Boss Surface Finisher – 20L

SKU: ASF20 Category:



Boss Surface Finisher is a non-film-forming sodium silicate solution designed to penetrate and densify concrete surfaces providing permanent case hardening and dustproofing. Densifiers can also be used to treat lightly rain-damaged slabs. Boss Surface finisher penetrates the surface and reacts with the free lime, bonding and strengthening the structure of the concrete.
Due to its high silicate content, surfaces treated with Boss Surface Finisher also develop an attractive sheen aiding in appearance, cleanability and dustproofing. Boss Surface Finisher is commonly used to treat large warehouse floors, retail floors and multi-level carparks.
Being a “surface treatment,” Boss Surface Finsher will not wear off and never needs to be reapplied making it the perfect, long-lasting surface treatment.
