V-Coat: The Ultimate Oil-Based Wood Treatment for South African Wooden Doors & Windows
Wooden doors and windows add warmth, beauty, and long-lasting value to any South African home. But without the right wood oil and wood treatment, exterior wood can quickly be damaged by sun, rain, and UV exposure. That’s why Van Acht developed V-Coat, a premium oil-based wood sealer explicitly engineered for our wooden products and our climate.
As the leaders in wooden doors and windows, Van Acht created V-Coat because generic hardware-store products weren’t good enough. No other sealer is tailored to the needs of high-quality exterior wood in South Africa.

Why V-Coat Is Better Than Other Wood Oils and Sealers
V-Coat is not a generic product. It was designed by Van Acht to protect the exact hardwoods used in our windows and doors. Through decades of research and hands-on testing, we developed a deep-penetrating oil that outperforms standard wood treatments.
V-Coat offers unmatched protection:
✔ Deep oil penetration for long-lasting nourishment
✔ Exceptional UV and sun protection
✔ Strong water resistance to prevent wood rot
✔ Algae and moisture defence
✔ A breathable finish (never traps water)
✔ Enhanced wood grain and colour
This is science-backed wood protection made for South African weather.

Oil-Based vs Water-Based Wood Treatments
Many homeowners wonder whether to use oil-based or water-based products. The truth is clear:
Oil-based wood treatments protect better because they:
Penetrate deeper into the wood fibres
Resist UV breakdown far more effectively
Do not wash off easily in rain or humidity
Keep wood flexible rather than brittle
Last longer, reducing maintenance
Enhance the natural grain with a richer finish
Water-based sealers sit on the surface and break down quickly.
For exterior wood care, oil-based always wins—and V-Coat leads the category.

Never Use Varnish on Exterior Wood — Here’s Why
Varnish may look shiny at first, but it is one of the worst choices for exterior wooden windows and doors.
Varnish:
❌ Cracks and peels from the South African sun
❌ Traps moisture and accelerates hidden rot
❌ Requires sanding or stripping to maintain
❌ Offers poor UV protection
❌ It is not breathable
V-Coat, by contrast, penetrates, nourishes, and protects—never trapping moisture and never turning brittle.
V-Coat Colours — With Walnut as the Most Popular Choice
V-Coat is available in a curated range of rich, natural colours that enhance and protect exterior wood:
Clear – natural, raw-wood appearance
Golden Brown – warm and classic
Kiaat – refined African tone
Mahogany – rich, elegant red-brown
Teak – timeless and traditional
Walnut – luxurious, and the most popular V-Coat colour among South African homeowners
Homeowners love Walnut because it offers a bold, premium finish that hides minor imperfections, enriches grain patterns, and pairs beautifully with contemporary and traditional architecture.

How Often Should You Treat Your Wood?
Exterior wood requires consistent care for maximum lifespan.
For the best protection, apply V-Coat:
Every 6–12 months, depending on exposure
More frequently for north-facing, coastal, or high-sun areas
As soon as wood looks dry, dull, faded, or weathered
A small maintenance routine prevents costly replacements.
How to Apply V-Coat (Fast, Simple, Effective)
Clean the wood thoroughly
Apply V-Coat with a brush or cloth
Allow it to absorb
Apply a second coat if the wood is very dry
No sanding required unless the wood is already severely weathered.
Why Van Acht Developed V-Coat
As Africa’s leading manufacturer of wooden doors and windows, Van Acht saw that customers needed a purpose-built, high-performance wood oil—not a “one product fits all” approach.
V-Coat was formulated to protect the exact wood species we manufacture daily, ensuring unmatched performance and peace of mind.
This is why V-Coat is the most trusted wood treatment for exterior joinery in South Africa.
