SikaCem®-101 Cureseal H2O may be applied using a roller, hand pump sprayer, or an airless sprayer. If using a roller, a non-shed roller with 1/4-1/2 in. (6.4-12.7 mm) nap length is recommended. The nap length of the roller will depend on the surface porosity and texture of the concrete.
When using a sprayer, apply material with a fan pattern nozzle. Maintain a wet edge and avoid excessive overlaps of material. Care must be taken to protect adjacent areas from overspray.
When used as a cure coat or as an initial seal coat, if additional protection or gloss is required, an additional coat may be applied 12-24 hours after the cure coat or seal coat has dried.
New Concrete: Uncolored, Integrally Colored, Color Hardened
Apply SikaCem®-101 Cureseal H2O immediately following final finishing and after the slab is firm enough to walk on without damage. Do not apply if bleed water is present. Apply to vertical surfaces immediately following form removal. Avoid runs or puddles and over application. To achieve maximum sealing and dust-proofing benefits, a second application should be made a minimum of two weeks after the initial application. Surfaces to be retreated should be clean and dry. Apply in a continuous wet surface film.
New Stamped, Textured, or Stenciled Concrete
After concrete has been stamped or textured using SikaColor®-300 Antiquing Release or SikaColor®-340 SG Antiquing Release, thoroughly remove the residual release powder by washing and scrubbing. The concrete should be allowed to dry thoroughly before applying SikaCem®-101 Cureseal H2O.
Existing Concrete and Overlays
Adequately remove accumulations of grease, oil residue, incompatible curing or sealing compound residue, and other substances that would diminish adhesion. Wash surfaces thoroughly. Allow the surface and joints to adequately dry before applying SikaCem®-101 Cureseal H2O. Smooth troweled interior floors will require mechanical preparation to ensure proper penetration and adhesion. Surfaces that resist penetration and immediate darkening with water, is an indication that surface preparation is required. Rough, porous, and deeply textured surfaces will require multiple applications to ensure the formation of a protective film, without pinholes or holidays.
New Overlays
Interior floors and exterior hardscapes that have been resurfaced should be cured 12-24 hours after installation at 70°F (21.1°C) before applying SikaCem®-101 Cureseal H2O.
