Ultra Lime Plaster/Render Base Coat

Thermally insulating lime base coat with recycled glass bubble aggregate

Delivery only 10kg Coverage: Approx. 1.5m2 at 10mm per 10kg bag

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

Ultra is a highly insulating lightweight lime render and lime plaster base coat that is five to ten times thermally more efficient than other lime renders by using lightweight glass bubbles instead of sand.

This makes it the perfect plastering base coat for building renovations, where it gives an additional insulation layer to internal walls and protects against salt damage.

As an insulating lime plaster, Ultra Lime Plaster 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 commercial lime plasters, which means Ultra Lime Natural uses less energy to manufacture and is significantly lighter to transport, so cutting down on distribution costs and energy.

Ultra lime plaster base coat is applied to walls in the same way as conventional lime plasters. It has good ‘workability’ and there are no complicated fixings or problems achieving the right depth of coat.

Application Guide

Apply to walls in the same way as conventional lime plasters. Used as a base coat for building renovations, providing an additional insulation layer to internal walls. Has good workability and no complicated fixings.

Only use Ultra above 5°C and below 30°C. Ultra should be applied to a straight, flat, dampened surface in a uniform thickness of between 10 and 30mm, make sure this coat is keyed. After 2 to 7 days and the coat has stiffened/hardened, but is still ‘green’ more coats may be added.

Suitable fiinishing coats are Lime Green Natural Finish, Lime Green Solo or Fine Stuff, applied once the Ultra has set.
