Plywood is a building material, the active use of which requires the production of furniture, packaging and even the automotive industry. The wood veneer of coniferous trees is used for the manufacture of this multilayer material. The result is a solid construction that can be attached with screws, nails and bolts, but glue is the most convenient option.
Plywood laying methods
How to glue plywood to plywood? The most environmentally friendly is water-based glue. It is completely odorless, it can be diluted with water and used instead of a primer. Such styling requires additional fastening, and the main disadvantage is long drying.
Glue, based on a solvent, dries a little less - 3-5 days. In this case, it is necessary to pre-impregnate the concrete screed with a special primer. The downside is the pungent odor.
How to glue plywood to plywood and save time?This desire can be maximally satisfied by using a two-component adhesive. It dries in about 24 hours and does not need dowel-nails.
How to choose glue for plywood
The decision of the question of what is the best glue to glue plywood to plywood depends on the type of connection and further operating conditions. The process can be represented by self-installation of plywood on a screed or carry an additional function, for example, to strengthen the structure.
If you plan to use uncoated plywood, then you can purchase any glue. The main requirement is a dry and clean surface. To apply the composition on both surfaces to be glued, it is better to use a roller or brush. After that, you can strengthen the plywood connection with nails, screws or clamps. In conclusion, you need to remove the excess mixture.
How to glue plywood to plywood if solid sheets are to be used? You just need to cover the surfaces with the mixture, and then press them with temporary dowel-nails.
It is not recommended to glue the laminated surface covered with a film, therefore, before applying the epoxy, the sheets must be cleaned with sandpaper.
How to glue plywood to plywood so as not to disturb the texture of the material and not cause discoloration, but at the same time get a high-strength structure? PVA glue is ideal for interior work, and phenol or epoxy glue is ideal for exterior work.
The level of reliability of the connection is affected not only by the applied mixture, but also by a clearcompliance with the recommendations, since if the latter are violated, the properties of the glue may not fully open up.
Glue composition
At the heart of almost any adhesive for gluing plywood are the following components:
- main adhesive ingredient;
- solvent;
- filler, which is usually wood dust or flour;
- additives, on which the curing speed and maximum adhesion directly depend;
- plasticizer;
- antiseptic.
The hardener is usually some kind of acid or ammonium chloride, and resistance to getting wet is guaranteed by the presence of tannins (formalin, copper s alts, etc.).
Adhesive requirements
Adhesive for plywood should have the following positive qualities:
- reliable fastening of materials;
- ease of use at home;
- good moisture resistance;
- not susceptible to the damaging effects of bacteria and fungi.
It is equally important that the adhesive does not destroy the wood veneer and does not change its color.
Which glue is better: "KS" or "Tarbikol"?
When deciding how to glue plywood to plywood, people most often opt for "KS" or "Tabrikol".
A little more about their properties and features:
- Glue "KS" - a universal composition, which is characterized by a viscous consistency. The composition includes sodium liquid glass, as well as severalmineral fillers and additives. It is very convenient to use, in addition, it is not afraid of humidity, heat and cold. The question is tormenting, how to glue plywood to plywood on the floor? Glue "KS" will easily solve all the difficulties associated with the parquet board, fiberboard and chipboard products, ceramic tiles and glass.
- "Tarbicol" is a one-component polyurethane mixture, with which you can lay any parquet. Its main positive qualities include: good sound insulation, lack of water and solvents, resistance to ultraviolet rays and high humidity. In addition, "Tarbikol" is a two-component and is designed to work with a non-absorbent lacquered parquet base. It dries very quickly, so it is indispensable in conditions of limited repair time.
Influence of plywood brand on the choice of adhesive
The brand of suitable adhesive for plywood directly depends on the level of strength required and how high the humidity is in the room in which the structure is planned to be used.
What kind of glue to glue plywood to plywood if the finished product will be in a well-ventilated area? PVA, protein or synthetic works well.
If you plan to make country furniture that will be both indoors and outdoors, then it is better to use one of the synthetic compositions.
AfterSince the choice has been made in favor of a moisture-resistant material for the interior, it is necessary to determine how to glue plywood to plywood. Reviews indicate that the connection is best carried out with compounds based on urea resin. The use of uncoated sheets makes it possible to glue plywood with any type of glue.
How much glue do you need to lay plywood on a concrete surface?
The amount of consumption depends on the number of irregularities, the presence or absence of porosity and the quality of the screed. It should be based on the recommended consumption of 1, 2-1, 5 kg/m2, but do not forget that the plywood must be laid on the base without voids. Only uniform pressing of the plywood to the substrate can ensure optimal distribution of the adhesive over the entire surface.
Tools and materials needed for the job
Before you start working with plywood, you should stock up on the following tools:
- foam roller;
- clips;
- with a hammer.
You also need to prepare the necessary materials:
- blanks;
- sanding paper;
- nails.
Plywood gluing sequence
Before you get started, you should figure out how to glue plywood to plywood. The instruction below reveals all the subtleties of this process in as much detail as possible:
- First, plywood sheets must be cleaned of dust and variouskind of pollution. Sanding paper will be needed to remove the laminated layer.
- Then the plywood should be thoroughly dried.
- It is recommended to use a roller to distribute the adhesive to obtain an even layer.
- Now you need to press the plywood parts together with clamps. It is recommended to remove protruding excess with a knife and rags.
- If there are large parts, then they will need to be connected with nails.
- Finally, when the adhesive mass is completely dry, the product must be released from the clamps.
Coffee table from plywood scraps
A lot has been said about how to glue plywood to plywood, but how to make something useful from this material?
After various repairs, there are a lot of scraps of plywood that just go to the trash can.
But these pieces are ideal, for example, to create an unusual and beautiful coffee table.
List of materials and tools needed for work:
- a whole piece of small thick cardboard for the template;
- many plywood pieces of the same thickness that will form the main structure;
- moisture resistant glue for wooden surfaces;
- jigsaw;
- pencil;
- vices;
- circular saw;
- grinder;
Plywood Bonding: Case Study
How to quickly make a plywood table? First you need to make a paper template for cutting the legs of the product. The coffee table will look good on openwork or curved legs.
You need to take a large sheet of paper and draw legs on it in 1:1 scale. When transferring a drawing to cardboard, remember that the finished design must be located on symmetrical legs.
After completing the work with the template, you can proceed to gluing the plywood pieces. The manufacture of the structure must be carried out so that the shape resembles the future legs of the table. The gluing of each 2 parts must be accompanied by the removal of excess mortar and tight compression of the plywood pieces. At the end of the work, the legs should be placed on a flat surface, put a template on top of them and circle its outline with a pencil. To trim the excess structure, you will need a jigsaw. Place a worktop on top of the product and connect the parts together.
