Shuttered Concrete Wall


Substrate

Concrete walls are to be smooth off-shutter (board-joints rubbed smooth and ferrule holes filled) and to be free of voids and honeycombing. Care is to be taken to remove shutter release oils and all remnants of curing compounds. The concrete is to be cured and dry - generally accepted when the bituminous prime coat achieves full adhesion.
