Duro

Lime Green Duro is a premixed lime render and lime plaster basecoat.

Finished externally with a topcoat of Natural Finish available in a range of colours or finished internally with Solo lime plaster.

Duro is a breathable product made with natural hydraulic lime, ideal for old buildings.


Packaging

25kg sacks. Store in a cool dry place and use within 8 months

Yield/Coverage

A 25kg bag will cover approx. 1.5m2 at 10mm thick. This does not include any allowance for wastage.

Surface Preparation

Remove dust, surface contaminants and loose or friable existing render/plaster. Where necessary consolidate or dub out any deep holes with Duro and key.

Ensure masonry is not waterproofed or painted, do not apply PVA. Dampen the surface with a mist spray in sufficient quantity to reduce excess suction.

Mixing/Water Addition

Add the whole bag of pre-mix into drum mixer carefully avoiding creating excessive dust. Add 4-5 litres of clean water to each 25kg sack. Mix for up to 10 minutes in a mixer, or use a mechanical whisk for 2-3 minutes, stand for 10 minutes, then mix once more before application. Do not add anything other than clean water.

Application

Externally 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.

Internally applied in one coat of 15mm. A second coat may be needed to straighten the wall surface ready for Solo plaster skim coat.

Each coat must be scratched to give a good mechanical key before further coats are applied. Dampen down the surface prior to coating. A second Duro coat maybe applied after the previous has adequately cured, usually 2-4 days. Ensure it is thinner than the first. Key the final coat of Duro whilst still green with a nail or devil float before applying the 5mm topcoat of Natural Finish for external work or 3mm skim coat of Solo lime plaster for internal work.

Temperatures: above 5oC and below 30oC.

Reworking: up to 8 hours.

Further coats: after 2 to 7 days, once the coat has stiffened/ hardened, but is still ‘green’

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, etc.

Adequate curing of a final decorative coat should be more stringent, ideally using a fully sheeted scaffold when outside.

Finish Coat

Finish externally with 4mm of Natural Finish available in a range of colours or internally with 3mm of Solo lime plaster.
