Stuc-O-Base is a wet-mix concentrate that when mixed 1:1 by weight with Portland Cement is used as an excellent adhesive and underlayment for use with acrylic finish coatings. Stuc-O-Base uses a high quality acrylic polymer that provides a strong bonding surface on several different types of foam as well as concrete substrates, creating a strong level platform for finish coat applications.
Stuc-O-Base should be mixed 1:1 by weight (equal parts) with fresh, dry Portland Cement type I or II. Product should be allowed to sit for 10 minutes, then remixed & used immediately. Avoid retempering after mixing the Stuc-O-Base. Application
Stuc-O-Base is usually applied with stainless steel masonry trowels at a nominal 1/16 -1/8 inch. It can also be spray applied with proper equipment onto the substrate, then troweled to smooth out the surface. Over approved foam substrates and the Waterway Drainable Stucco Assembly, Stuc-O-Base should be used in conjunction with fiberglass reinforcing mesh.
