How to stop paint chipping off your Bannister and wood work.

One of the most common questions we're asked at Pure Perfection Painters is:
"Why is my new paint chipping off my skirting boards, doors or bannister?"
It's an incredibly common problem, especially as more people switch from traditional oil-based gloss paints to modern water-based alternatives.
The good news is that it can be avoided. The bad news is that once the paint starts peeling or flaking, fixing it usually involves a lot of sanding and repainting.
In this guide, we'll explain why it happens, how to identify the problem before you start decorating, and the simple steps that will ensure your woodwork has a durable, professional finish.
Why Does Water-Based Paint Chip Off Woodwork?
The biggest cause of paint failure is applying modern water-based paint directly over old oil-based gloss.
Many homeowners assume they can buy a tin of water-based wood paint and paint straight over existing gloss. Unfortunately, it isn't that simple.
Water-based paints don't naturally bond well to old oil-based coatings. Without the correct preparation, the new paint sits on the surface rather than adhering properly. It may look perfect initially, but over time you'll notice:
Paint scratching easily
Chipping around edges
Flaking on bannisters and handrails
Peeling on doors and skirting boards
Areas that receive frequent contact, such as bannisters, door frames and skirting boards, are usually the first places where the problem appears.
Repairing failed paintwork can be extremely time-consuming, so it's always worth preparing the surface correctly from the beginning.
How to Tell if Your Existing Paint is Oil-Based
Fortunately, there are two simple ways to check.
1. Look at the Existing Finish
Older gloss paints usually develop a noticeable yellow tint over time. If your skirting boards, doors or bannister have yellowed, there's a good chance they're coated in traditional oil-based gloss.
2. Carry Out a Simple Adhesion Test
If you're unsure, test a small area before decorating.
Paint a section approximately 3cm square using your chosen water-based paint.
Leave it to dry overnight.
The following day, use your fingernail to scratch the painted area.
If the paint scratches off easily, it hasn't bonded correctly. This means you'll need to use a suitable primer before applying your finishing coats.
This simple test can save hours of preparation later.
The Correct Way to Paint Over Oil-Based Gloss
Step 1 - Sand the Surface
Begin by lightly sanding all of the woodwork.
This removes minor imperfections while creating a slightly rough surface that helps the primer grip more effectively.
A small electric orbital sander makes this job much quicker, especially if you're decorating multiple doors, skirting boards or bannisters.
Once you've finished sanding, remove all dust using a vacuum and a damp cloth.
Step 2 - Apply a High-Quality Bonding Primer
This is the step that many DIY decorators skip, but it's the key to achieving a long-lasting finish.
A quality primer creates a strong bond between the old oil-based paint and your new water-based topcoat.
Our preferred products are:
Johnstone's Trade Joncryl Primer – excellent adhesion with built-in stain blocking.
Zinsser BIN Aqua – another outstanding water-based primer that's easy to apply and provides excellent adhesion.
One coat is normally all that's required.
If you're ever unsure what type of paint is already on the woodwork, applying a suitable primer removes the guesswork and gives you the best possible foundation.
Our Recommended Wood Paint
Once the primer has fully dried, it's time to apply your finishing coats.
At Pure Perfection Painters, our preferred choice is Johnstone's Trade Aqua Guard Satin.
It consistently delivers excellent results because it:
Produces a durable, hard-wearing finish.
Resists scratches and everyday knocks.
Doesn't yellow over time.
Flows beautifully for a smooth professional finish.
Is ideal for high-traffic areas such as doors, skirting boards and bannisters.
Apply two full coats directly over the primer.
There's no need to sand the primer beforehand unless you notice imperfections that need removing.
Most homeowners now choose a satin finish rather than traditional gloss, as it provides a modern appearance while remaining extremely durable.
Why Preparation Makes All the Difference
Professional decorators know that preparation accounts for most of the work.
Using the correct primer dramatically improves adhesion, while choosing a premium trade paint provides the durability needed for busy family homes.
The result is woodwork that:
Won't chip easily
Resists everyday wear and tear
Stays white without yellowing
Looks freshly painted for years
Taking a little extra time before opening the paint tin can save countless hours of repairs in the future.
