Dot and dab versus battens
Board can be stuck to a solid wall with adhesive dabs, or fixed to timber battens. Dabs are quick and lose the least room space. Battens are useful where the wall is very irregular, where a service void is wanted, or where the wall has a history of damp and the board should not sit tight against it.
We will recommend one after looking at the wall rather than defaulting to whichever is quicker.
