· To provide uniform absorption in cementations or gypsum surfaces.
COVERAGE / CONSUMPTION
Preparation of substrate
The substrate should be dry, clean, and free from grease, oils, residual paint, and other loose material. In each case, the manufacturer’s recommendations for gypsum-plaster must be followed, particularly as far as moisture content and level of surface finishing are concerned. Cracks in concrete surfaces must be repaired with Epoinject. Anhydrite surfaces must be sandpapered.
