Overview

Waterproofing systems often fail at the joints rather than the surface itself. STRATAFLEX Seam Tape is designed to secure those weak points by forming a continuous watertight seal along seams, corners, and floor-to-wall transitions. Made from a double-stick elastomeric material, it bonds firmly with the help of an NAC primer, giving a fast and durable fix. Once applied, flooring or tile installation can continue the same day without holding up the job.

Key Features

Uses double-stick elastomeric construction for strong, lasting adhesion.
Seals joints, seams, corners, and transitions where water is most likely to creep in.
Works in both interior and exterior waterproofing applications.
Designed to pair with NAC primer for a secure bond.
Allows same-day flooring installation to reduce site downtime.

Where to Use It

STRATAFLEX Seam Tape is commonly used in wet areas such as bathrooms, showers, and laundries, where water ingress quickly damages substrates. It also performs well outdoors on balconies, decks, and terraces exposed to the weather. Commercial spaces that demand consistent waterproofing, like kitchens or washrooms, benefit from the speed and reliability this tape provides.

How to Use

Start by preparing the surface, making sure it is clean, dry, and properly primed with NAC primer. Roll the tape over the seam or joint, pressing it firmly into place for full contact. Overlap adjoining strips slightly to keep the barrier unbroken. Once applied, the area is ready for tiling or floor finishes the same day.

Compatible Surfaces

Concrete slabs and screeds
Cement-based boards and plaster finishes
Plywood and timber underlay (when primed)
Existing tiled surfaces (with primer)

Appearance

Supplied as a 6-inch-wide roll of elastomeric double-stick tape with a peel-away backing for straightforward application.

Pro Tip

At floor-to-wall junctions, run the tape slightly higher than the skirting line. This adds an extra layer of protection if water pools against the base of the wall.

Appearance

Supplied as a 6” wide roll of elastomeric double-stick tape with a durable backing that peels away during installation.

Pro Tip

On floor-to-wall transitions, run the tape a little higher than the skirting line. This gives extra coverage and peace of mind if water ever pools against the wall.
