BETONI-PEITTAUSLIUOS Etching Liquid is an acidic, emulsifying washing liquid for etching concrete floors. BETONI-PEITTAUSLIUOS Etching Liquid is a quick and easy way to remove laitance from the surfaces to be painted.
BETONI-PEITTAUSLIUOS reacts with the alkali concrete laitance, which neutralizes the containing hydrochloric acid. The reaction will form water and salts, that can be rinsed off with water. BETONI-PEITTAUSLIUOS contains also an emulsifier that will add to the product´s cleaning ability. BETONI-PEITTAUSLIUOS and the following water rinse will remove from the concrete floor the laitance and the dirt, surface grease and chalk-salts that would hinder the painting. The product will not remove grease and oil that has absorbed into the pores, but they are to be removed e.g. by sanding or grinding. The product is not suited for washing previously painted surfaces. BETONI-PEITTAUSLIUOS is also suitable to use for cleaning brick, tile, stone and wooden surfaces from concrete and plaster remnants after plastering and grouting.
