OSB Board FAQs

OSB is engineered to resist water and has a smooth finish so applying plaster can be tough. With the preparation of roofing paper and wire mesh, the plaster will adhere to walls.
OSB board contains formaldehyde-based waterproof resin called phenol-formaldehyde. Acute exposure is irritating to the eyes, nose and throat. Heavy exposure can cause allergic reactions of the eyes, skin and respiratory tract.
OSB board is mainly used for floor, walls and roof sheathing.
OSB comes in a variety of thicknesses, starting from 6mm all the way up to 28mm.
A wood preserver is a good choice as it helps to repel the water.
No, you cannot use OSB board outside it is not water or moisture resistant.
One disadvantage is that it is not moisture resistant so if in contact with moist or humid conditions, it will expand.
