CEMENT BASED (SULFATE-RESISTANT) DRY READY MIX PLASTER weberpremix SP-7 is a sulfate-resistant cementitious ready mix plaster used for traditional plastering works in a clean and speedy manner, while keeping a homogeneous mix. Due to its high content in additives and fibers, it allows better shrinkage control as well as improved workability and curing. weberpremix SP-7 is recommended for external and internal plastering on block walls, ceilings, concrete surfaces, bricks and for general filling up. weberpremix SP-7 can be applied traditionally by hand or by using modern plaster-spraying machines. It should not be used on painted surfaces or floors. For the application on light weight concrete blocks, it is recommended to use weberpremix SP-3 FL.
