W.A.W.C. work nationwide. We have based our success on working in an efficient and safe manner with quality workmanship being our goal.
Lime Mortar Render should be
PERFORMANCE IN USE
The hardened mortar should be:
Adequate vapour permeability
Appropriate degree of capillarity for the proposed use
Absorption rate not significantly greater than the host substrate
An elasticity that reflects the built condition and scale of the works
Sufficient tensile strength to suit the construction requirements
Suit the construction requirements
A bond strength sufficient to achieve a good wind and water-tight bond, never greater than the host masonry.
EASE OF USE
The mortar should: be
Workable when fresh to allow the work to be undertaken correctly
Remain workable for a sufficient length of time to allow appropriate finishing
Achieve an adequate degree of frost resistance at a sufficiently early age to avoid potential freeze/thaw risks.
Requirements for protection and curing should be taken into account at the specification stage.
COMPATIBILITY WITH ORIGINAL HISTORIC MATERIALS
The hardened mortar should:
Have a vapour-permeability similar to, or greater than, that of adjacent historic materials
Be visually compatible with surviving mortars and/or with the original appearance of the building
Reflect the historic integrity of the original materials and methods of construction where practical.
We travel all of Ireland applying out Lime Rendering techniques including Kerry, Cork, Tipperary and Waterford, even Galway, Mayo.
