Pro tips
Pygmalion tip: In Belgian homes, residual moisture after wallpaper removal remains a frequent challenge, particularly in poorly ventilated rooms. Apply Stop Primer even if stains appear light: its preventive fungicidal action will avoid unpleasant surprises months after finishing. On old glossy paints or varnished woodwork, degreasing followed by light sanding with 120-grit paper guarantees perfect adhesion. Always wait for complete drying before filling, especially during humid periods: touch the surface, it must be perfectly dry to the touch and show no moisture feeling.
FAQ
Does this primer really block all stains?
Yes, Stop Primer acts as an effective isolating barrier against common stains (nicotine, water, mould) and prevents their reappearance through the topcoat paint. It also covers residual traces of micro-organisms after treatment.
Can I use it directly on existing mould?
Stop Primer contains fungicidal agents that kill moulds, fungi and bacteria present on the surface. It also prevents their reappearance on the paint film. However, it is recommended to clean heavily contaminated surfaces before application.
How long should I wait before applying the topcoat?
Allow the primer to dry completely before applying the next coat. Drying time varies depending on temperature, ambient humidity and ventilation. Consult the manufacturer's instructions for precise timeframes suited to your project.
Can it be applied on metal or already painted surfaces?
Yes, Stop Primer adheres perfectly to metal, wood, painted or varnished surfaces, and all smooth non-porous substrates. It is specifically designed to improve adhesion on these difficult surfaces.
Do I need to dilute the product before application?
No, dilution is not recommended. Stop Primer must be applied as supplied to guarantee its maximum effectiveness as an isolating barrier and fungicide.
