Ultra Lime Render Base Coat

Lime Green Ultra is a thermally insulating lime basecoat that can be used for rendering and plastering.

Ultra Natural is a highly insulating lime render base coat that is five to ten times thermally more efficient than other lime renders when tested in accordance with British Standards. This makes it the perfect insulating lime render base coat for building renovations, where it gives an additional insulation layer to external walls.

Lime Green's Ultra Natural is such an effective insulator because it contains an aggregate of hollow beads made from recycled glass, which can make up to 55% of its bulk. This replaces the sand conventionally used in standard lime render and lime plaster, which means Ultra Natural uses less energy to manufacture and is significantly lighter to transport, so cutting down on distribution costs and energy.

Ultra Natural is applied to walls in the same way as other lime renders and lime plasters. It has good ‘workability' and there are no complicated fixings or problems achieving the right depth of coat.

You can buy Ultra Natural directly from us or through a range of national merchants. We maintain good stocks, you can be sure of a high level of availability even for larger projects.

Packaging

For handling purposes, assume 10 kg per bag, 80 per pallet shrink wrapped

Coverage

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

Properly prepare the surface before application.

Remove dust, surface contaminants and loose or friable coatings. Apply Beecks Fungicide if necessary. On dense impervious backgrounds apply Lime green Natural Stipple for improved bond.

Ultra can be mixed using a drum mixer, or in a tub using a plasterers paddle mixer. Spray render machines may also be suitable Always mix with clean water; do not add anything else.

Mixing

Add approximately 4-4.5 litres. Mix for 5 to 10 minutes.

Temperatures: above 5°C and below 30°C.

Application

Apply a coat of Ultra Natural between 10 to 30 mm thick directly to dampened substrate. Each coat must be scratched while wet to give a good mechanical key before further coats are applied. If the substrate is very dry, dampen down the surface thoroughly prior to coating.

Use lime green Natural finish as the finish coat 2 to 7 days afterwards; once the coat has stiffened / hardened, but is still "green‟.
