Reno Prep Render

RENO PREP RENDER with its unique formulation, offers much greater workability than normal renders. The higher tensile strength provided by the reinforcement allows the traditional render application to be reduced in thickness. On blockwork or brickwork, an overall thickness of approximately 10mm is required, consisting of a 8mm basecoat and 2mm topcoat. The render can be applied as little as 2mm to feather out uneven edges of existing old renders, or for repairing old render.
Unlike conventional basecoats which are normally allowed to dry and crack before subsequent coats are applied, RENO PREP RENDER allows the finishing coat to be applied in 24 hours, depending on weather conditions, giving a significant reduction in 'time-on-site' costs.
RENO PREP RENDER has excellent adhesion properties to overcome problems associated with variable site conditions and poor substrates. This makes it ideal for building restoration projects and can easily be applied to sound stonework, brick or block surfaces.
RENO PREP RENDER supplied in 25kg bags, is subject to strict controls during manufacture to ensure an even distribution of the ingredients, to eliminate the risk of inconsistent on-site mixing.
The fibres are added on site to suit substrate and site conditions. Please consult Renotex for details.
RENO PREP RENDER can be applied to most surfaces including suitably prepared brickwork, blockwork or concrete. It may also be applied over metal lathing, Plastic tensar grid or insulation board system.
When RENO PREP RENDER basecoat is applied at a thickness of 8mm with a topcoat of 2mm giving a total thickness of 10mm, 14kg will cover 1 square metre.
