How to protect outdoor wood

Como proteger la madera de exteriores - destacada

Outdoor furniture made of certain types of wood is widespread, such as teak, ipe, and other species that withstand inclement weather well.

However, wood, as the living material that it is, needs certain care to preserve both its properties and its natural beauty.

These cares, roughly, are included in two. Repair treatments, when there is already damage to the wood of some importance. And preventive treatments, which are applied precisely to prevent damage from occurring.

In this article we are going to focus precisely on the latter. We will see how to carry out the application of a preventive treatment, especially aimed at outdoor wooden furniture, with the aim of making it last for many years as new.

Preventive treatment to protect the wood

Last year we already dealt with the protection of wood, but focused on floors. In this article we talked about it “How to maintain exterior wood”.

As I already mentioned, the water, but especially the sun, and even worse, the combination of both, produce very negative effects on the wood, rapidly degrading it.

However, this can be avoided by applying the appropriate treatment.

Preventive treatment is not carried out with furniture paints as we know them. It is made with a special product that not only hydrates and renews the wood, but also restores its natural beauty.

The most appropriate thing is to apply the protector, with an open pore finish, which is especially indicated for the wood protection.

In addition to nourishing the wood, it contains a UV sunscreen that allows it to preserve its color like the first day, avoiding bleaching and deterioration of outdoor wood.

However, for in-depth protection, especially in the case of wood that is very exposed, it will be convenient to give a previous layer of protective background.

So in this article, and you can see it in the video that we include below, we are going to bring two garden furniture back to life.

While we go through the process step by step, we will tell you more useful information about these products.

Necessary materials

The first thing is to have all the necessary material at hand, such as:

Medium-fine grain sandpaper.

Fine steel wool.

Brushes.

Protective paper and/or plastic.

Gloves.

Mixer.

The protectors to apply.

And, of course, the furniture to be restored.

Preventive Treatment Procedure

To make this article, we have asked advice to segopi paintingsspecialists in all kinds of paints, varnishes and related products.

First step – Furniture cleaning

Well, the first thing we must do is remove any remaining dirt, as well as previous paint or product, grease, etc. that the furniture may have on its surface. This cleaning consists of a good sanding of the wood.

This task can be done with sandpaper, sandpaper, or even an electric sander. Whatever shape you use, the grit should be medium to fine.

But before sanding, we have to disassemble any accessory that is not made of wood and that can hinder both sanding and the application of the product. In our case we have used the Black+Decker Multievo multitool. If you want to see everything this versatile tool is capable of, here is a link to our article in which we carried out some extreme tests see article.

In our case, we have done it with sandpaper blocks since, although it requires more effort as it is a manual method, they are very easy to use.

Once completely sanded, we pass a cloth to remove the remains of the sanding.

.

Second step – Application of the protective background

We stir well (without shaking) the lasur protective background, and give a coat.

Application can be done with a drill, roller, or spray gun.

If you have noticed in the video, the background is more liquid than the finish. This is precisely so that it penetrates deeply into the wood.

Once the background coat has been given, we have to let it dry. Although this product dries to the touch in 30 minutes, for repainting it is necessary to allow between 2 and 3 hours.

Third step – Application of the open pore finish

Once the background is dry, and before giving the finishing coat, we will gently sand the surface. To do this, we will use fine steel wool.

Once all the furniture has been reviewed, we remove the dust and, now, we apply the finishing lasur.

This product, like the previous one, is formulated in an aqueous base. Which means that they are more environmentally friendly than other solvent-based products. And therefore, the utensils are easily cleaned with water.

This lasur is made up of flexible resins that penetrate through the pore, adapting and effectively combating the harmful effects of weathering and, most importantly, without modifying the natural appearance of the wood.

Well, once the lasur is applied, we let it dry between 2 and 3 hours, just like before. And we repeat the operation, since we have to apply two finishing coats. Do not forget the soft sanding between hand and hand.

After the second finishing coat, we let it dry… and, once 2 to 3 hours have elapsed, we replace the previously disassembled accessories, which, in our case, are the handles.
