Dr. Fixit 105 is an integral, cement-based powder waterproofing compound. Unlike surface coatings, this is a mix-in additive designed to be incorporated directly into cement during the preparation of mortar or concrete. It works by filling the microscopic pores within the cement matrix, creating a dense, water-repellent structure from the inside out.
Technical Highlights
Integral Protection: Because it is mixed into the material, the waterproofing becomes a permanent part of the structure rather than just a layer on top.
Anti-Efflorescence: It effectively prevents the formation of white "salty" deposits on walls, which are often caused by moisture reacting with minerals in the bricks or cement.
Shrinkage Control: It helps reduce the formation of hairline cracks during the drying (curing) process of plaster and concrete.
