    Technical Information Sheet

    Use Silicate Masonry Paint can be used on all mineral-based surfaces, eg, stone, masonry, concrete, pebble dash and plaster surfaces. It can be used both internally and externally and is especially suitable for renovation work to historic buildings and for covering old, sound silicate-based paints.


    Siliacate Masonry Paint is a white paint that has excellent covering properties and is virtually non-drip. It is breathable and can assist in regulating the humidity of the internal environment. It is weather resistant and washable. It dries to a soft matt finish and does not yellow with time.


    White. A range of other colours is available to special order. .
    Sizes 10 litre container Product No. 1703
    Coverage Approximately 5-7 square metres per litre


    The surface must be sound, absorbent and dry. It must also be clean, dust and grease free. Prime the surface with one coat of Silicate Primer and allow to dry before applying Silicate Paint. Carefully mask all adjacent glass, metal, ceramic etc., before use.


    Do not use if the working temperature is below 8C.

    Always stir the paint well before use and at regular intervals during use.

    Silicate Paint can be applied with a brush, roller or spray gun.

    Apply thin, even, well-spread coats. Keep a wet edge whilst painting and complete each wall/section in one go. Apply the second coat in the opposite direction to the first coat.

    For all external surfaces, apply the first coat diluted with up to 20% Silicate Primer. Ensure each coat of paint is dry before applying the next coat.

    Any paint splashes should be washed off immediately with plenty of water.


    Silicate Paint can be tinted using NBT Pigments.

    Never use oil or acrylic artists’ colours or commercial tinters.

    Use no more than 375g Pigment per 5 litres Silicate Paint, ie. 75g per litre (7.5g in 100ml).

    Soak Pigment in enough Silicate Primer to cover the powder, and mix well to create a liquid paste. Pour paste into Silicate Paint and stir with a whisk until completely blended.

    Ensure the paint is applied in even coats, as some high-intensity colour tones can become patchy when dry.

    Note: Colour Concentrates are not suitable for this product. Not all NBT pigments are suitable for use with Silicate Masonry Paint. Please refer to Note “A”, attached to this technical sheet, for a comprehensive list of which NBT pigments are suitable for use. When pigments are added, Silicate Masonry Paint must be used immediately to avoid colour changes.

    Note: When Pigments are added Silicate Paint must be used immediately to avoid colour changes.
