heydecco — MicroTop Wall System
MicroTop Wall Ready-to-Use Kit
A streamlined, pre-measured microcement kit designed specifically for wall applications — primer, fine coat, toner, and 2-component sealer, all included.
MicroTop Wall RTU applies directly over smooth absorbent surfaces like plaster, drywall, paint, and tile — with no demolition required. Lighter and simpler than the floor kit: no base coat needed, same seamless result in 2 coats.
