Protekta Micro-Emulsion can be used for the waterproofing of external brick walls and exteriors without leaving any patch. When Protekta Micro Emulsion is incorporated into low slump cementitious products such as imitation stone blocks and pavers, the permeability to water and the occurrence of unsightly efflorescence is dramatically reduced. It is an ideal solution to leaking Bathrooms and Toilets. Simply brush or spray on tiles and grouts.
