Rapid Filler and Grout

Remmers Sulfatex Rapid Filler is a high quality, mineral, fast setting, dry-mix mortar based on the newest technology. Substrate repairs and building waterproofing can be executed in just one day from just one bag!

Developed from the rapid setting Sulfatex Grout, Sulfatex Rapid Filler has unique properties only found in this product.
