I recently sealed my concrete countertops with a lithium based sealer applied with a pump up sprayer. I feel that I obtained a good seal, however, in those areas where the sealer pooled, the countetop has a whitish haze, even though I used a squeegee to move the sealer out of the uneven areas before the sealer had dried. I felt like applying wax as my final step (to increase the shine and water beading) would improve this haze, and it did to some degree, but it keeps coming back. It looks almost like a hard water stain. When I wet the surface of the countertop, I can still see the depth of color from the acid stain I used, but it eventually dries back to a light hazy appearance. Do you have any suggestions for help? I considered using mineral oil before applying wax to deepen the color back to what it was before I apply wax, and I will definitely use a different method of applying the sealer on my last countertop (I will use a pad to spread the sealer and make sure there is zero pooling). I feel like I messed up my countertop at the very end after all my hard work. Help! Thank you for your advice. Rebecca
Applying densifiers to concrete in an even manner can be achieved by wiping off excess liquid with a disposable shop towel. This will prevent pooling and a cloudy appearance. The cloudy look is caused by crystals that are bound to the concrete and can be removed by a light sanding with very fine sandpaper. Sanding in one spot may cause an uneven look that may be unsightly. Try to burnish off the excess as gently as possible in a circular motion. You may need to feather the edges of the sanded area. If a sanded spot proves to be too much of a distraction, try a sanding of the entire concrete surface.
Please let Big Al know how this works!
