FAQ
What type of walls are these paints best suited for?
These paints work particularly well on plaster walls and drywall that have developed cracks due to settling or age. They're less ideal for heavily textured surfaces as the paint may not achieve a consistent finish.
Do I need to prime the wall before using this paint?
Priming is highly recommended, especially on new or previously unpainted walls. A primer creates a stable surface for the repair paint and helps ensure better adhesion and colour consistency.
What size cracks can I realistically repair with these products?
This range is best suited for hairline cracks and small gaps up to approximately 5mm wide. Larger fissures may require specialist patching compounds or filler before applying a decorative finish.
How many coats should I apply?
Typically, two coats are recommended for optimal coverage and durability. Allow each coat to dry completely according to the manufacturer’s instructions before applying the next.
Are these paints easy to clean up?
Most of these paints can be cleaned with water, but always refer to the specific product's instructions for detailed cleaning recommendations to avoid damaging the paint.
Do I need a special applicator tool?
While taping applicators are useful for precision work, you can also use standard paintbrushes or rollers. A putty knife is essential for applying and smoothing out the repair compound before painting.
Can I colour match existing wall paint?
Many of these paints include tinting options to allow you to closely match your existing wall colour. Carefully test the paint on a small, inconspicuous area first.
How long does it take for the repair paint to dry?
Drying times vary depending on the product and environmental conditions but generally range from 4-8 hours between coats and 24 hours before applying further decoration.
What is the shelf life of these paints?
Check the individual product packaging for specific expiry dates. Once opened, it’s recommended to store paints in a cool, dry place away from direct sunlight.
Are there any additives that improve crack filling performance?
Some formulations include thickening agents or polymers designed to enhance adhesion and prevent further cracking by creating a flexible barrier against moisture.
