In suburban areas, their owners today often erect frame-panel houses. The walls of such buildings are often sheathed with OSB plates. The material is easy to install, durable and environmentally friendly. However, OSB boards, unfortunately, do not differ in particular aesthetic appeal. Therefore, many owners of suburban frame houses are interested in whether OSB can be putty.
They leave the walls sheathed with this material, without additional decoration, mainly only in utility rooms. In all other cases, OSB boards are putty and subsequently stained or glued with wallpaper.
To finish such walls, of course, is necessary with the exact observance of certain technologies. You need to know how to putty the OSB boards and how to do it correctly. Otherwise, the decorative design of the walls does not last too long. In addition, with the wrong approach to business, OSB boards can simply warp.
What is the material?
OSB boards are made in enterprises by pressing wood chips. As a binder in the production of such material, a mixture of resin, glue, paraffin, etc. is used. Chips are stacked in the production of OSB boards in stages. Accordingly, the finished material itself is layered.
Due to this structure, as well as due to the fact that their production uses natural wood, OSB boards, unfortunately, are afraid of moisture. That is why you need to know exactly how to putty OSB. Finishing material for such walls should be chosen with all responsibility. Not every composition is suitable for facing such plates.
The main stages of work
Puttying walls from OSB is usually done using the following technology:
plates are carefully ground with a large emery cloth;
cover the walls with a primer;
actually puttying the surface.
At the final stage, the walls are again sanded with fine sandpaper and painted or glued with wallpaper.
How to putty OSB board: the choice of materials
Of course, the tool that is supposed to be used for wall decoration from OSB should not primarily contain water. Otherwise, the plates may swell and lose their original shape.
So how and how to putty OSB under wallpaper or painting? Used for facing such plates are usually products made on the basis of drying oil or glyphthalic varnish. Compositions designed for wood finishing are best suited for such a material. It can be, for example, nitro putties or oil-glue means.
It is also possible to purchase a synthetic base for finishing OSB walls. Very often, such plates are also putty using a special tool specifically designed for OSB. Today, in some construction supermarkets, if you wish, you can buy such compositions.
The primer for pre-treatment of OSB walls in most cases uses an adhesive primer. The surface of such plates are very smooth. And when applying the soil of another variety, there is a likelihood that the putty applied to the walls of the OSB in the future will simply leave.
OSB plates themselves when building a house, of course, you also need to choose the right one. Industrial enterprises market four varieties of such material, marked with numbers from 1 to 4. The higher the plate number, the stronger it is. The material marked 3 and 4 is also characterized by increased moisture resistance. It is these plates that should be used for cladding houses outside and inside in wet rooms.
Is it possible to use the most popular and cheap putties
Concrete and brick walls of country houses and apartments in high-rise buildings in most cases are covered with cement or gypsum putties. Is it possible to putty the OSB plate with similar compositions?
Cement means for facing OSB surfaces is never used. Firstly, such putty is usually made using water. Secondly, for too long this type of finish on the OSB, unfortunately, does not hold in most cases.
Plaster compositions can be a good answer to the question of how to putty OSB. Sometimes such materials for decorating walls of this type are used. But in most cases, gypsum compositions improved by polymers are used for finishing OSB.
Sometimes owners of frame residential buildings are interested in how to putty OSB plates on the street. It is not worthwhile to use this method of exterior decoration for surfaces of this type at all. From the street side, it is better to plaster OSB walls with mineral or silicate composition or close them with hinged facades.
What tools will be needed
To putty the OSB boards, you will need to prepare:
small and large sandpaper;
sickle for reinforcing joints;
rubber spatula and roller;
a plastic bucket for mixing the solution;
drill with a construction mixer.
You will also need a reinforcing mesh and tape measure.
Recommendations for sanding walls
So, how to putty the OSB boards for wallpaper or painting, we found out. But before starting the decoration, in this case the walls, of course, must be carefully prepared. First of all, their surface should be sanded. The purpose of this operation is not only the alignment of the plates, but also the removal of the upper impregnation layer, due to which subsequently the primer will not be able to penetrate the thickness of the material.
OSB walls are usually polished with large sandpaper. At the same time, such an operation is allowed both manually and using a machine. Technologically, grinding OSB is a simple matter. However, this procedure usually takes a lot of time. In addition, such an operation also differs in labor costs. Therefore, experienced craftsmen recommend that beginners purchase already polished OSB for inside wall cladding of the frame house. Such plates are slightly more expensive than ordinary ones. The time and effort in using them can save a lot of weight.
How to prime walls
Gypsum, oil, etc. means - a good answer to the question of how to putty OSB. But high-quality without prior priming, such a finish will not work. The purpose of this preparation is also primarily to increase the adhesive properties of the OSB surface. Also, the use of a primer allows to avoid further impregnation of the applied putty layer with tannins and resin from the plates. Without primer, ugly stains may subsequently appear on the finished walls.
Plastering slabs with such compositions is allowed in one layer. The primer is applied to the surface of the wall and rubbed thoroughly using a roller. At the end of the preliminary decoration, a technological break is made until the wall dries. Depending on the type of primer used, this period can be 4-12 hours.
Putty application
Finishing the OSB walls with putty is allowed only at positive temperatures and with humidity not exceeding 60%. If this rule is not observed, the plaster layer subsequently quickly crack and fall off.
They putty the walls of OSB, usually in two layers. The material is applied to the plates and carefully leveled in the horizontal direction. At the same time, they use it with a spatula, and then with a rubber roller. Then a little more putty is applied to the wall and it is leveled this time in the vertical direction.
After all surfaces are finished, they arrange a second technological break. The drying time of the putty coat before staining or applying wallpaper depends on the type of composition used. But most often, the final decoration of the walls is started no earlier than in a day.
Before painting or wallpapering, putty walls are cleaned with fine sandpaper. For this purpose, of course, you can use the actual paper itself. But it’s better to purchase a special painting grater. This tool is inexpensive, and homeworker can save a lot of energy.
Useful Tips
According to the technology described above, OSB walls can be puttyed quite qualitatively. But for those home masters who are used to doing everything thoroughly, it is worthwhile, among other things:
apply soil to the ends of the OSB slabs before sheathing the walls from the inside;
glue the joints of plates with serpyanka before puttying;
reinforce the walls before applying putty with a paint net (using brackets as fasteners).
What you should know about
Before painting, the OSB walls should be puttyed, of course, in any case. When using wallpaper as a decorative finish, this procedure is not always mandatory.
OSB plates - the material itself is quite even. Therefore, before gluing with vinyl or non-woven thick wallpaper, they do not need to be puttied. The walls in this case are preliminarily grinded and coated with a primer. OSB should be putty only when using paper or any other thin wallpaper for final finishing.
Putty OSB: reviews of homeowners
So, we found out whether it is necessary to putty OSB of frame country houses. This procedure is in most cases necessary. Many owners of private residential buildings consider this technology for finishing OSB boards quite suitable. The top protective layer of this type on chip walls can last several decades. But of course, the durability of the putty finish in the first place will depend on how accurately all applicable technologies were followed when applying it. Owners of country houses, of course, do not recommend breaking the rules for filling the walls of OSB. Otherwise, it may turn out that the work will have to be redone within a couple - three years after finishing.
The advantages of filling OSB walls, the owners of country houses, among other things, include the aesthetically attractive appearance of the premises. The compositions on the surface in this case are applied in a thin layer. After all, OSB plates, among other things, are even. Accordingly, even without the use of beacons, such compositions on the walls can be applied very qualitatively in terms of surface smoothness.
