Proposed formwork board comprises deck and carcass in form of rectangular frame made of contour profile reinforced with transverse profiles. Deck is equipped as a whole with nano-modified epoxy anti-adhesion coating consisting of epoxy resin reinforced with amorphous nanosized silicon dioxide with particle size of 20-100 nm, with specific surface area of 95-400 m2/g, coating hardener and curing system, which is a mixture of stabilizer, water repellent and antioxidant. Deck can be made of plywood, or wood, or metal with a working surface. Coating can consist of one or more layers.
