How to Renovate Your Decking or Patio

Refurbish My Decking


What type of wood is used for Decking?

The most common types of decking boards are pressure treated softwoods which are derived from confiners such as firs, pines and larch. Around 80% of timber for buildings derives from softwoods as they are economic, lighter and used in decking, patios, cladding, buildings, fencing and garden rooms. Decking boards made from softwoods are often impregnated with oils at the manufacturers to improve performance in storage.

However, installed and exposed through the winter months, this type of timber may deteriorate with mould and moss spreading across damp areas. If the wood is left untreated it will result in rotting and long-term damage.


Paints vs Stains

Paints and stains are used to protect, preserve and decorate timber but they function in different ways. The main difference between paint and stain is that paint will form a hard layer over the timber which offers protection from mechanical impact and abrasion, whereas stains are used to penetrate the wood deeply to highlight the grain, intensify the wood tones and change its appearance.

The quality of stains can vary dramatically with many cheap products on the market heavily discounted by major retailers. These are formulated to a low price, they have reduced volume solids and a higher water content, resulting in lower performance. These low-cost products quickly fade and require re-staining every year.

More effective treatments for exterior wood are available, developed in Norway for extreme conditions known as Terrace Glaze, these are water-based alkyd oils which have high penetrating and water repellent properties. They are pigmented with exterior durable pigments which help it retain its appearance for years. Agents are also added to protect against mould and algae. Terrace Glaze is the latest addition to the Demidekk range known as Demidekk Terrasslasyr which is the Norwegian translation, it requires only one coat and will not require repainting for three years. Developed in Norway to protect exterior wood on patios, decking and balconies in the most harsh of conditions.


How to Renovate Previously Stained Patios and Decks

To achieve the best results, the old stain should be removed, this is also the case if the decking has been oil impregnated. Before applying the product, make sure that the decking is clean, and any loose fibres removed. Dampen the surface with clean cold water.

Firstly, apply Demidekk Terrassfix by brush whilst keeping the surface moist for 15-20 minutes, apply more Terrassfix if required. Then scrub lightly along the grain, taking care not to damage the surface. After 20 minutes, rinse the surface thoroughly with water which should remove the old stain without the need for high pressure jetting. If residues of old stain remain, remove by repeating the process. Care should be taken around flower beds and shrubbery as this product is based on sodium hydroxide.

Applying Demidekk TerrassfixOnce the decking is dry, apply Demidekk Terrasslasyr along the length of each board, following the grain. Avoid surplus glaze on the surface, this should be brushed out until it penetrates the wooden surface. The glaze will penetrate the decking and only form a light film on the surface. Wipe away any excess by using a lint cloth. Cut edges are more absorbent, so 2 coats can be applied in these areas for extra protection.

Demidekk Terrasslasyr is touch dry within 3 hours and walk on dry in 8 hours. Your patios, balconies and decking will retain its appearance for three years and will not require repainting, saving time and money.
