Application steps

SUBSTRATE PREPARATION

The receiving surface must be clean, free of dust, dirt, oil, grease, loose stone, loose sand, deteriorating paint or other foreign materials which could impair bonding ability. Smooth surfaces shall be abraded before application. On porous surfaces, lightly dampen before applying SikaWall® Superhold.

Apply a test patch and allow to dry for 24 hours. If SikaWall® Superhold curls or cracks, the surface must be cleaned thoroughly prior to application.

APPLICATION

SikaWall® Superhold is ready to use. No mixing or stirring is needed. Do not dilute. It may be applied by hand with brush or roller, or spray applied using an airless sprayer delivering at least 2.8 kg/cm2 (40 psi), with an orifice size no smaller than 0.5 mm (0.02 inch). A larger orifice may be necessary. Spray approximately 46 cm (18 inches) from surface in a crisscross pattern. Apply new material to be bonded to SikaWall® Superhold within 72 hours of the application of SikaWall® Superhold.

For maximum adhesion of new cementitous materials, use SikaWall®-73 Adacryl Admix & Bonder as an admix (1 part SikaWall®-73 Adacryl Admix & Bonder to 3 parts water) plus SikaWall® Superhold (undiluted) on the substrate.

CLEANING OF TOOLS

Clean all tools and equipment with detergent and water immediately after use. Clean up spills, splatters and overspray before it is allowed to dry.
