18mm Moisture-Resistant MDF Board
£25.98 +VAT
MDF (Medium Density Fibre) board is a commonly used particle board. Moisture Resistant MDF is used in places with high humidity levels. In comparison to standard MDF, Moisture Resistant MDF (or MR MDF) contains a moisture-repellent resin which gives it a better moisture resistant rating. However, MR MDF shouldn’t be mistaken to be water resistant as it’s still prone to swelling and warping if in direct contact with such elements.

Really impressed with the quality of this 18 mm moisture-resistant MDF from Wel Timber. The boards were perfectly flat, clean-cut, and ideal for the fitted units I was building. Delivery arrived the next morning as promised, and the team were helpful and professional from start to finish. Great service, great product — I’ll definitely be ordering again.
