Fully matte and washable urethane alkyd-based barrier coating for renovating interior surfaces with soot, nicotine, water and other damaged areas. At least two layers reduce the risk of penetration of branches even on old wooden surfaces. Heavily “bleeding” branches may require resin-rite varnish or shellac. Blocka is also suitable for ceiling paint, especially for tightened ceilings and/or surfaces treated with adhesive paints.
