Woodwork Preparation & Painting in the Northern Suburbs

Why Proper Woodwork Preparation Matters

Beautifully painted doors, window frames and skirting boards can make a noticeable difference to the appearance of a home. However, achieving a smooth and durable enamel finish requires more than applying another coat of paint.

Woodwork often has old glossy coatings, worn edges, surface dents, peeling paint and small gaps between timber and adjacent walls. If these defects are not properly prepared, they can remain visible beneath the new finish or contribute to premature coating failure.

At Painters Cape Town, our 27 years of painting experience have established a preparation-first approach to interior and exterior woodwork. We use suitable Dulux primers and undercoats before applying the selected enamel finishing system.

Signs Your Painted Woodwork Needs Attention

• Peeling or flaking paint: the old coating has lost adhesion or deteriorated.
• Cracked paint along joints: movement between timber sections or adjoining materials may be affecting the finish.
• Exposed bare wood: areas where previous paint has worn away or detached.
• Yellowing enamel: certain older coatings may discolour over time.
• Rough or uneven surfaces: visible brush marks, old paint edges, dents or previous repair patches.
• Swollen or damaged timber: moisture may have entered vulnerable joints or exposed areas.
• Loose sealant around frames: deterioration may allow water entry or produce untidy finishing lines.
• Worn skirting boards: scuffs, scratches and damaged paint from cleaning, furniture or everyday use.

Most cosmetic defects can be assessed during a repainting quotation. However, rotten, severely swollen or structurally damaged timber may require carpentry repairs or replacement before painting.

The Woodwork We Prepare and Paint

Why Does Paint Peel From Wooden Surfaces?

Peeling enamel is not always caused by poor-quality finishing paint. In many cases, the condition of the underlying surface or previous coatings contributes to failure.

• Glossy old paint: insufficient sanding may prevent the next coating from bonding properly.
• Moisture in timber: trapped moisture can cause blistering, swelling and eventual peeling.
• Loose previous coatings: unstable paint cannot provide a reliable foundation for another coat.
• Contamination: grease, polish, wax and dirt can interfere with adhesion.
• Unprimed bare timber: exposed wood can absorb paint unevenly and may compromise the finish.
• Incorrect coating combinations: primer, undercoat and finishing paint must be suitable for one another and the existing surface.
• Weather exposure: sunlight and rain can gradually deteriorate exterior timber coatings.

This is why we do not assume that merely covering an old glossy finish with enamel will produce a durable result.

Our Woodwork Preparation and Painting Approach

Our written quotations specify the preparation required for the existing surface conditions. For suitable previously painted timber, our established Dulux painting approach includes the following:

This is our typical specification for suitable painted timber. New wood, existing varnish, heavily contaminated coatings, moisture-damaged timber and unusual substrates may require adjustments based on their actual condition and the applicable manufacturer guidance.

Why We Use Dulux Pearlglo Waterbased

Dulux Pearlglo Waterbased is a tough water-based enamel suitable for appropriately prepared interior and exterior surfaces, including woodwork.

We favour this finish on suitable projects for several practical reasons:

• Attractive mid-sheen appearance: produces a refined finish on doors, frames, skirting and trims.
• Smooth application characteristics: the paint’s flow and levelling help reduce visible application marks when applied correctly.
• Good resistance to yellowing: particularly useful for light-coloured interior woodwork.
• Suitable for interior and exterior use: offers flexibility across different painted timber components.
• Washable, durable finish: useful for frequently handled doors and trims.
• Water-based formulation: generally provides more convenient cleanup and lower solvent odour than traditional solvent-based enamels.

For exterior woodwork, its resistance to sunlight and weathering is another consideration when selecting a compatible coating system. Actual durability still depends on timber condition, exposure, preparation and maintenance.

Why We Use 100 mm Microfibre Rollers

Application technique is particularly important on doors, frames and skirting because imperfections are easily visible on smoother enamel finishes.

Our painters use 100 mm microfibre mini rollers on suitable flat woodwork surfaces to help achieve a fine, even coating with minimal roller texture.

Dulux Pearlglo Waterbased has favourable flow and levelling properties when applied correctly. This helps the freshly applied paint settle into a smoother finish, rather than retaining heavy brush or roller marks.

Brushes are still used where necessary for detailed profiles, edges, corners and other areas unsuitable for a roller.

Good results depend on applying the correct amount of paint, avoiding excessive reworking as the coating begins to dry and allowing the specified intervals between coats.

Why Woodwork Can Look Rough or Uneven After Painting

Customers sometimes expect a perfectly smooth finish from new enamel, even when the old timber surface has decades of paint build-up, dents or previous repairs.

A finishing coat does not automatically eliminate these imperfections.

• Old peeling-paint edges: may remain visible unless properly feathered during preparation.
• Sanding dust: can create a rough or gritty surface beneath enamel.
• Heavy brush marks: may show through when an unsuitable application technique is used.
• Uneven absorption: may affect the appearance of exposed or repaired timber without suitable priming.
• Previous paint build-up: thick historical coating layers can affect the appearance of profiles and corners.
• Timber grain and defects: the original substrate influences the finished appearance.

Our preparation aims to improve the existing woodwork and achieve a consistent painted finish within the agreed scope. It does not mean every older wooden surface can be made identical to newly manufactured joinery.

Painting Previously Varnished Woodwork

Previously varnished or stained timber requires particular attention before changing to a painted enamel finish.

Glossy varnish may prevent subsequent paint from adhering properly if the surface has not been adequately prepared. Old waxes, polish and other contaminants can cause further difficulties.

Depending on the condition and existing finish, additional cleaning, sanding and a suitable adhesion-promoting primer or undercoat system may be required.

Our approach is to evaluate the existing finish rather than assume that the ordinary previously painted timber specification can be applied unchanged.

Interior and Exterior Woodwork Have Different Exposure Conditions

Interior doors, door frames and skirting are normally affected by handling, cleaning, furniture contact and general wear.

Exterior wooden windows and doors face additional exposure to sunlight, temperature changes and rainfall. Water can enter around deteriorated joints, exposed end grain or defective sealants.

In Durbanville, Bellville, Brackenfell, Plattekloof and Kuils River, strong summer sunshine and winter rain can contribute to coating deterioration on exposed timber.

We therefore pay particular attention to the condition of exterior woodwork before repainting. Where moisture damage or defective seals are present, the causes should be addressed rather than merely concealed with new enamel.

Professional Advice for Maintaining Painted Woodwork

• Attend to peeling paint early: prolonged exposure of bare exterior timber can increase preparation and repair requirements.
• Watch for moisture damage: swelling, softness or recurrent blistering can indicate underlying problems.
• Avoid painting over glossy finishes without preparation: existing coatings need a suitable surface key.
• Check window and door sealants: failed perimeter joints may allow moisture entry.
• Do not ignore deteriorated timber: severely rotten sections require appropriate repair or replacement.
• Use suitable paint systems: bare wood primer, undercoat and finishing enamel each serve a distinct purpose.
• Maintain painted surfaces: gentle cleaning and timely attention to scratches or exposed wood can help preserve the finish.
