Sure Seal Timber Sealer is a high-performance penetrating sealer, designed for long-lasting protection of timber surfaces. Its quick-drying and easy-to-apply nature makes it a user-friendly choice for all your timber needs. The deep-penetrating formula creates a clear, natural, and hydrophobic finish on both raw and stained timber. This protects against water and oil-based staining, as well as leaching, ensuring your timber maintains its integrity.

Colour Accuracy Disclaimer: We have taken care to display the most accurate visuals of our products. However, we are not responsible for the colour accuracy of the device you are viewing our swatches on. These variations arise due to different computer monitors and devices (make, model and technology, as well as resolution, contrast and brightness control settings) in much the same way a scan will differ from an original image and a colour photocopy. Furthermore, coatings can exhibit variation in perceived colour depending on gloss level and application method. If you require a very specific colour match, please make your selection via actual swatches and colour boards available at our showroom.

Product Disclaimer: Ensure you read all product, technical and safety data sheets prior to application as liability falls on the applicator. All products must be applied in accordance with manufacturer’s recommended method.
