If you’ve ever wondered whether you really need primer before painting, you’re not alone. Many homeowners skip this step to save time—only to regret it when their fresh paint starts peeling, streaking, or letting stains show through. Here’s a practical guide to understanding primer and when it’s worth the extra effort.
1. What is primer, and why is it important?
Primer is a preparatory coating applied before paint. It:
- Helps paint stick to the surface
- Creates a smooth, even base
- Blocks stains and colour bleed
- Extends the life of your paint job
Think of it as the foundation for a flawless finish—without it, even the best paint can fail.
2. When should I use primer?
Primer is essential in these situations:
-
New drywall – Seals the porous surface
-
Covering dark colours – Reduces the number of topcoats
-
Painting over glossy finishes – Improves adhesion
-
Stained or damaged walls – Blocks water, smoke, or tannin stains
- Bare wood or metal – Prevents warping or rust
You’ll find primers for every surface in our paint collection.
3. Are there different types of primer?
Yes, and the right one depends on your project:
-
Latex primer – Low-odour, great for drywall and softwoods
-
Oil-based primer – Strong adhesion and stain blocking
- Shellac-based primer – Excellent for sealing odours and heavy stains
Our services team can match the right formula to your needs.
4. Can primer be tinted?
Yes! Tinting primer close to your final colour:
- Improves coverage
- Reduces the number of topcoats
- Enhances colour accuracy
This is especially useful for bold colour changes.
5. What happens if I skip primer?
Without primer, you risk:
- Uneven sheen
- Paint peeling or chipping early
- Stains bleeding through
- Needing extra coats (and more paint) to cover the surface
6. Is “paint-and-primer-in-one” the same thing?
Not exactly. While these products work for repainting similar colours, they can’t replace a dedicated primer when you need strong stain blocking or maximum adhesion.
7. How do I know if my surface needs primer?
A quick test: Apply painter’s tape to the surface, press firmly, and rip it off. If paint or surface material comes away, you need primer.
