Sealers & Stabilisers

Painting Sealers & Stabiliser for Reliable Surface Prep

Proper surface preparation is essential for achieving a flawless finish — and that’s where our painting sealers and stabilising solution come in. Whether you're dealing with powdery walls, porous render, or uneven masonry, choosing the right primer sealer paint helps create a uniform base and improves coating adhesion.

Whether you're dealing with powdery walls, porous render, chalky facades, or uneven masonry, choosing the right primer sealer helps create a uniform base, reduces absorption, and improves overall material adhesion. This not only enhances the durability of the top layer but also minimises the risk of peeling, flaking, or patchy results over time.

Exterior Paint Stabiliser for Problematic Surfaces

If you're working outdoors, a high-quality exterior stabiliser is a must. It penetrates unstable surfaces, seals chalky render, and prevents future peeling. Our Peel Stop Clear Binding Primer is a popular choice for binding flaking coatings without sanding.

Use a masonry paint stabiliser to strengthen dusty or loose surfaces and help the paint last longer. For badly weathered areas, choose a stabiliser made specifically for masonry to ensure an even finish and lasting results.

These solutions are especially useful on older buildings where surface degradation has already begun. By reinforcing the outer layer, they create a sound foundation for subsequent coatings and minimise the risk of blistering, uneven absorption, or premature failure. Whether working on residential façades or commercial units, applying a stabiliser helps extend the life of your finish while reducing maintenance in the long term.

Interior Paint Stabiliser Options

Even indoor walls benefit from sealing — particularly over old filler, plaster, or stained surfaces. An interior stabilising solution provides moisture resistance, evens out porosity, and reduces product absorption. Juno Hidrocril Solvent-Free Acrylic Sealer works well on multiple interior surfaces.

Using a stabilising base indoors helps achieve smoother application, especially when transitioning between different wall materials or repairing previous damage. It also prevents uneven sheen and helps the finishing layers maintain their colour and texture over time. In high-humidity areas like kitchens or bathrooms, a proper sealer can significantly enhance durability and protect against future issues such as flaking or discolouration.

Primer Sealer: When to Use It

Choosing the right primer sealer paint depends on the material and condition of your surface:

• Use on bare plaster, cement, or aged substrates.
  
• Ideal where peeling, chalking, or efflorescence is present.
  
• Great as a base layer before breathable or water-based coatings.

These sealers also minimise the number of finishing coats required, saving time and effort.
