Q: What is the best method to apply sealer to a concrete countertop?
A: Various methods are used to apply sealer to a concrete countertop, and it’s always a good idea to refer to the manufacturer’s recommendations for your specific product. Generally speaking, you have the choice of rollers, brushes, HVLP sprayers and lamb’s wool applicators. Many professionals apply the sealer with a 1/4-in. roller nap. Note that roller naps can leave lint on the countertop surface, so it’s a good idea wrap tape over the nap to remove loose fibers before applying the sealer. Remaining lint fibers can be removed from the countertop surface with light sanding.
