Few things are more frustrating than seeing your freshly painted walls begin to peel, crack, or bubble. Fortunately, these problems are avoidable with the right prep, product, and application. In this FAQ guide, we’ll walk you through how to prevent paint from peeling or cracking — and ensure your finish lasts beautifully for years to come.
1. Start with a Clean Surface
Dust, dirt, grease, or mildew will interfere with paint adhesion.
Before you paint, clean all surfaces thoroughly with a mild detergent and water. For kitchens or bathrooms, degreasing is essential.
Pro Tip: Use a TSP substitute or professional-grade cleaner from our collections for optimal results.
2. Repair & Sand Any Imperfections
Cracks, holes, or peeling areas must be patched and sanded before painting.
If you paint over existing peeling areas, the problem will only worsen.
Use a filler or patching compound
Let it dry completely
Sand smooth and dust off
3. Prime When Necessary
Primer provides a stable surface for paint to grip. It also prevents stain bleed-through and improves longevity.
You must use primer if:
You’re painting over bare drywall or wood
You're changing from dark to light colours
You're painting a previously glossy or stained surface

4. Paint in Proper Conditions
Paint doesn't like extremes.
Ideal temperature: 10°C to 30°C (50°F to 85°F)
Avoid humid, rainy, or freezing weather (especially for exterior work)
Ensure indoor areas are ventilated and dry
Paint applied in poor conditions may dry too quickly or improperly, leading to cracks or bubbles.
5. Choose Quality Paints
Low-quality or expired paint is a leading cause of peeling and cracking.

6. Don’t Skip Drying Times
Each coat of paint must dry properly before the next is applied.
If you rush this process, paint layers won’t bond, leading to cracking or peeling.
Check the label, but a safe rule of thumb is:
2 to 4 hours between coats for most interior paints
Longer in cooler or more humid conditions
7. Apply the Paint Properly
Avoid applying paint too thickly, which can cause surface tension cracks.
Use the correct tools (brush, roller, or sprayer), and follow these basics:
Use even strokes
Don’t overload the brush or roller
Always follow the grain or texture of the surface
