PLASTOR: a complete range for the maintenance and protection of exterior wood

Wood is proving itself to be a material of choice in many construction and development projects. Outdoors, its warmth and authenticity enhance restaurant terraces, pool decks, pontoons, and building cladding. As construction professionals, you know better than anyone: this nobility comes at a price. Wood is a living material, sensitive to the ravages of everyday life.

Subjected to climatic conditions, UV rays, pollution, and even biological attacks, it requires special attention to maintain its beauty and structural integrity. Poor protection leads to premature aging: graying, stains, cracks, and even deep degradation.

To meet these challenges, PLASTOR, a French specialist renowned for its wood solutions, offers a comprehensive and proven method. It's not just a matter of applying a product; it's also about following a rigorous protocol that guarantees the longevity of your structures. Let's take a step-by-step look at how to restore and sustainably protect exterior wood.

Step 1: stripping, the essential stripping

First and foremost, impeccable surface preparation is the secret to a successful finish. Stripping is often the first step. Its goal is simple: to remove old finishes such as paint, varnish, or flaking stain. This stripping of the wood is essential. It ensures a healthy surface that's perfectly prepared to accommodate the new protection. Indeed, good adhesion is synonymous with durability.

For this operation, PLASTOR developed its Gel Stripper.

  • Performance : its solvent-based formula effectively softens the most stubborn layers.
  • Convenience : its gel texture prevents drips, making it ideal for vertical surfaces such as cladding or shutters.
  • Fast action : it acts in just 15 minutes on acrylic finishes, saving you valuable time on your construction sites.

Step 2: Cleaning, for impeccable cleanliness

Over time, wooden surfaces accumulate various contaminants: dust, moss, food stains, etc. A thorough cleaning is therefore essential. It not only purifies the surface, but also removes any microorganisms that might thrive on its surface.

Le Concentrated Terrace Cleaner PLASTOR's product has been specifically formulated for this task. Particularly effective on exotic woods, autoclave-treated pines, or composite woods, it removes dirt and even mold without altering the wood's color. Its concentrated, dilutable formula is both economical and environmentally friendly, and safe for the surrounding flora and fauna.

Step 3: degreasing, the radiance boost

Exposure to UV rays and harsh weather is the main cause of wood graying. This natural phenomenon, caused by the degradation of surface lignin, can give your work a dull and neglected appearance. Fortunately, this isn't inevitable.

The stripper is used to restore the wood to its original color. sober PLASTOR, thanks to its concentrated formula, brightens wood and revives its natural color. It eliminates grayish veils as well as stains and mold.

  • Its non-drip gel form ensures easy application and prolonged surface action for maximum effectiveness.
  • Odorless and ready to use, it is used after cleaning to prepare the wood to receive its finish.

The expert's opinion, PLASTOR: "Good surface treatment cannot be improvised. Each step, from stripping to treatment, is a link in the sustainability chain. It is this rigor that guarantees the longevity of the work and, consequently, the satisfaction of the end customer."

Step 4: Treatment, preventive and curative shield

Some types of wood are more vulnerable to attacks by wood-boring insect larvae (capricorn beetles, woodworms) and fungi. Appropriate treatment is the best way to preserve the structural integrity of the wood over the long term.

Le Multi-purpose treatment PLASTOR offers a dual insecticide and fungicide action.

  • Preventive action : it protects healthy wood against future attacks.
  • Curative action : it eradicates parasites already installed in the wood.
  • Full compatibility : colorless and non-greasy, its formula is compatible with all types of finishes. It is applied to raw, dry and clean wood.
  • Comfort of application : classified A+, it guarantees low VOC emissions and is easily applied by spraying.

Step 5: Protection, choosing a durable finish

Once the wood is prepared and treated, it's time to apply the final protection. This will act as a shield against harsh weather and UV rays. PLASTOR offers two main product families for this crucial step: stains and saturators.

  • The stains : microporous, they allow the wood to breathe while protecting it. They are ideal for vertical surfaces. Their wear by chalking (a light dusting on the surface) greatly simplifies maintenance, which generally does not require sanding.
  • The saturators : non-film-forming, they do not create a surface film but penetrate the wood to nourish it deeply. They preserve the natural appearance and feel of the material and are suitable for all types of wood, on horizontal and vertical surfaces. Maintenance is done by simple reapplication, without flaking.
