SC Foundation Coating is designed to waterproof the exterior surface of below grade concrete and masonry. SC FOUNDATION COATING closes the internal voids in the substrate, but still allows full breathablilty.



  • Waterproofs interior, exterior, above & below grade masonry & concrete surfaces.
  • Apply to concrete block, brick, stone, precast concrete or formed concrete.
  • Apply to both positive & negative side (when hydrostatic pressure is low & aesthetics are not important.

Surface Preparation: The surface must be structurally sound, clean, and free of dirt, release agents, efflorescence, curing compounds, laitance, and other contaminates. Remove form marks and other protrusions to prevent “show through”. Form a cove at the footer-wall intersection point and fill all broken corners of block and breaks in the surface. Repair all surface defects including cracks and voids with SC FOUNDATION COATING mixed to a mortar consistency. Cut back wires a minimum of 3/4” and repair with Spec Patch or Spec Plug.
Dampen the surface with clean water immediately before SC FOUNDATION COATING application.

Mixing: SC FOUNDATION COATING must be mechanically mixed using a slow speed motor and mixing blade to thoroughly disperse the ingredients. Mix for approximately three minutes. Do not over-mix the material.  Pour approximately one half of the required two gallons
into an empty, clean container and begin slow speed mixing. Slowly add SC FOUNDATION COATING and mixing admixture* (water or Acrylic Bonder) as needed to bring the mixture to a heavy, completely blended pancake batter consistency. Stop mixing and allow the mixture to ‘fatten” for ten minutes. Re-mix and, if necessary, add more mixing admixture to reduce batter consistency. *Note: To improve bonding & mechanical properties on concrete, masonry and for all trowel applications, prepare an acrylic admixture using 1 part Acrylic bonder and 3 parts potable water. For example two gallons of mixing admixture consists of two quarts of Acrylic Bonder blended
with six quarts of water. When using as a pointing mortar, the use of Acrylic Bonder admixture is recommended.

Application: Pre-dampen the substrate with clean, potable water before any application. All applications should carry down to and over the footer, forming a cove at the walls-footer intersection. Apply two uniform applications of SC Foundation Coating, each application at approximately 1- 2 lbs/yd2, allowing 24 hours between applications. Make sure both applications carry down to and over the footer, forming a 1-1/2” (38cm) cove at the junction of walls and footers  Hand Brush: Apply using a six inch cement masons brush. Load bristles and lay on a heavy coat using long, smooth horizontal strokes. Apply sufficient material to fill voids. Final strokes should all be
in one direction to produce an even texture and finish. Allow first coat to dry for 12 to 24 hours before applying a finish coat.

Push Broom: Use a five gallon pail or wide mount tub to hold product. Dip a ten inch, Tampico bristle push broom into product mix just enough to load the bristles. Apply a heavy coat using long, even horizontal strokes. Apply sufficient material to fill all voids. Lift the brush at the end of each stroke. Final strokes should all be in one direction to produce and even texture & finish. Do not over-brush. Allow the first
coat to dry for 12 to 24 hours before applying a finish coat. Spray: Use heavy duty spray equipment capable of spraying cement-based products or mastics. Trowel: The use of trowel applications is required in some severe water pressure situations.
