 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. |
| COST
SAVINGS: 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.
|
| EXCELLENT ADHESION:
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. |
| EASY ON-SITE USE: RENO-PREP RENDER
supplied in 25kg polythene sacks, is subject to strict controls during manufacture
to ensure an even distribution of the ingredients, to eliminate the risk
of inconsistent on-site mixing. |
RENO-PREP RENDER WITH ITS UNIQUE FIBRE RE-INFORCEMENT
The fibres are added on site to suit substrate and site conditions. Please consult Renotex for details.
