Product Overview:

Sikkens Cetol Filter 7 Plus 5L is a high-performance, solvent-borne, medium-build exterior woodstain that delivers exceptional durability, UV protection, and long-term weather resistance. Specially formulated for use on exterior softwood and hardwood joinery, this product is ideal for timber windows, doors, cladding, and trims that require a satin, translucent finish while retaining the natural beauty of the wood grain.

The woodstain is enriched with transparent iron oxide pigments that help to maintain the integrity of the substrate by filtering out harmful UV rays and preventing premature weathering, cracking, and peeling. When combined with a compatible base coat like Sikkens Cetol HLS Plus, this system provides one of the longest-lasting finishes available for exterior wood protection.

Key Features and Benefits:

✔ Superior UV Protection

Formulated with transparent UV-absorbing pigments, it protects timber from the damaging effects of sunlight, reducing discolouration and degradation over time.

✔ Durable Satin Finish

Medium-build finish that highlights the natural grain and texture of the timber. Provides a refined, low-sheen satin appearance that is both beautiful and functional.

✔ Enhanced Weather Resistance

Resists rain, frost, temperature extremes, and fluctuating moisture levels to maintain long-lasting protection and aesthetic appeal.

✔ Microporous and Flexible Film

Allows moisture vapour to escape from the timber substrate while preventing water ingress. The finish moves with the timber to reduce the risk of flaking or blistering.

✔ Long-Term Maintenance Cycle

Typically requires maintenance every 3 to 5 years depending on exposure, reducing the need for frequent recoating and lowering lifetime costs.

✔ Solvent-Based for Deep Penetration

Solvent-borne formula enhances adhesion and performance on timber, especially in high-exposure areas.

Recommended Applications:

• Exterior softwood and hardwood joinery

• Timber windows and window frames
