Application
Fresh concrete:
Surface must be free of bleed water and of sufficient strength to withstand finishing operations. The concrete must be prepared by suitable power or manual floating / tamping techniques.
Hardened / old concrete:
The substrate must be prepared by suitable mechanical preparation techniques such as high-pressure water jetting or abrasive blast cleaning. All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by brush and/or vacuum. If in doubt apply a test area first.
Sikafloor® ProSeal-90 is supplied ready for use. Stir thoroughly before use for a minimum of 2 minutes using a low speed electric stirrer (~300 rpm).
For fresh concrete, apply immediately after finishing techniques have been completed. Apply in a continuous even film by low-pressure spray unit. The suitability of spraying equipment must be confirmed by trials. Application also possible by brush or roller. To achieve the highest visual aesthetics and performance, a second coat is recommended. Wait for first coat to dry tack free before applying a second coat.
