Dunlop Render Joint & Patch in the 10L trade pail is a high-performance combination product that covers two essential preparation steps in one: jointing fibre cement sheet and blueboard ahead of rendering, and patching cracks and holes up to 5mm in existing rendered walls. Premixed to a smooth, light grey consistency, it goes straight from pail to trowel with no mixing, keeping preparation fast and consistent across large jobs. The 10L size is the economical choice for renderers and builders working across full elevations or multiple rooms.Where to use itIndoors and outdoors on walls. Use as a jointing compound over blueboard and fibre cement sheeting before render systems are applied, and as a patching compound over sound existing render to make good cracks, holes and surface defects up to 5mm deep or wide before re-rendering, texture coating or painting.How to usePrepare a clean, dry, sound surface free of dust, loose material and contaminants. Trowel the compound firmly across sheet joints, embedding jointing tape where required by the sheet manufacturer, and feather the edges flush. For patching, press the compound into the defect, strike off level and smooth the surface – the Dunlop Gauging Trowel helps achieve a professional finish. Allow to dry completely before over-coating, and clean tools with water while the product is still wet.Important notesRepairs deeper or wider than 5mm need staged applications or a dedicated repair mortar. Cold, damp or humid weather extends drying times. Do not use across designed movement joints – finish those with a flexible sealant.Specifications Size 10L pail Colour Light Grey Patch capacity Cracks and holes up to 5mm (depth or width) Location Indoor and outdoor walls SafetyWater-based product.
