Conditioning

How to avoid movement when your OSB boards are fitted

Condition your OSB boards to get them used to the in-use atmosphere of the room before fixing them in place
To do this, stack them loosely in the in-use (or as close as possible) moisture and temperature conditions for a minimum of 48 hours preferably a week
Avoid damp or wet conditions if possible
If boards are exposed to water, let them dry before applying any weather-proof finishes or making them take their full design load
