DESCRIPTION
Wykamol Renovating Plaster is a pre-mixed cement-based lightweight plaster containing Perlite aggregate
and water-repellent additives and is manufactured under a quality system complying with BS EN ISO
9001:1994. It is particularly useful where improved thermal performance is required, reducing the risk of
condensation on external walls. It should be used as detailed below and in accordance with the general
recommendations in BS 5492:1990 Code of Practice for Interior Plastering. May also be used in conjunction
with Wykamol Render Additive 611, a wax-emulsion based waterproofing additive suitable for lime-based
mixes, thereby improving the overall resistance to moisture and salts.
SITE WORK
Mixing: Machine mixing time should not exceed 5 minutes. When mixing by hand add half the contents of the
bag to water (approx. 12-14 litres) and mix. The remainder of the bag can then be added (with more water if
required) to obtain the correct consistency. It is easier to use Wykamol Renovating Plaster if it is allowed to
stand for several minutes prior to application to the wall.
Application: Wykamol Renovating Plaster is applied in one coat 10-15 mm thick. If greater thicknesses are
required additional coats can be applied. The surface should be combed or lightly scratched between coats
and prior to application of the finishing coat to provide a mechanical key and should be stopped at least 25mm
short of the floor.
