Various wood products, wooden houses, wooden floors have always been and will be popular. In fact, wood is one of the first building materials in human history. For all its advantages, wood also has disadvantages. This is not too high strength, reaction to moisture and other disadvantages. Wood putty improves the properties of wood and hides surface defects.
Wood and putty
A variety of wooden products are processed with such materials. This includes old window frames, new hardwood and softwood joinery, parquet and much more. With this composition, you can get some benefits.
Thus, a layer of putty on wood allows you to prevent the absorption of moisture. As a result, the service life is significantly increased. So, due to the use of putty mixtures, it is possible to very successfully hide and mask all kinds of defects on the surface - various knots, cracks or chips. When the composition dries, a completely transparent layer forms on the surface - the natural structure of the wood is preserved. Putties for parquet penetrate very deeply intomaterial, filling all the irregularities, and also prevents pollution.
The main argument against coating wood products with fillers is that the material can swell when exposed to high humidity. It should be noted that any composition intended for finishing such a material will give the surface or product resistance to moisture. If the wood putty is chosen correctly, then all fears are groundless.
Criteria for selection of putties
When choosing a material, you need to proceed from several criteria. This is the maximum adhesion, that is, the ability of the putty to adhere to the wood in this case. Also, the composition must be elastic - elasticity greatly simplifies the application process, and then prevents cracking. A good and properly selected composition should dry quickly, be environmentally friendly.
If wood putty is chosen for finishing, then the fractions of the composition should be very small - this will make the thinnest and very smooth layer possible.
Types of compositions
There are several main types of puttying compounds. The differences between these materials lie in the main component on the basis of which this or that mixture is produced. Now we can distinguish gypsum putties, polymer compositions based on acrylic and latex, nitro putties, as well as adhesive and oil mixtures.
Gypsum putty for wood
These mixtures are especially popular in wood processing. The composition is characterized by excellent characteristics,elasticity, excellent level of adhesion, as well as good vapor permeability. But at the same time, gypsum is in no way suitable for use in rooms with high humidity and for outdoor work.
Acrylic putties
Acrylic putty on wood has a cost that is much higher than the price of gypsum materials. This slightly limits the possibilities of application. But the composition has a lot of advantages.
Acrylic compositions are characterized by good resistance to moisture, fire resistance, and wear. The coating dries within 6 hours after application. Acrylic-based materials are universal - they can process parquet floors, laminate, plywood, chipboard and other products. Acrylic-based fillers are considered the best when grouting parquet joints.
Similar mixtures are used for both interior and exterior finishing work. The main disadvantage, in addition to the high price, is the need to periodically update the coverage. It is also necessary to provide additional insulation in the cracks, as one putty composition may not be enough.
Latex materials
This product, like acrylic-based mixes, cannot be classified as accessible to everyone. Latex-based coating dries even faster than acrylic formulations. The coating will be perfectly even. Such products have high environmental safety. If you need to process the parquet board on the floor, then this is the ideal choice.
Nitro putty
In such mixtures there areorganic solvents, various petroleum-based resins and plasticizers. Coatings made using these putties are resistant to various aggressive chemicals and the surface is easy to sand. Advantage - despite the presence of solvents in the composition, there is no smell when working with putties on wood.
Oil putty for wood
Such products are made on the basis of oil obtained after the processing of natural drying oils. It also contains varnish and chalk. Due to the presence of drying oil, the mixture perfectly withstands moisture. Therefore, products puttied with oils can be used as facade elements.
Often, windows and other exterior parts are treated with oil fillers. This is a good choice for outdoor applications - the resulting coating will have high strength. Often, these products are used in conjunction with antibacterial treatments.
The only negative, in addition, quite noticeable is the long time required to dry the treated surface.
Glue based mixes
Such solutions are components that must be mixed immediately before application. The basis is PVA glue.
Producers
On the shelves of building supermarkets there is a huge number of compounds for varnishing or painting. Among the manufacturers are domestic and European brands. Among the most famous Europeanmanufacturers can be distinguished by the well-known Finnish brand - Tikkurila. Wood putties for indoor and outdoor use from this brand allow you to perfectly level even the most difficult surfaces. With the help of Tikkurila mixtures, the colors of different types of natural wood are copied. The coating obtained after treatment with these putties can be applied in all climatic conditions.
Also, the Lakra brand is popular with buyers. These products are perfectly combined with various parquets. VGT wood filler is well suited for painting.
Compositions of the Eurotex brand have a low cost, while the quality of putties is more than worthy. The products of the domestic manufacturer "Rainbow" are characterized by quick drying, as well as excellent adhesion. Wood putty "Extra" is suitable for sealing even very small and minor defects on wood products.
Preparatory stage
The preparation process involves cleaning the room from furniture. Large and heavy objects are protected with film or newspapers. Also, when working with putties, do not forget about safety equipment - it is better to stock up on goggles, a respirator, gloves.
Surface cleaning
If putty is used for painting, then it is applied to the most even and clean surfaces. The result depends on the cleanliness and how well the surface is prepared. It is important to completely remove the remnants of old paint, putty. To do this, you can use solvents and abrasives.materials. Also, nails and other metal parts are taken out of a wooden product. Then the surface should be treated with brushes and damp cloths.
Applying primer
It will not be possible to do without the priming process, since without this it will not be possible to achieve good adhesion. Most modern soils also have high antiseptic capabilities. The antiseptic will reliably protect the product from the adverse effects of bacteria and microorganisms. It is better to choose a primer on the basis of the same base as the putty composition.
How to putty?
So, to apply putty on wood for interior work, you will need a container where sucking powder will be poured, two spatulas - wide and narrow, an airbrush, and sandpaper.
Even before the bulk of the composition is distributed, the surface is carefully inspected so that there are no large chips and cracks on it. If these defects are present, then they are processed first. Large seams are covered with a special tape. This will make it possible to reduce the consumption of putty mixture and avoid cracking in the future. The tape is laid on a slightly dried base layer. Top with the finishing mixture.
Next, they gain mass with a narrow spatula and transfer the putty to a large tool. The composition is applied from top to bottom from the corner. The first layer should have a thickness within two to three millimeters. No matter how carefully putty is applied to wood (pine, etc.), after the coating dries, streaks will remain on it. Take them awayYou can use an old spatula or sandpaper. The final layer should be no more than 1.5 mm thick.
When diluting the finishing putty mixture, it is necessary to ensure that the solution is thinner than the starting solution. The mixture in liquid form is best applied with a spray gun.
After the finishing putty has completely dried, the layer is also treated with sandpaper. For acrylic, gypsum and oil compositions, conventional dry processing is suitable. If the nitro putty is being cleaned, then the abrasive must be moistened in water or solvent.
