Water penetration protection for wood & cementitious materials

PSC 4400 is a next-generation waterproofing coating for infrastructure materials. It is multiple component coating, designed to block about 99.0% of water entry through materials exposed to extreme water conditions. This ultimately achieves the goal of greatly extending the useful life, as well as the aesthetic of the infrastructure material.

PSC 4400 can be used as a waterproofing medium for basements, underpinnings, crawlspace walls, or any other areas where water is likely to accumulate.

  • Protects substrate from water penetration
  • Extends lifespan of infrastructure
  • Environmentally Friendly
    • Water-borne polymer with innovative core-shell technology
    • Low VOC
  • Applicator Friendly
    • Easy to store and apply by brush, roller, or low-pressure sprayer
    • Minimal PPE required
PSC 4400 is a state-of-the-art water-borne polymeric coating specifically designed for the reduction of water penetration. The water-based acrylate/styrene emulsion blend has self-crosslinking components, providing significant strength and durability to the infrastructure to which it is applied. The cross-linking begins at ambient temperatures and continues until a vast array of strong covalent linkages have developed.

CAUTION: Prior to use, please read the Manufacturer Warranty & Disclaimer.

PSC 4400 is a premixed, water based, ready for use product to be used as a coating for concrete (porous) infrastructures. Mix PSC 4400 very gently to make sure that the tint (if present) and consistency are uniform. Do not dilute PSC 4400.

Be sure to apply the coating when ambient temperatures and conditions are within the suggested parameters.

The theoretical coverage (for one coat) per gallon of PSC 4400 is determined to be approximately 250 square feet. The theoretical coverage for one coat is approximately 6.10 square meters per liter. This is dependent upon such factors as Wet Film Thickness (WFT), any wastage that might occur, and the applicatorʼs technique and method used and the porous surface to which it is applied.

The PSC 4400 can be applied with a brush, masonry nap roller, and/or a low-pressure sprayer using an adequate nozzle size. If a sprayer is used, do not allow the coating mixture to remain past its pot-life but clean immediately upon completion with copious amounts of soap and water.
