Deco 20 Seal is a 100% water-based acrylic membrane designed to waterproof and protect concrete foundation walls from hydrostatic water pressure. These can be, Poured, ICF, Precast, or Block (parged/non-parged) foundation walls.
*IMPORTANT*
Deco 20 Seal is environmentally safe, contains no harsh chemicals, and is safe to use. The majority of foundation products are labeled “water-based” solvents or “water-emulsified” tar. This is due to water being added to make these products appear “eco-friendly” and/or “safe” to apply, but in most cases need use of a respirator because even though water was added, it still contains harmful chemicals.

DECO 20 SEAL IS BUILT GREEN - AN ENVIRONMENTALLY ECO SAFE PRODUCT!!
Deco 20 SEAL Applications
Foundation Walls:
- CMU Block, Precast, Poured Concrete, ICF & Styrofoam Walls.
- Parged Block * (also known as a mortar scratch coat over CMU block)
- Open or Exposed Walls and Tapered Grade Lines. Esthetic Looking!
Preparation:
- Remove all dirt, dust, oils, foreign material which is to be coated.
- Fill or repair any cracks, honeycomb, wall ties, holes, etc. with Deco Tie Patch or concrete repair caulk/patch.
- New Construction - Surface must be dry to allow for proper adhesion. Can be applied on green concrete. The American Concrete institute (ACI) defines green concrete that has set but not appreciably hardened.
- Use 2000+ PSI airless sprayer w/ flow rate of 1-2 gallons per minute. Apply first coat w/ no run downs and if you can apply second coat at starting point and second coat holds w/ no run downs apply. Otherwise let first coat set until second coat can be applied.
- Roll On - Use 3/4" or 1" nap roller and apply on surface evenly but do not product run down or your applying to heavy. Apply one coat let dry then apply second coat.
- Protection Boards - Optional if grade is heavy clay, rocky/shale we recommend a pink/blue board. Apply liquid nails on board and place against the wall over Deco 20 Seal.
- Temperature of 32-95 degrees otherwise cold or evaporation will affect Deco 20 Seal dry/curing and/or coverage rate
- Do not apply with the threat of imminent rain. Perform test to insure desired results.
- Dry cure rate is 12 hours. Dependent on temperature, airflow, humidity. Do not backfill grade until Deco 20 Seal is dry.
* Specifications require Deco 20 Clear Sealer to be applied first on non-parged block walls only. Allow Deco 20 to dry then apply Deco Seal. Deco 20 is a primer and increases adhesion.
