Product Description:

Limelite Whitewall One Coat Plaster is a pre-blended, one coat plaster that is applied like a standard backing plaster but gives the finish and durability of a first-class finishing plaster. Whitewall One Coat is resistant to humidity and is therefore ideal for use with cavity drain membranes.

Tough, hard wearing finish
Whitewall One Coat provides a tough finish that is highly resistant to impact and casual damage.

Versatile
Can be used on a wide range of traditional substrates such as solid brick and stone. It can also be used on walls that have previously suffered from damp or flooding.

Easy to use
Limelite Whitewall One Coat Plaster is lightweight, easy to mix and is applied using standard plastering tools and techniques without any additional training requirement. It is applied like a backing plaster yet has the finished appearance of a finishing plaster

No need to paint
Limelite Whitewall One Coat Plaster makes it easy to achieve a smooth, matt off white finish that can be left unpainted for a natural look. This saves on decorating costs.

Responsibly sourced
All of our products are manufactured in the UK and certified under BES 6001 Responsible sourcing. Tarmac was the first company within the cement and lime sectors to be awarded the BES6001 ‘Excellent’ rating across its entire product range.

Mixing Instructions

For best results Limelite Whitewall One Coat Plaster should be mixed in a clean mixing vessel using a mechanical mixer such as a slow-speed drill and paddle mixer.

Fill bucket with between 8.75-11.25 litres of clean water and add 25kg of dry powder to the water and mix for 2-3 minutes until a smooth, homogeneous working consistency is achieved.

Allow to rest for 3 - 5 minutes, then re-mix back to consistency adding small amounts of water if necessary.

Application Instructions

Substrates should be cleaned and any loose or friable material removed. Traces of gypsum plaster, bitumen or other materials that could cause a barrier to adhesion must be removed.

Substrates should be primed with Limelite Easy-Bond and the first coat of plaster should be applied once the priming coat is tacky.

The plaster should be applied in coats between 7-15mm and a minimum of 24 hours is required between coats. A suitable horizontal scratch should be applied between each coat for a key.

Clean Up & Spillages

Tools and equipment can easily be cleaned using water. Cleaning of tools and equipment should be carried out as soon as possible after application.
