Alongside ASO-Unigrund primers, the system also offers the smoothing compound SOLOPLAN-30-PLUS and the compatible levelling mortar SOLOCRET-60. Your solution to levelling walls and floors.<\/p>\n

As an accessory, the system is extended with the rapid hardening silicate-based casting resin ASODUR-GH-S. The product for effective sealing of cracks in the substrate. The substrate system from SCHOMBURG makes it simple for you to level substrates and prime the areas.<\/p>\n
