Product Overview:

Sikkens Cetol Filter 7 Plus 2.5L is a premium, solvent-borne, medium-build woodstain designed to provide exceptional protection and a long-lasting, decorative satin finish for exterior timber surfaces. As part of the renowned Sikkens woodcare system, this product is formulated to safeguard timber against weathering, UV degradation, and moisture-related damage, while enhancing the wood’s natural grain and tone.

Ideal for both hardwood and softwood joinery such as windows, doors, conservatories, and cladding, Cetol Filter 7 Plus forms a microporous, flexible film that allows wood to breathe while repelling rain and resisting cracking and flaking. Its advanced formulation includes UV-absorbing pigments that offer superior protection against sunlight and help maintain the vibrancy of the colour over time.

Key Features & Benefits:

• Medium-build satin finish: Creates a luxurious, translucent satin sheen that highlights wood grain while offering robust protection.

• Outstanding UV protection: Contains transparent iron oxide pigments that filter out harmful UV rays, preventing premature greying and weathering.

• Highly durable: Offers long-lasting performance even in exposed conditions; reduces the frequency of maintenance cycles.

• Microporous formula: Allows moisture vapour to escape from the wood, reducing the risk of blistering and peeling.

• Flexible finish: Expands and contracts with the wood, ensuring lasting adhesion without cracking or flaking.

• Part of a system: Designed to be applied as a topcoat over Sikkens Cetol HLS Plus base stain for maximum protection and depth of colour.

• Solvent-borne for deep penetration: Provides excellent adhesion and deep wood nourishment.

Recommended Uses:

• Exterior hardwood and softwood joinery
