METHOD STATEMENT
LiquidRender 2000 (F/C)
1. DESCRIPTION
LiquidRender 2000 (F/C) is a high build ready-for-use polymer parge coat for quick and easy thin
section surface refinement on masonry surface, concrete surfaces including Fibre Cement Sheeting
and Autoclaved Aerated Concrete (AAC) blocks. It is applied as an essential surface foundation
coat before coating and painting applications. It is a polymer modified material to replace limewash and cement based skims and prevents the occurrence of normal aesthetic flaws such as
hairline cracks and efflorescence when used accordingly. LiquidRender 2000 is suitable for both
interior and exterior use.
2. SURFACE PREPARATION
General
All surfaces must be structurally sound and free from dirt, dust, oil, paint, wax, mould release
agents or any other contaminants that may interfere with adhesion.
Moisture content of the surface must be less than 15% at the time of coating.
Concrete Walls
All new concrete walls must be allowed to cure for at least 6 weeks.
Old concrete must be cleaned with detergent or degreaser. Wash off all residues thoroughly with
clean water and allow the surface to dry for at least 24 hours.
Under circumstances whereby the concrete wall is uneven, a layer of base coat measuring up to a
maximum of 3mm should be applied to create a smooth surface prior to the application of
LiquidRender 2000.
Plastered Walls
Apply a layer of base coat measuring up to a maximum of 3mm on the plastered surface to create a
smooth surface prior to the application of LiquidRender 2000. If necessary, a thin layer of skim
coat can be applied after base coat for an even better wall surface.
3. APPLICATION OF LIQUIDRENDER 2000
Apply LiquidRender 2000 straight from the tub using a flexible trowel. A flexible trowel with blade
length ranging from 300 – 600mm is used for leveling and smoothening of the finish coat forming a
smooth, flat and blemish free surface.
If dilution is required, a maximum of 5% by weight water can be added before using. Allow surface
to dry before applying either second coat or topcoat.
Freshly applied material must be protected from rain for a minimum of forty-eight (48) hours.
