Fresh concrete surfaces must be free of bleed water and have sufficient strength to withstand finishing operations. Hardened or old concrete must be prepared by high pressure jet wash or abrasive blast cleaning. All dust, loose and friable material must be completely removed from all surfaces. After mixing with a low speed electric stirrer, Sikafloor ProSeal can be applied in a continuous, even film by low pressure spray. Application is also possible by brush or roller. Please see the Sikafloor ProSeal Product Data Sheet for more information.
