How to Seal and Waterproof Cinderblock Using Cinderblock Sealers.

1. How To Seal and Waterproof Cinderblock

2. About Cinderblock
Cinderblock is very porous. Not only will it allow
water and moisture to pass through it, but it will
store water within the block.
Due to the amount and size of the pores, there
is only one sealer that can effectively waterproof
cinderblock.

3. Armor SX5000
The Armor SX5000 is a penetrating sealer that
chemically reacts to form a hydrophobic barrier
within the pores of the cinderblock. Designed
for porous substrates, the Armor SX5000 will
stop 100% of water and moisture and will last
for 10+ years when properly applied.
The Armor SX5000 works below the surface and
won’t change the look of the cinderblock.

4. How To Waterproof Cinderblock
1. Make sure the cinderblock is clean, free of
paints and other sealers.
2. Using a brush or roller, apply one coat of the
Armor SX5000 sealer. Make sure the
cinderblock is completely saturated – use this
sealer to seal the grout as well.
3. Apply a second coat of the SX5000 sealer.
4. Let dry.
