Product Information
Full details
This HQC PAINTS Stabilising Primer in a 10L container is designed for DIY enthusiasts and professional painters preparing old, powdery, or chalky walls for a fresh coat of HQC Masonry Paint. Its key benefit is creating a stable, uniform surface that ensures optimal adhesion and finish for your topcoat, preventing future flaking or peeling. A potential caveat is that it requires thorough surface preparation beforehand to be most effective. Key features include its water-based formulation, suitability for a wide range of masonry surfaces, and its role in sealing powdery areas.

FAQs
What types of surfaces can I use this primer on?
You can use it on brick, stone, render, concrete, plaster, pebble dash, stucco, and existing painted surfaces. It's also suitable for friable surfaces prior to over-coating.
How do I prepare the surface before applying the primer?
The surface must be sound, clean, and dry. Remove all loose paint, dirt, and efflorescence. Any areas that remain powdery or dusty after preparation should then be sealed with the primer.
What is the drying time for the HQC Stabilising Primer?
Drying times can vary based on conditions, but it typically needs to be fully dry before applying subsequent coats of paint. Refer to the product packaging for specific drying time recommendations.
Can I paint over this primer with any type of paint?
While it is specially formulated for HQC Masonry Paints for best results, it can be used to seal surfaces for over-coating. However, optimal performance and adhesion are guaranteed with HQC Masonry Paints.
Does the primer change the colour of the surface?
No, the HQC Stabilising Primer is colourless and dries clear, so it will not affect the final colour of your chosen masonry paint.
How should I clean my tools after using the primer?
Clean brushes, rollers, and any other equipment with water immediately after use while the product is still wet.
Is this primer suitable for very damp walls?
This primer is designed to seal powdery and chalky surfaces once they are dry. It is not a waterproofing solution and should not be applied to actively damp or wet walls. Address any underlying damp issues first.
Troubleshooting
Primer is not binding powdery surface
Ensure the surface was thoroughly prepared and all loose material was removed before application. Multiple thin coats may be necessary on very powdery surfaces, allowing each to dry fully.
Paint is peeling or flaking after application
The primer may not have been fully dry before painting, or the underlying surface may still have issues not addressed by the primer. Ensure adequate drying time and re-evaluate surface preparation.
Primer leaves a sheen or is difficult to over-coat
Ensure the primer is fully dry. If a slight sheen remains, a light sanding might be beneficial before applying the topcoat, though typically it dries to a matte finish.
