Cotec Coatings use superior Exterior Wall Coatings
such as Kingfishers Weatherflex which is a high grade
exterior wall coating, formulated from a blend of acrylic
polymers and pigments, carefully selected for their
durability and depth of colour.
This exterior wall coating provides a guaranteed total
protection against all types of weather conditions for up
to 15 years ideal for applications to brickwork, stone,
masonry and most rendered finishes.
Originally developed as a flexible, waterproof coating,
Weatherflex exterior wall coating has earned a national
reputation for durability, weather protection and depth of
Weatheflex Exterior Wall Coating
Fills in cracks
Microporous surfaces coatings are impermeable to
liquid water, but permeable to water vapour. In other
words, they keep out the rain, but still allow the building
to dry out, or "breathe".

Cleaning and preparation is important with a masonry
surface as with any other surface. If anything the
advanced composition of these coatings means that
thorough preparing is more important than ever.
Preparing the wall includes removal of old flaking
coating and dirt residue. The most common cause of
flaking paint is moisture beneath the painted surface. It
must be removed prior to the application of the new
coating. This can be accomplished by pressure
washing, wet blasting or by scraping etc. if the surface
is in reasonable condition.
Exterior Wall Coating Preparation & Application
These areas will benefit from the application of a
Stabilising Solution which will:
‣ Improves paint adhesion
‣ Binds & primes chalking surfaces
‣ Stabilises flaky residues
Stabilising Solution allows you to effectively stabilise or
harden "less than perfect" walls or substrates in
preparation for the application of the Exterior Wall
Coating. Cracks in the masonry can be filled with a
flexible exterior filler.
Cotec use the Graco Airless Sprayer for the application
of exterior wall coatings.
This top of the range equipment allows us to apply
coatings to exacting standards ensuring that the finish
will stand the test of time.
The coating can be sprayed or rolled depending on the
substrate at an application rate of 1/2kg per sqm for
some pebble dash substrates but the application rate
will vary dependant on the porosity and substrate.
