MX Flexi Seal Strip — 2.8m — Waterproof Upstand for Flat Shower Trays The MX Flexi Seal Strip creates a professional waterproof upstand around the perimeter of a flat shower tray, allowing tiles to be fitted directly over it for a seamless, watertight finish. Applied to the tray before installation, the flexible strip accommodates natural building movement and settlement whilst maintaining a permanent seal at the vulnerable tray-to-wall junction. The 2.8m length and 70mm width provide complete coverage for a standard shower tray installation. Engineered by MX for professional-grade waterproofing performance. ⚠️ For flat shower trays only. This strip is designed for use with flat (zero-upstand) shower trays where a tiled upstand is required. It is not suitable for trays with a pre-formed upstand. Apply to the tray perimeter before positioning the tray. Key Features 2.8m length × 70mm width — sufficient for complete perimeter coverage of a standard shower tray Flexible construction — accommodates building movement and settlement without cracking the seal Tile-over design — tiles are fitted directly over the upstand for a seamless finish Waterproof upstand — prevents water ingress at the tray-to-wall junction Professional-grade performance — engineered by MX for reliable, long-lasting waterproofing Suitable for professional fitters and competent DIY Technical Specification Brand: MX SKU: WAY EAN: 5017706771252 Type: Flexible waterproofing upstand strip Length: 2.8 metres Width: 70mm Weight: 1kg Application: Flat shower trays — applied to tray perimeter before installation Compatible with: Flat (zero-upstand) shower trays Installation: Apply strip to tray perimeter; tile over upstand once tray is positioned How It Works The Flexi Seal Strip is applied around the perimeter of the flat shower tray before the tray is positioned. Once the tray is in place, the 70mm wide flexible upstand extends above the tray surface. Tiles are then fitted over the upstand, creating a continuous waterproof barrier between the tray and the tiled wall. The flexible material allows for natural building movement without compromising the seal. Suitable For Flat shower tray installations requiring a tiled upstand Standard shower enclosures — 2.8m covers a full perimeter Walk-in shower installations Wet room shower areas with flat trays New builds and bathroom renovations Commercial bathroom projects Coordinate Your Shower Installation Shower Trays — browse compatible flat shower trays Shower Enclosures — complete your shower installation Shower Valves & Accessories — valves, heads, and arms Frequently Asked Questions What is a Flexi Seal Strip used for? A Flexi Seal Strip creates a waterproof upstand around the perimeter of a flat shower tray. Flat trays have no pre-formed upstand, so without a seal strip, water can penetrate the junction between the tray and the wall. The strip is applied before the tray is installed; tiles are then fitted over it to create a seamless, watertight barrier. It is an essential component for any flat shower tray installation where a tiled finish is required. What are the dimensions of this strip? The MX Flexi Seal Strip is 2.8 metres long and 70mm wide, weighing 1kg. The 70mm width creates a generous upstand above the tray surface, providing ample coverage for tiling over. The 2.8m length is sufficient for the full perimeter of most standard shower tray installations. Is this strip suitable for all shower trays? This strip is designed for flat (zero-upstand) shower trays only. It is not required for trays with a pre-formed upstand, as those trays already have a raised edge to seal against the wall. If you are unsure whether your tray requires a seal strip, call us on 01603 381095 and we can advise. Will 2.8m cover my shower tray? The 2.8m length covers the full perimeter of most standard shower tray installations. The strip only needs to cover the sides that meet the wall — typically 3 sides for a corner installation, or 2 sides for a recess. For a 900mm corner installation: 2 sides = 1.8m; 3 sides = 2.7m, which the 2.8m strip covers with minimal waste. For larger trays or 4-sided installations, you may need more than one strip. Measure your installation before ordering to confirm. When should the strip be applied? The Flexi Seal Strip should be applied to the perimeter of the shower tray before the tray is positioned. Once the strip is in place and the tray is installed, tiles are fitted over the upstand. Follow the manufacturer’s installation instructions supplied with the product for best results. Can a competent DIYer install this? Yes — the MX Flexi Seal Strip is suitable for professional bathroom fitters and competent DIY enthusiasts. Correct application is important to ensure a watertight seal — follow the installation instructions carefully. If you are unsure, professional installation is recommended. Can I order if the item shows as out of stock? Yes — this product is available to order even when stock shows as zero. Please allow additional lead time and contact us on 01603 381095 to confirm availability.

The Classi Seal Waterproofing Strip (SKU: CS025) is a professional self-adhesive tanking strip designed to create a reliable secondary waterproof seal between shower trays or baths and bathroom walls. Applied before installation, it creates a flexible membrane behind the tiles that accommodates up to 15mm of building movement — providing far superior long-term protection compared to silicone sealant alone. Sold per metre, cut fresh from a 25m roll, so you order exactly what you need with no waste. 📏 Sold per metre — enter the quantity in metres at checkout.For example, quantity 3 = 3 metres, quantity 5 = 5 metres. How much do you need? Standard shower tray or bath (3 sides): approx. 3–3.5m · Large enclosure: 4–5m · Add 10% for trimming. For a standard pre-cut length, see the Classi Seal 3.2m Pre-Cut Strip (CS032).

We cut your exact length fresh from a 25m roll. As a guide: a standard shower tray or bath on 3 sides requires approximately 3–3.5 metres. Add 10% for trimming. If in doubt, order slightly more — offcuts can be used for future repairs or smaller projects. Why use a tanking strip instead of silicone alone?Silicone sealant is the first line of defence but has limitations — building movement, settlement, and thermal expansion can cause silicone to crack or separate over time. Classi Seal provides a critical secondary barrier: a flexible waterproof membrane behind the tiles that accommodates up to 15mm of movement without failing. Even if the silicone joint cracks, the tanking strip prevents water from reaching the substrate. This dual-layer approach is considered best practice by professional bathroom installers. Can I tile immediately after applying Classi Seal?Yes — no curing time is required. Once the strip is applied and the tray or bath is positioned, you can tile over the upstand immediately. The base edge should be sealed with neutral cure silicone once tiling is complete. What type of silicone should I use?Always use neutral cure silicone (not acetic/vinegar cure). Acetic cure silicone releases acetic acid during curing which can damage the adhesive and membrane. Neutral cure silicone is widely available and is the correct choice for use with tanking strips and most bathroom materials. Is there a pre-cut version available?Yes — the Classi Seal 3.2m Pre-Cut Strip (CS032) is ideal for a single standard shower tray or bath installation with no measuring required. The per-metre option (this product) is best when you need a specific custom length, are completing multiple bathrooms, or want to avoid waste. Can I order if the item shows as out of stock?Yes — we can fulfil this product even when stock shows as zero. Place your order as normal and we’ll confirm lead time with you.
