The primer must be made for a maximum of 2 days after all operations for the preparation of wood. If we strictly observe this rule, then our surface does not threaten any “gifts” by nature, and it will also not suffer from high or, on the contrary, low temperatures and can easily withstand pouring rains.
Now we will analyze such a material as plywood and basic rules
For external use, you need to use the birch plywood, in which the FSF brand. Its distinctive feature is that it is moisture -resistant, namely this is what we need.
We can use this material for: the construction of buildings that are designed for household needs; for construction, various warehouses;
We can use this material as formwork;
We also have the opportunity to use this material when constructing a roof.
If we use these sheets exclusively for the outer surface, then we need to take care of additional protection, from moisture. Despite the fact that such plywood is moisture resistant, it still needs to be covered with special impregnations, or varnishes that prevent moisture from entering the plywood sheet. We need to primed irregularities on the sheet. If we do everything we need, we will protect not only the plywood itself, but also the wall that is under it. We can also close all the joints, using rectangular bars of thin dimensions.
After these operations, our walls in the house will become perfectly protected, and also get a beautiful view. And if we select a non -standard color scheme, then our house will look like on an advertising booklet!
