Wood Sealers
Specialist wood sealers provide long-lasting protection for timber surfaces, shielding them from moisture, sunlight, and daily wear. Suitable for both interior and exterior use, they are commonly applied to wooden decking, floors, outdoor furniture, and structural joinery. For those treating outdoor features, wood sealers work especially well alongside durable decking paint to resist footfall and weathering. Around the home, sealing timber before using door paints or fence paint adds further resilience to boundaries, frames, trims, and entranceways. These help prevent flaking, splitting, or rot, offering dependable protection across a wide range of wooden surfaces.

Wood Sealers
Preserving wooden surfaces requires more than just aesthetic care; it demands durable, long-lasting protection against environmental factors. Specialist wood sealers are formulated to address the unique challenges posed by moisture, UV exposure, and daily wear, offering comprehensive protection while enhancing the natural characteristics of the wood.
These sealers work by deeply penetrating the wood fibres, creating a resilient barrier that helps prevent warping, cracking, and decay. This is particularly important for outdoor wooden structures like decking, fences, and garden furniture that face continuous exposure to the elements. The UV protection included in these products helps maintain the wood’s vibrant appearance, reducing the risk of fading even under strong sunlight.
Wood sealers are also invaluable indoors, especially in high-traffic areas like floors and staircases. Their resistance to stains, dirt, and fungi makes maintenance straightforward, while their robust formulation ensures that treated surfaces withstand everyday use without losing their appeal. By choosing specialist wood sealers, you invest in the longevity of your wooden structures, keeping them looking great and performing well for years to come.
Wood Sealers FAQs
What is the purpose of using a wood sealer?
A wood sealer protects wooden surfaces from moisture, UV light, and wear. It penetrates the wood fibres to create a durable, water-resistant barrier that prevents cracking, warping, and decay.
Can wood sealers be used on both hardwoods and softwoods?
Yes, specialist wood sealers are suitable for a wide range of wood types, including both hardwoods like oak and softwoods like pine. Always check the product specifications to ensure compatibility.
Do wood sealers prevent UV damage?
Yes, most specialist wood sealers contain UV inhibitors that help protect the wood from sun damage, maintaining its natural colour and reducing the risk of fading.
Can I apply wood sealer over stained wood?
Yes, many wood sealers can be applied over stained or finished wood as long as the stain has fully cured. This combination offers both aesthetic appeal and enhanced protection.
How often should I reapply wood sealer?
The frequency of reapplication depends on the level of exposure and the specific product used. Generally, outdoor wood surfaces may require resealing every 1-3 years, while indoor applications can last longer.
