WBP Ply

[diytrainee]

I'm sure this is an easy question for you pro's but I just want to check.

I've bought some WBP plywood to overboard the bathroom, are both sides the same ie. the both have WBP coating as they are different shades on top and bottom. So basically does it matter which way round I put them down?

Cheers

Exterior WBP (weather and boil proof) ply refers to the the glue used. The quallity of the glue resists de-laminating when wet but it is manufactured using untreated timber veneers. There is no back and front so anyway up is ok. The different face finishes are probably due to a better quality veneer being used on one side than the other to save on manufacture cost but still give the customer one good smooth face for painting etc.
