Can PERMA·CRETE® be used to fill wide cracks that are the same depth as a concrete slab?
ANSWER:
If a crack is wider than 3/8" and through the slab, fill the crack from the bottom of the slab to within
1" of the surface with PERMA·CRETE® Matrix Mixture prior to repairing the crack. If the crack is 1/8" or 3/8" wide, fill the entire crack from the top to the
bottom of the slab with Perma·Bond and coarse sand.
QUESTION:
Can Perma·Seal Stain Sealer be applied over solvent-base Concrete Clear Sealer?
ANSWER:
Concrete Clear Sealer is a solvent-base sealer that dries to a clear, abrasion resistant film. Since
Perma·Seal Stain Sealer is a water-base sealer, it cannot penetrate or adhere properly to the solvent-base sealer and may later delaminate from the previous
concrete sealer surface.
QUESTION:
