Walther Strong 100mm x 90m Scrim Tape. High Strength Mesh Tape. Self-Adhesive Plasterboard Tape for Filling Cracks, Patching Holes and Reinforcing Joint Repair. HD Orange Plaster Tape

Seems to do the trick. Good quality, sufficiently adhesive to hold well.

This type of tape is required for cement isolation boards, used under tiles, normal scrim tape will break down over time. This was the cheapest by far and quick delivery

Its got a strong adhesion

As decsribed, reputable brand

Double the price of others and it isn't better at all

This is proper Scrim - its slightly thicker and heavier gauge than any other scrim, its very sticky - some will say its slightly too thick but if you want a scrim product that will give you reinforcement that won't let any cracks - this is the one.I have tried lots and lots of scrims - i'm staying with this one at last, Very quality product - and if you work it out per meter to the cheap stuff - its about £0.10 more per meter and ABSOLUTLEY WORTH IT what's 10p for the right resultThanks Walther

Watch out! This is only ONE roll of scrim. Very misleading picture of two rolls, at twice the price of the other brands!!!
