Description
Create a discreet waterproof barrier where your bath, shower tray or worktop meets the wall with the Spajet Flexi-Seal 4m Waterproofing Strip. Its flexible rubber construction accommodates movement, while the integrated butyl-based adhesive bonds to the edge before tiles or wall panels conceal the upstand. The pre-cut 4m length gives you room to work around longer wall junctions, provided you check the total required length before ordering.

Choosing the Right Length
Measure every edge that meets a wall, add those lengths together and allow for any corners or overlaps required by the installation instructions. The strip must cover the complete junction: do not shorten the protected area to make an insufficient length fit.
-
1700 × 700mm bath, one long edge and two short ends: 1700 + 700 + 700 = 3100mm before fitting allowances.
-
1700 × 700mm bath, two long edges and one short end: 1700 + 1700 + 700 = 4100mm before fitting allowances. A single 4m strip is not enough.
-
1200 × 800mm tray, one 1200mm edge and two 800mm edges: 2800mm before fitting allowances.
-
900 × 900mm tray, three edges: 2700mm before fitting allowances.
For shaped baths, measure the actual wall-contact edges rather than relying on the bath's overall dimensions.
Installation Guidance
Follow the supplied manufacturer's fitting instructions. Prepare clean, dry, dust-free contact surfaces, position the adhesive strip along the required edges and fit the upstand behind the wall finish. Check the specified sealant, corner treatment and overlap requirements before starting. This is a concealed installation component, not a decorative strip to cover an existing silicone joint.
Frequently Asked Questions
Will one 4m strip cover my bath or shower tray?
It depends on which edges meet the wall. Add the lengths of those edges and the manufacturer's fitting allowances. If the total exceeds 4m, choose a longer sealing solution; do not leave part of the junction unprotected.
Can I use it with a P-shaped or L-shaped bath?
Measure the actual wall-contact edges and check the fitting requirements for your bath. A shaped bath is not automatically covered by a 4m strip.
How does it differ from the 2m Flexi-Seal strip?
The pre-cut length is the main difference. Choose the length that covers your full installation, including any fitting allowances.
Can I fit it after tiling?
The upstand is designed to be concealed behind tiles or wall panels, so plan its installation before completing the wall finish. Follow the manufacturer's fitting sequence.
