Description

Create a Reliable Waterproof Barrier

Double MEGATAPE from Beava Tiling forms a 100% waterproof seal between sanitary ware and adjacent walls. Its self-adhesive bitumen strips mean you simply press it in place—no extra glue or sealant required. This first-fix solution saves time and ensures a neat, lasting bond.

Flexible Design for Movement

New builds and renovations often face settlement and structural shifts. Double MEGATAPE flexes to accommodate vertical movement of up to 30 mm without breaking the seal. As a result, you reduce the risk of cracks or leaks around baths, basins, shower trays and kitchen worktops.

Thin Profile for Tight Corners

Thanks to its slim, flexible construction, the tape slips easily into corners. It won’t push tiles forward or distort small mosaics. You get a clean line and uniform grout joints, even in areas where space is limited.

Wide Range of Applications

While ideal for sanitary ware upstands, this tape also works between kitchen countertops and splashbacks. Tilers use it under wetroom panels, around bath edges and behind vanity units. You can also seal control panels, pipe entries and any junction where water resistance is vital.

Simple Installation and Cleanup

Cut the tape to length, peel back the liner and press firmly against your clean, dry surface. The bitumen strips adhere instantly, so you can continue tiling or plumbing without delay. Excess tape can be trimmed neatly, and the thin profile hides under trims and tiles.

Packaging and Size Options

Choose from three convenient lengths:

  • 2.5 m roll (SKU 83405)

  • 3.2 m roll (SKU 83404)

  • 25 m bulk roll (SKU 83403)

Each roll comes in branded, sealed packaging to protect the tape until use.


Trust Double MEGATAPE for every project that demands a tough, flexible, waterproof seal. Whether you’re a professional tiler or a keen DIYer, this double-sided tape delivers speed, ease and long-term peace of mind.
