XYPEX Concrete Waterproofing – Coating Application

XYPEX Crystalline Waterproofing coatings are available in two grades: Concentrate and Modified. Sold in powder form, they are mixed with water into a slurry mixture which is applied by spray or brush on clean, bare and wet concrete surfaces.

Xypex Concentrate

Xypex Concentrate is the most chemically active product within the Xypex Crystalline Waterproofing System. When mixed with water, this light grey powder is applied as a cementitious slurry coat to above-grade or below-grade concrete, either as a single coat or as the first of a two-coat application. It is also mixed in Dry-Pac form for sealing strips at construction joints, or for the repairing of cracks, faulty construction joints and honeycombs. Xypex prevents the penetration of water and other liquids from any direction by causing a catalytic reaction that produces a non-soluble crystalline formation within the pores and capillary tracts of concrete and cement-based materials.

Xypex Modified

Xypex Modified can be applied as a second coat to reinforce Xypex Concentrate, or applied by itself to dampproof the exterior of foundation walls. Applied as a second coat, Xypex Modified chemically reinforces Xypex Concentrate where two coats are required and produces a harder finish. Where dampproofing is required, a single coat of Modified may be used as an alternative to a spray/tar emulsion. Xypex prevents the penetration of water and other liquids from any direction by causing a catalytic reaction that produces a non-soluble crystalline formation within the pores and capillary tracts of concrete and cement-based materials.

Coverage

For normal surface conditions, the coverage rate for each Xypex coat is 1.25 - 1.5 lb./sq. yd. (0.65 - 0.8 kg/m2).

Packaging

XYPEX Crystalline Coating products are packaged in 20 lb pails, 50 lb bags and 60 lb pails.
