RadonSeal can be applied to bare and porous concrete. RadonSeal penetrates deep into concrete, reacts, and expands to fill the capillaries inside concrete. RadonSeal is not a topical sealant or coating system however. It does not seal water penetration due to structural defects, cracks, seams, corner joints, holes, and similar which may require caulking, patching, or other repairs.
The paperwork indicated it should be dry so it can absorb. Possibly use a box fan to dry it out a little? This product has worked great so far for me, I put on several coats, allowing it to dry between coats. Super easy to apply.
Yes, this is sufficient for sealing an cement ceiling.
RadonSeal should not be applied to a painted surface. Concrete surfaces must be completely bare, clean, and thoroughly dry before application. The leak you are describing is a cove joint leak (water penetrating between the wall and floor). Sealers do not always seal cove joints. You would need to repair the cover joint using a joint filler like our ElastiPoxy Joint & Crack Filler Kit.
It did not change the color of my cement. It does give it a tiny bit of a different sheen, but no color change.
RadonSeal is for cement based substrates only...poured concrete, concrete blocks, etc.. You should be using LastiSeal Brick and Masonry Sealer for your clay bricks (also available from Home Depot)
Yes, it looks like water but when it dries it’s a whiteish color, I spilled some on the floor and it dried.
Hello Cesar, Unfortunately, RadonSeal cannot penetrate through paint. The walls would need to be bare, porous, and dry. - RadonSeal
If applied properly it can be painted over after it's fully cured. However, any spots where it was over applied (will appear as a white patch on the wall) will not bind with paints unless physically remedied beforehand (sanding, grinding, etc).
Hello Bunny, Unfortunately, LastiSeal cannot fill gaps between block that do not have a mortared joint. LastiSeal seals the pores and capillaries in masonry units. it does not span gaps or act as a joint filler.
