Beeck Etching Fluid is a specialised acidic solution used to remove lime binder deposits from new mineral renders or sinter skin from existing renders. As part of the Beeck Mineral Paint system, it can be used as a preparatory or pre-treatment step before applying Beeck Renosil External Paint or Beeck Beeckosil External ASF Paint to achieve an improved chemical bond between the paint and render.

Free from solvents, biocides, and preservatives, this nearly colourless solution is concentrated and can be thinned with 3 to 5 parts clean potable water, depending on the application area and condition of the background substrate. Available in two sizes, 1L and 5L.

Please note that colours represented online are indicative. We recommend purchasing a sample pot and experiencing the paint first-hand before making a final selection.
