Wood is a living material and exterior woods which are subject to daily aggressions (climate, repeated use, etc.) require specific attention to guarantee their durability. Above all, do not think that once a cladding has been installed or a terrace installed, "the hardest part is done and that we will see later for the finish", as well as improvise or do without the cleaning stage before installation. application of a finish is very damaging. Magic in real life does not exist and without precaution, without maintenance, without protection, nothing holds.
Two essential recommendations:
- Always work on a clean surface.
- Always analyze the condition of the wood before any cleaning or protection decision.
Why is analysis so important before any action?
Woods do not all age in the same way depending on their species, their exposure, their finish, their use. They are subject to UV, bad weather, wear and tear from repeated passages... Some have protections, others do not. Depending on their nature, condition and appearance, the diagnosis is different. And making a bad decision, without doing an analysis beforehand, can lead to doing twice the work...
A short guide to analyzing and choosing options for cleaning wood:
- Gray and dull wood having simply aged in the weather: it is necessary to sober up
- Blackened, dirty wood: oil must be removed
- Wood covered with an old very film-forming finish, such as paint or stain: it must be stripped.
Owatrol solutions
Clean/Sober:
The wood has a dirty gray appearance, it has generally been left to weather without protection or with a non-film forming finish. It has only undergone the “water + UV + pollution” aging cycle: it needs to be sobered up to revive, clean and restore the wood to its original appearance.
How? 'Or' What ? NET-TROL® 200: It acts on all types of wood, its gel formula facilitates its application and its ultra-wetting power enables it to act in 15 minutes.
The plus: NET-TROL® 200 also eliminates runs and traces of tannin on certain woods (eg red cedar).
Deoiling:
The wood is blackened, clogged because it has received an oiled finish upstream, often poorly adapted (linseed oil, even motor oil...!). The oils applied cook under the action of UV rays and with the water become encrusted in the wood which blackens in depth. Sanding will not be enough and will not save money: You have to clean up and act in depth to remove the old clogged oils.
How? 'Or' What ? the NET-TROL® 400 oil remover makes the oils or dirt encrusted in the support soluble and leaves, after rinsing and neutralization, an impeccable wood.
The plus: Thanks to its excellent impregnating power, NET-TROL® 400 acts quickly and deeply.
Stripping:
The wood is stained or painted and must first be stripped of its multiple layers so that it can be worked on again. It is therefore necessary to strip and the action of DILUNETT® will make it possible to eliminate all the old layers of paint, stains or varnish as well as to remove stubborn stains.
How? 'Or' What ? The technical composition of DILUNETT® enables it to dissolve all fatty binder coatings and to eliminate up to 8 layers of paint. Thanks to its gel texture, it is easy to apply vertically and its formulation based on pine oil gives it optimal diffusion on the support while facilitating the perforation of the film to be stripped.
The plus: Solvent-free, VOC-free, non-volatile and non-drying, it remains active for a long time guaranteeing the total elimination of the various coatings.
NB: After the action of NET-TROL® 400 or DILUNETT®, it is imperative to stabilize the support with an application of NET-TROL® 200 after rinsing before applying the finish.
