I know, we have written about the before, but its the number one thing we receive emails about, and everyone wants more clarification. So, here you go. As you know, epoxy concrete paint is a popular product for treating concrete floors. Epoxy, itself, is twice as strong as concrete, waterproof, and seamless. Additionally, its strength, durability, and beauty make it an ideal resurfacing choice in garages and basements.
What makes this system unique is that it is a two-part coating that cures on the concrete through a chemical reaction. The product is spread on the surface in a thick coating so that minor imperfections in the surface are covered up to leave a glossy, hard finish. Larger problems such as cracks in the concrete must be repaired or the epoxy will not adhere and the crack will reappear.
Epoxy will not stick if a vapor barrier was not installed when the slab was poured. Any moisture that moves to the surface of the concrete will make the epoxy concrete paint peel away, flake or blister. You can test your slab for moisture by securely taping a 12 inch by 12 inch section of concrete with plastic for 24 hours. Condensation will appear if there is a problem with moisture. The best time to check for moisture is after a recent rain.
Proper surface preparation is the key to getting good results when applying epoxy concrete paint. You can’t clean the surface too much. You will need to first clean and degrease several times and then acid etch the surface. You then neutralize the surface with baking soda dissolved in water and follow up with a thorough rinse with clean water. Allow the floor to dry for at least 12 hours before applying the epoxy concrete paint.
There are two different considerations when choosing a product. If low price is your highest priority then you will want to choose a solvent epoxy. This is a good choice for the novice because this type of epoxy gives you more time to apply it before becoming hardened. Solvent-free epoxies cost more and harden quickly. A professional can give you the best advice possible on which product is right for you.
Safety gear essential for the job are a high grade breathing mask, gloves, goggles and rubber boots. Safety instructions are included with the product.
A concrete floor treated with an epoxy concrete paint adds an endurable beauty that is well worth the time and money.
