Paintmaster’s Stabilising Primer is a solvent-based primer which is clear in colour and is easy to apply to all kinds of surfaces. This solution has been formulated to seal all kinds of unstable areas which remain powdery and chalky after the surface has been prepared for painting.

This primer can be used to stabilise practically any surface before the application of Paintmaster’s Masonry Paint. Not only can this primer create a more even area for the paint’s application, it can also provide some protective benefits for the surface itself.

Designed for use on a variety of surfaces, including masonry, plaster, and concrete, our stabilising primer offers superior coverage, penetration, and long-lasting performance, making it the perfect choice for both interior and exterior projects.


  1. Porous Surface Sealing: Our Stabilising Primer is specifically formulated to penetrate and seal porous surfaces, including masonry, plaster, brick, and concrete. By sealing the surface, our primer prevents excessive absorption of subsequent coats of paint, ensuring uniform coverage and adhesion for a flawless finish.
  2. Enhanced Adhesion: Engineered for superior adhesion, our stabilising primer promotes strong bonding between the substrate and the topcoat, ensuring long-lasting durability and performance. Whether applied to new or previously painted surfaces, our primer forms a stable foundation that enhances the effectiveness and longevity of your paint job.
  3. Stain Blocking: Our Stabilising Primer effectively blocks stains and discoloration caused by water damage, efflorescence, rust, and other common surface contaminants. By sealing stains and preventing them from bleeding through, our primer ensures a clean and professional-looking finish that enhances the overall appearance of your surfaces.
  4. Mildew Resistance: Formulated with mildew-resistant additives, our stabilising primer helps prevent the growth of mould and mildew on interior and exterior surfaces, ensuring a healthier and more hygienic environment. With its mould-resistant properties, our primer provides long-lasting protection against unsightly and potentially harmful fungal growth.
  5. Versatile Application: Suitable for both interior and exterior use, our Stabilising Primer is ideal for a wide range of projects, including walls, ceilings, facades, and masonry structures. Whether you’re painting a new construction or renovating an existing surface, our primer provides reliable adhesion and protection for diverse applications.
  6. Easy Application: Designed for hassle-free use, our Stabilising Primer features a smooth, creamy consistency that applies easily with a paint brush, paint roller, or sprayer. Whether you’re a professional contractor or a DIY enthusiast, our primer offers excellent flow and coverage, resulting in a professional-quality finish every time.
