Does MAGNATILE require any sealer?
Sealers are often used on raw, porous substrates to prevent outgassing and excessive penetration of the top coat. I have seen a few older residential garage floors that had never been painted before, which drank up close to twice the amount of 100% solids material they normally would have required. There was so much air in the slab that large bubbles rose to the surface leaving craters as they broke which did not flow back together. The use if a sealer would have eliminated this problem. You can determine if this situation exists with a careful inspection of the surface. After acid etching, allow the surface to dry thoroughly for 48 hours. On the bone dry surface, gently sprinkle some clean water on the etched surface. Watch the water carefully. If the floor sucks up the water quickly, it would be a wise choice to use a sealer prior to coating with MAGNATILE. A sealer will penetrate the surface and displace the air that would normally cause problems with 100% solids material. Sealing i
