Full details
The Dulux Trade Alkali Resisting Primer is a solvent-based primer designed for interior and exterior masonry surfaces, including plaster, that may be subject to alkalinity. Its key benefit is its ability to effectively seal fresh, alkaline surfaces and block tough stains like nicotine and fire damage, ensuring a better finish for your topcoat.

FAQs
Can this primer be used on wood?
This primer is specifically designed for masonry and plaster surfaces. It is not recommended for use on bare wood. For wood, a different type of primer would be more suitable.
How long does it take for the primer to be recoatable?
The primer is recoatable between 16 and 24 hours after application. This time can vary depending on ambient temperature and humidity.
Can I spray this primer?
No, for health and safety reasons related to solvent-based paints, spray application is not recommended. It should be applied by brush only.
What is the coverage rate of this primer?
The primer provides coverage of up to 9 square meters per litre, depending on the surface porosity and texture.
Is this primer suitable for bathrooms?
Yes, it is suitable for interior use in areas like bathrooms, bedrooms, hallways, kitchens, and living rooms, provided it is used as a primer base for an appropriate topcoat system.
How do I clean my brushes after using this primer?
After use, remove as much paint as possible from brushes before cleaning them with a suitable brush cleaner.
What surfaces can this primer be used on?
It is particularly suitable for interior and exterior masonry surfaces, including plaster, that may contain alkalis. It also works on fire-damaged surfaces and those treated with fire retardant chemicals.
Do I need to thin the primer?
Stir thoroughly before use. Thinning is generally not required if applied correctly. If thinning is necessary, use White Spirit at a 10:1 ratio.
Troubleshooting
Primer not adhering well to the surface
Ensure the surface was properly prepared, clean, dry, and free from dust or contaminants before application. Check for excessive alkalinity if the surface is new plaster.
Stains are still visible after priming
Ensure a full, even coat of primer was applied, covering the entire stained area. For severe stains, a second coat of primer may be necessary, or the stain may require specific pre-treatment.
Primer drying too slowly
Ensure application is within the recommended temperature range and humidity levels. Avoid applying in damp or cold conditions. Ensure adequate ventilation.
Strong solvent odour persists after drying
Ensure adequate ventilation is maintained during and after application. The odour should dissipate over time as the paint fully cures. If the odour is excessive and persistent, check the product data sheet for VOC information and ensure no other issues are present.

Setup, Compatibility & Care
Preparation is Key: Before application, ensure surfaces are sound, clean, and dry. For new surfaces, full drying is crucial. Refer to the Dulux Trade Datasheet 301 for detailed surface preparation guidelines. Always read Health & Safety information regarding old lead paints if applicable.
Application: This primer is designed for brush application only. For health and safety reasons associated with solvent-based paints, spray application is strongly discouraged. Stir the product thoroughly before use.
Coats: Apply one coat of the primer to bare or stained surfaces. This is typically sufficient before applying your chosen Dulux Trade finish.
Thinning: If thinning is required, use White Spirit at a ratio of 10 parts White Spirit to the primer. However, for most applications, thinning is not necessary if applied correctly.
Drying & Recoating: Allow 6-10 hours for drying. The surface is ready for recoating between 16-24 hours after application, depending on temperature and humidity.
Tool Cleaning: After use, remove as much paint as possible from brushes before cleaning them with a suitable brush cleaner.
Storage: Store the primer in a cool, dry place, away from direct sunlight. Do not use or store in extreme temperatures, and protect from frost.
Compatibility: Suitable for use on interior and exterior masonry, plaster, and surfaces previously treated with fire retardant chemicals. Always finish with an appropriate Dulux Trade paint system.
