Res Tec Acryltex Waterproofing Roof Repair

Res Tec Acryltex is a ready-to-use acrylic roof repair coating containing reinforcing fibres. It is intended to provide a protective coating on appropriate roofing backgrounds and to help bridge small cracks or defects where the surface and repair detail are suitable. The available choices are Grey or Black, each in either 5kg or 20kg containers.

Fibre-reinforced roof repair coating for localised maintenance

Unlike a sheet roofing membrane, this is a brush-applied or similarly applied liquid repair product. The integrated fibres are a key distinction, but they do not make the product a substitute for replacing saturated, rotten or structurally unsound roofing. The correct repair also depends on the substrate, previous coatings and existing roof drainage.

Choosing the right option

Identify whether the problem is a small surface defect or a failure of a larger roofing component. Check that the existing felt, sheet, metal or other substrate is within the manufacturer's approved list. Calculate the area of all upstands, laps and details as well as the flat surface, using the current product coverage rate rather than estimating from container weight alone.

Installation, preparation and ordering advice

Prepare the surface and use any primer, reinforcement or additional coat specified for the particular roof condition. Do not rely on general claims of instant waterproofing or all-weather application: check substrate moisture, weather forecast and temperature limits against Res Tec's current instructions. Working at height requires appropriate safety precautions and safe access.

Roof Tiles & Fittings:

We recommend ordering an additional 10% of roof tiles to allow for any breakages that may occur during delivery or handling. Roof tiles are naturally fragile, and having a few extra on site helps prevent delays and ensures your roofing project can be completed without interruption.
