and gaps in the floor, and the thin film may not be adequate. The application of the polyurethane coating on the garage floor may also be more problematic and requires a “respirator”.

Which one is best for the garage floor?

Both the floor coating materials have their own benefits and hence a combination of the two may be used to get the best benefits for your garage floor. Floor thickness can be built by using the epoxy flooring, and on the top, a coat of polyurethane may be added for protection and finish. The floor may last better in the long run and the upper coating will make it resistant to scratches and the sunlight UV rays. Depending on the floor requirements, either of the two or the combined version can be used for better durability and protection.

The epoxy resin price is quite affordable and you can also purchase it online. Most of the leading suppliers can offer you the best coating materials at a reasonable cost.
