Wood Varnishing Pretoria: sanding, sealing and refinishing timber. The finish already on the wood decides what can go over it, so the first job is checking what is there.

Get the Best QuoteTimber Commonly Varnished or Sealed
- Front doors and garage doors. Solid timber exposed to sun.
- Window frames. Timber frames and sills.
- Decks. Pool decks, patios and walkways.
- Pergolas, carports and lapas. Poles, beams and slats.
- Interior timber. Staircases, handrails, ceilings and built-in cupboards.
- Fascias and barge boards. Timber trims on the roof line.
Assessing the Existing Finish
- Varnish. A film on top of the wood. Once it peels, it has to be sanded off.
- Penetrating sealer or oil. Soaks in and can be recoated after cleaning.
- Paint. Stripping painted timber back to bare wood takes much longer.
- Grey or cracked wood. UV-damaged timber needs sanding back to sound wood.
- Rot. Soft wood is cut out and replaced before finishing.
Choosing a Finish
- Exterior varnish. A glossy film. Looks good but needs regular maintenance in full sun.
- Penetrating sealer. Easier to maintain on decks and pergolas.
- Decking oil. Suits hardwood decks and needs regular reapplication.
- Interior varnish. Hard-wearing for stairs, floors and furniture.
Preparation and Application
- Clean the timber and let it dry.
- Sand off failing varnish and grey surface fibres.
- Repair or replace rotten sections.
- Apply the first coat thinned if the product requires it.
- Lightly sand between coats where the product requires it.
- Apply further coats as the product specifies.

Pretoria Conditions to Plan For
Strong sun at Pretoria's altitude breaks down exterior varnish quickly, especially on north- and west-facing doors and decks. Many owners in the area choose penetrating sealers for outside timber because they can be refreshed without sanding back to bare wood. Varnish should go on in dry weather, away from summer afternoon storms.

How often should outside timber be resealed?
It depends on the product and sun exposure. Exposed decks and doors often need maintenance coats more often than shaded timber. Ask for the product's recommended interval.
Can you varnish over old varnish?
Only if it is sound and well bonded, after a light sanding. Peeling varnish has to be removed first.
Is varnish or sealer better for a deck?
Many contractors prefer penetrating sealers or oils on decks because film-forming varnish wears and peels under foot traffic.
Can painted wood be varnished?
Only after the paint is stripped to bare wood, which adds time and cost. Ask for this as a separate line item.
