Customer Questions & Answers

Can this be used on concrete sub floor?

Asked by: Docs Glass Service Inc
Yes, SikaBond-T21 can generally be used without priming on properly prepared, structurally sound concrete, cement floors, chipboards, ceramic tiles, plywood and hardwood. All concrete, cement screed and gypsum based subfloors must be structurally sound, clean, dry, smooth, free of voids, projections, loose materials, oil, grease, sealers and other surface contaminants.
