What do you say, good quality tape.

Graham Walter

Good product, does its job, but the glue backing is not that strong on the fluffy side of the waterproof underlay.

Ask a question

Our experts will answer it

When using this tape with the Woodtex Premier Underlay Built-in Vapour Barrier EWA1, should it be stuck on the bottom foil layer or the top?
Obviously it's much easy to stick over the top of joints, than to have to turn over every strip.


Yes you can put the vapour tape over the top of the underlay, this will stop any moisture coming through the joins of the underlay.
