Flexible cement exterior wall cladding for EIFS and one-coat stucco
TESS Thinset Exterior Surfacing System is a high-performance wall system for EIFS or one-coat stucco installations. TESS improves these cladding systems by replacing the synthetic stucco finishes with a naturally breathable, flexible, thinsetting Portland cement stucco finish that has been formulated specifically to repel water and resist dirt-pick-up while eliminating moisture entrapment issues associated with acrylic finishes. TESS component products include:
TESS Finish — Newly formulated, Portland cement-based exterior finish is the only flexible cement finish designed for both EIFS and stucco applications. TESS Finish provides the durability and colorfastness of a genuine cement finish, yet withstands substrate movement and vibration. This high-performance cladding repels water and dirt, resists UV fading, incorporates a 10 year non-leaching antimicrobial agent and contains absolutely no VOCs or harmful solvents whatsoever.
TESS Primer — Seals TESS One Coat Stucco or other masonry walls to prevent efflorescence and ensure color uniformity in the finish coat.
TESS Base Coat — A high performance, polymer-modified Portland cement base coat for use with TESS Finish in an EIFS installation. A fast-setting “cold weather” (CW) base coat is also available.
TESS One Coat Stucco — A strong, durable, climate-resistant cladding for buildings that applies faster and easier than traditional 3-coat stucco. It is available in either pre-sanded or concentrated (unsanded) form.
TESS Additive and Bonding Agent (TABA) — Enhances the performance, handling characteristics and curing of the TESS One Coat Stucco.
TESS Weather Barrier — Imparts a seamless protective barrier over the substrate and all substrate openings.
TESS products meet or exceed ICC-ES AC235 Acceptance Criteria for EIFS Clad Drainage Wall Assemblies and ICC-ES AC11 Acceptance Criteria for Cementitious Exterior Wall Coatings.
