Weathercoat is an economical, permanent waterproofing
system for roofs and facades. The system will adhere
to new and old surfaces of concrete, bitumen, and
tiles. Weathercoat has long-life flexibility and
is ideally suited for use in areas with extreme
climatic conditions. It is applied by brush or spray
and after drying can be walked upon uncovered. After
application the Weathercoat system has high resistance
to chemical attack, atmospheric pollution, UV light
and fire.

|
| PROPERTIES:
Weathercoat is supplied as a two component, powder(cement
based) and resin (acrylic based), system, to be
mixed on site. Different mixing ratios will produce
compounds of different degrees of flexibility, suitable
for different purposes.
Weathercoat Resin
Is based on concentrated Acrylic resins, highly
resistant to UV light and alkalinity. The system
is permanently flexible and miscible with cement
and cement based materials in all proportions. Although
developed as a high class waterproofing system,
it is very suitable as an additive to mortars and
screeds to increase their tensile, compressive and
flexural strengths and reduces their water cement
ratio.
Weathercoat Powder
Is based on special cements and precisely graded
fillers, wetting and adhesion promoters. Properties
of the final mix will vary according to the ratio
of powder to resin.

ADVANTAGES:
• Permanent waterproofing
• Abrasion resistant
• Non-toxic ideal for water tanks
• Weather resistant
• High adhesion power
• Highly flexible
• Vapour permeable
• Cement Mortars adhere to it
• Bridges cracks in substrates
|
| |
| AREA OF
USE: |
For waterproofing most building surfaces e.g. roofs
, facades, foundations, retaining walls, swimming
pools, planters, wet room floors, water tanks etc.
|
| |
| |
| PREPARATION
OF SURFACE: |
Ensure all dirt and foreign matter are cleaned off
the areas to be coated. Remove any ridges or form
oil. Dusty or flaking surfaces must be cleaned thoroughly,
then primed with Weathercoat Primer or Terrabond A
or a 1:1 solution of Weathercoat Resin in water. |
| |
| |
| APPLICATION
AND CLEANING OF TOOLS: |
Mix the components in the ratios shown in the table
below. Add powder to Resin and use a high speed mixer
or power agitator until the mix is homogenous. If
spraying add enough water to bring to the correct
consistency.
Apply using brush, roller or spray, leave 3 hours
between coats for drying. Mixed Weathercoat must be
used within 1 hour of mixing.
