As with all painting projects the surface needs to sound, clean and dry, if you walk around your building you will see with your eye what it is like, feel the surface, rub your hand over the surface (always wear gloves to protect your skin) and check that there are no loose flakes, or any visual signs of algae.

If you scrap down the wall to clean off any old paint flakes this will help to tighten up the surface, always wear the appropriate eye protection and dust mask, if there is any dirt, dust etc. wash down your walls with a domestic power washer, if any algae or mould is present using a stiff bristle brush (not wire) agitate the algae use our Sterilising Solution and apply liberally over the algae (please follow application instructions). Allow to dry for 24 hours, if there are areas heavily infected with algae or mould, apply the concentrated sterilising solution full strength over the effected area and leave to dry do not wash off.

If the surface is friable or powdery in certain areas, you can apply our stabilizing masonry sealer which will help properly prepare the surface prior to painting. This is a simple one coat application of our water-based sealer.

If applying Smooth Masonry on to sound new render walls the 1st coating can be thinned with water by 10% to seal the surface and the second coat is to be applied full strength.

If you require specifications for your project please contact our offices. Exterior Paints

Completely remove all traces of loose, flaking soft and friable paint back to a clean firm surface by scraping and or washing. Remove any existing mould growth by scraping or brushing with a stiff fibre brush, (NOT wire).

Thoroughly abrade any glossy surfaces with glass paper to achieve a good key.

A second application of Proud® Paints Sterilising Solution is recommended for heavily infected areas. Prime or tape any copper or other metal surfaces with an appropriate primer and allow to dry.

Do I Need a Stain Block?

Why does Proud® Paints Anti Mould Paint work and Others Don’t?

Other Fungicidal/Anti-Mould paints use an additive which is mixed into an already made Emulsion Paint. This means that not all of the paint will carry the same amount of the Fungicide which protects against Mould growth.

Proud® Paints Anti Mould Paint uses an Acrylic Resin and their own Fungicide and an Algaecide which forms a thermal barrier to areas subject to varying temperatures and condensation, eg kitchens, bathrooms, shower rooms, bedrooms, Living Rooms etc.

All of the constituents of the paint are added in a formulated process and dispersed to ensure that all the pigments and constituents including UV stabilisers, algaecides, and fungicides are coated evenly in the paint blend to produce a paint that is consistent, stable and which will promote all of its anti-fungal properties to our extremely high specification.

This ensures that every part of Proud® Paints Anti Mould Paint carries the same amount of the active biocide and when applied every part of the surface will be protected.

Ideal for any ‘Internal’ areas that are susceptible to Mould or Organic growth

With very slow even strokes, lay onto wall in heavy patches. Do not worry about the texture at this point in time.

When the initial quantity of product is on the wall, slowly and evenly spread out to cover a larger area.

The texture can now be achieved by further rolling and jointing of areas using a diagonal action. The texture is achieved by laying off.

Always finish on the up stroke, in order to push the marble aggregate into vertical position. This will ensure that the texture will have a ‘peaked’ effect when dry.
