Description
Dunlop Render Joint & Patch is a high-performance, two-in-one compound for rendering projects: it joints fibre cement sheet and blueboard before render is applied, and it patches cracks and holes in existing rendered surfaces up to 5mm deep or wide. Supplied premixed in a light grey colour that blends into most render systems, it takes the fuss out of preparation work — one pail handles both the sheet joints and the surface defects before your finishing coat goes on. The 4L size is perfect for repairs and smaller rendering jobs.
Where to use it
On interior and exterior walls. As a jointing compound, use it over blueboard and fibre cement sheet prior to rendering. As a patching compound, use it over sound existing render to fill hairline cracks, chips, divots and small holes before re-coating or painting.
How to use
Surfaces must be clean, dry, sound and free of dust, loose render and contaminants. Stir the pail, then trowel the compound firmly over sheet joints (embedding tape where the sheet system requires) or press it into cracks and holes, striking off flush with the surrounding surface. Feather edges smooth with a trowel — the Dunlop Gauging Trowel gives a professional finish. Allow to dry fully before applying render, texture or paint, and wash tools in water straight after use.
Important notes
Maximum patch depth or width is 5mm — build deeper repairs in stages or use a repair mortar. Drying time lengthens in cold or humid conditions. Not intended for structural crack repair or designed movement joints.
