Provides a virtually invisible seal on masonry

Over the years, cracks tend to appear on walls, whether indoors or outdoors. Our 425 Struktur Acryl sealant is perfectly suited for the resulting repair work. Due to its rapid drying and excellent levelling properties when using a smoothing tool, the plasto-elastic material is extra-convenient to work with. Depending on the temperature, a surface skin forms after just one hour. Due to its special grain size, the sealant is particularly suitable for textured masonry surfaces such as roughcast or textured plaster – which, in turn, means perfect visual results.
