Dulux Trade Weathershield Stabilising Primer is a solvent based masonry primer specifically formulated to seal unstable areas of masonry that are still powdery and chalky after the surface has been thoroughly prepared for painting.

    For best results, make sure that surfaces to be painted are sound, clean and dry. All surfaces should be thoroughly scraped and brushed to remove any loose or flaking paint and dirt. Special precautions should be taken during surface preparation of pre- 1960s paint surfaces over wood and metal as they may contain harmful lead.

    A stiff fibre brush will give better results than a wire brush, as any wire that becomes embedded in the wall will rust, and stain the new paint. Carefully remove any organic growth or mould from the masonry, scraping and brushing again using a fibre brush. Do not inhale dust and wear a suitable face mask if dry sanding. The area should then be treated with Weathershield Multi-Surface Fungicidal Wash.

    Make good any surface imperfections using an appropriate filler. Larger holes and cracks should be filled with a sand and cement mix.


    Apply with a brush or roller only. Do not spray. Do no seal new or bare surfaces. Any areas that remain powdery and chalky after thorough prep should be sealed with a coat of Weathershield Stabilising Primer. When this coat is completely dry, apply 2 coats of Weathershield Masonry Paint.
