Gel treatment: MetaClear
MetaClear is a non penetrating gel formulated for removing black discolouration from render and masonry without impregnation. Brush on and rinse, the gel is fast acting and low odour.
It is usually used before or after the AlgoClear treatment. If the surface is too contaminated, it is preferable to open the pores first and soak the render after
In many other instances, the AlgoClear treatment is carried out first and the remaining marks either left to recede naturally, or removed with MetaClear.
MetaClear lubricates the brush and limits the risk of surface abrasion. The detergency is achieved through the action of sodium hypochlorite and the sequestration of impurities in the gel.
