rebetop base

Rebetop Base is a projectable plaster developed for regularizing facades, walls, ceilings and walls, applicable in exterior and interior environments.
Recommended to promote regularization and flatness to surfaces, making them suitable for receiving thermal insulation boards or textured mortars (sanded or smooth), working perfectly in a double layer system.
Especially suitable for regularizing facades that will receive ETICS solutions. Endowed with high profitability, it allows maximizing resources on site, such as labor and equipment).
