Natural Finish is a pre-blended lime render with visible texture from the 2mm sand in a range of colours made with natural hydraulic lime. For application to brick, stone & flint.
A base coat of DURO is applied to the wall surface. Duro is a natural hydraulic lime base coat that benefits from increased workability for easy application and benefits from control of water loss and even curing. Applied in one coat of 15mm on straight walls in unexposed locations. Applied in two coats up to 20mm for uneven walls or exposed locations.
Natural Finish is the final coat which we supply in a range of natural colours. Applied in a single coat of 4mm. Natural Finish sheds most rainwater for added durability and for a more consistent finish during wet weather.

Packaging
22kg bags. Store in a cool dry place and use within 8 months.
Coverage
A 22kg bag of Natural Finish Render pure lime render will cover approx. 31/2 m2 at 4mm thick. This does not include any allowance for wastage.
Mixing/Water Addition
Add the whole bag of Natural Finish Render into a drum or forced action mixer carefully avoiding creating excessive dust. Add 3.5 – 4.5 litres of clean water per bag. Mix for at least 10 minutes using drum mixer or use a mechanical whisk for 3 minutes. Stand for 10 minutes then mix again for 3 minutes adding further water, if required, to achieve workable consistency.
Surface Preparation
Scratch basecoat of Ultra or Duro with a ‘nail’ or ‘devil’ float once the basecoat has hardened but is still ‘green’. Scratch in a tight spiral action making light grooves. Dampen surface with mist spray in sufficient quantity to reduce excessive suction before applying Natural Finish Render.
Application
Apply Natural Finish Render once the Duro or Ultra base coats have had sufficient time to cure. Usually 4 -7 days.
Natural Finish Render should be applied to a straight, keyed, flat, dampened surface in a number of passes each approximately 1-2mm thick, up to a maximum of 4mm. Each pass or layer of Natural Finish should be applied while the first pass of Natural Finish Render is still damp but has had time to “pull in”.
Avoid over working. Use only a light mist spray if applying water to the surface of the finishing coat.
Finish with wooden float and leave open textured or dress with a sponge to close off and reveal the aggregate texture.
Temperatures: Natural Finish Render should be applied in temperatures above 5 degrees C below 30 degrees C
Curing
Prevent all coats from drying out too rapidly. Lightly spray each coat with water if it is hot or the product is drying out too quickly. Protect from adverse conditions such as frost, rain and wind, ideally using a fully sheeted scaffold when outside.
Decoration
Natural Finish Render is a coloured render and does not require decoration but can be decorated with mineral paint. Allow approx. 24 days drying time before decorating with mineral paint. When decorating use breathable paints. Contact The Lime Centre for further advice or information about the full range of breathable paints.
