Earles Masonry Paint is composed of a blend of natural minerals without the addition of polymers, plastics or harmful inorganic chemicals. It is supplied as a fine powder which is mixed with water to form an easily applied coating. Breathable and weather resistant Earles Masonry Paint cures to a super matt finish.
Consumption will depend on the porosity/texture of the surface and the required finishing application method. The following table is illustrative of the application of one coat of Earles Masonry Paint using 1KG, 5KG and 10KG of powder on a smooth rendered surface.
Coverage given for unmixed dry powder per coat.
| Surface | per KG | per 10KG tub |
|---|---|---|
| Smooth render | 4 – 6m2 | 40 – 60m2 |
| Pebbledash | 2 – 3.5m2 | 20 – 35m2 |
| Concrete blocks | 3 – 5.5m2 | 30 – 55m2 |
| Wall and fibre boards | 5 – 7m2 | 50 – 70m2 |
| Suitable brickwork | 4 – 6m2 | 40 – 60m2 |
Ensure the surface is free of all weak and loose deposits and contamination such as dust, dirt, moss, lichen, grease, oil, sealer and anything that could affect the coating application.
Note: For application onto existing paint, where the previous paint has failed leaving areas of bare masonry, additional preparation is required. Apply two coats of Earles Masonry Paint onto the bare masonry areas before painting the entire surface with a further two coats of the paint. This will ensure the most even finish.
Earles Masonry Paint Surface Primer is essential when the paint is to be applied over any non-porous surfaces such as polymer based coatings, glazed bricks, or old unpainted renders and old pebble dash or other loose and friable surfaces.
Mix the paint by volume using equal quantities of water and powder to mix the paint, for example one cup of water to one cup of powder.
A minimum of 2 coats of Earles Mineral Paint is recommended.
If Earles Masonry Paint Surface Primer has not been necessary, wet the surface down just prior to paint application. This is vital to stop the substrate drawing moisture out of the paint.
Apply the first coat of paint evenly to the surface using a brush, an HVLP or compressor based spray system. Do not use an airless spray system. Spray application will give the smoothest finish and the most consistent thickness of paint. If brush application is preferred it is essential to ensure that an equal thickness of paint is applied evenly over the whole surface.
Due to the lack of any polymer content in Earles Masonry Paint, airless spray systems are not recommended.
Allow a minimum of 6-8 hours between coats under normal circumstances. A longer curing time may be necessary in cold and damp conditions.
Apply a second coat of the paint and allow it to fully cure.
Further coats of paint may be necessary in circumstances where the background is of a dark colour.
Prepare the Earles Masonry Paint mix ready for use. Thoroughly saturate the surface with water and immediately commence painting. If rapid drying is apparent after 1 hour, mist the coated surface with water, this will aid the curing process. Repeat this process for the second coat of paint.
Earles Masonry Paint is unique, it cures by hydration and during this process it is normal for the paint to appear chalky or slightly transparent. The paint will oxidise and initial curing will be complete within 7 days. After this initial cure the paint will continue to strengthen over time, resulting in a super matt, dust free finish.
Note: If applying onto mixed substrates or existing failed polymer paint there will be varying moisture content already present within the walls and some initial colour variation may be visible. As paint hydrates and cures, the moisture will be drawn out of the wall and the colour will even out.
Simply clean all equipment with fresh water immediately after use.
