What glue to glue the cork to the walls - types of compositions
Cork wallpaper, panels and other coverings made of such material began to be used quite recently, although the material itself has been used by mankind for many centuries.
If earlier they were used only for the manufacture of floats, shoes or covers, now they are more often used by designers for furnishing premises. Environmental friendliness, durability and beauty are the main advantages of the material, which increases its popularity from year to year.
For fastening to the wall surface, you need high-quality cork adhesive on the walls, as well as perfect knowledge of the technique of use.
At the moment, construction stores sell various types of cork coatings on floors and walls.
As for the wall materials, they can be of two types - panels and wallpaper. The latter can have a paper base or be a cork roll fabric. The first ones will play the role of decoration, and on top they will be covered with a wax or varnish composition. Due to their low weight, they can be glued not just to walls, but also to the ceiling. Due to their small thickness, the effect of sound and thermal insulation should not be expected from them.
Some wallpapers should be planted with glue, and with the rest it is enough to tear off the inner backing and attach them like a self-adhesive film.
Roll cork is also used as wallpaper, but it costs much more. It is strong, thick and comes in rolls that will not bend. Such material is 100% natural, and sometimes it is even sold without processing, and after gluing, additional decorative finishing is required. Most often, this canvas is used for pasting the hallway and kitchen.
Other materials for finishing cork:
The colored fragments in the two-layer type tiles show through a little.
A cork backing is used for the floor surface, which is usually laid under laminate and parquet floors. They help to reduce heat losses, reduce noise levels, and also help neutralize defects in the foundation. These substrates can be glued to the surface of the walls under any finishing material for warming the room, noise insulation, and improving the adhesion of the wallpaper to the surface.
Cork is quite expensive material , which can serve for many years, and therefore the adhesive composition for it should also be chosen according to the criteria of quality and work without complaints.
Most of the compositions work at temperatures from +16 to +21 degrees and humidity up to 70%.
By the way, the compositions should have a short time before initial setting, so that it is not required to press the cork panels for a long time. high-quality adhesive composition must have the following properties:
- Resistance to moisture.
- High adhesion to cork and backing material.
- Resistance to temperature changes.
- Absence of negative reactions to contact with paint and varnish, wax, varnish, and other finishing materials.
The main types of compounds that may be suitable for gluing cork materials are described below.
If you do not know what kind of glue to glue the cork on the walls, then it is worth choosing acrylic compounds. They are reliable, environmentally friendly, odorless, and also guarantee high quality adhesion of materials to each other, and professionals do not recommend using it for cork. After a while, the composition will destroy the surface of the cork coating, and also impair its strength properties.
Solutions based on water
The price of such adhesives is quite high, because most of them will be produced abroad. But the reliability will be at a high level, the consumption is low, because the adhesive composition will be applied to walls or cork material in thin layers. As the liquid evaporates and cures completely, the joint becomes much stronger. Water-based formulations are odorless, harmless, because they are made from natural ingredients.
Mixtures with solvents
Such formulations have a higher level of adhesion, firmly adhere wood, cork, and sometimes even universal and are suitable for most materials construction type.
They grab almost immediately, and there is no need to wait a long time for gluing the panel to the walls.
Please note that the disadvantages of such adhesives will be an unpleasant odor that comes from the organic solvents introduced into the composition. The adhesives will be toxic (before curing), and you will need to work with them with strict adherence to safety measures. Do not work close to sources of fire - all solvents are flammable.
Using a cork, you can finish the floor in rooms, while removing the old coating in the form of linoleum or laminate not necessary.
tiled "floating" cork floors are made quite quickly, and when moving, they can be easily folded and taken away.When properly adhered, the cover will soften the sound of walking and falling objects, and can also withstand heavy pieces of furniture.
Interestingly, cork can be used to trim the ceiling and walls, and at the same time, the same wallpaper that is bought for wall repairs will be useful for the latter. you can cover the surface in the room in a fragmentary or continuous method, as fantasy suggests. Moreover, cork can be used to trim pieces of furniture, for example, to replace damaged parts.
Before installation, cork sheets or even rolls should be kept indoors for at least 24 hours to help the material "adapt". Among other things, the roll cork is unwound and hung to stretch and take on a working shape. Slicing is easiest to do with a construction sharp knife, which has replaceable blades. Then they cut holes for sockets and switches.
Preparation of the base
Before gluing the cork wallpaper, the walls are thoroughly cleaned, dried and leveled.
It is also worth removing areas with mold that could damage the previous coating. Areas that crumble should be cleaned, then putty, otherwise the cork will lie unevenly. Cork materials do not fit well with gypsum, and therefore this type of plaster should not be used. Odorless cork wall adhesive is ideal for work.
Please note that the maximum height difference is determined by the floor, if it is large, you will need to first make a concrete screed.
At the end of the preparatory stage, the walls should be primed 1-2 times (there should also be no gypsum in the solution). For wood processing, primers with fire protection function are additionally used. The surface is dried to an acceptable level of humidity, and for this, a heat gun or air heater should be used.
Primer Application - What It Is For
Most people skip the priming step, although using a cork it will make future work a lot easier. The composition is partially absorbed into the upper layers of the base, strengthens the material and increases its strength.
After priming, adhesion to the adhesive will increase, and therefore the reliability of the adhesive joints will be significant. Moreover, when applying the primer, dust residues are removed, and the glue will lay down evenly, will not roll and stray into lumps. If the base is complex, highly absorbent, then it is better to apply the primer two times.
Immediately before the start of work, the walls are marked, especially if gluing is planned using a fragmentary method. Before attaching the tiles, you will need to draw a grid, and when pasting the walls with canvases, only signal lines can be applied.
If you do not do this, there is a risk of skewing the products, which is especially common when processing a large area. The easiest way to do the marking is with a laser level.
Sticking cork to walls
Usually start finishing the floor, walls from a window or from a corner. In general, this will not play a big role, the master will be able to independently choose a site to start repairs. After that, you should remove all sockets, switches, and cover the technological type holes with pieces of cardboard that are cut to fit the holes.
The peculiarity of cork fastening
Cork tiles are installed according to the principle of brickwork - the second row and all the others are shifted by 1/2 from each lower element. The wallpaper should be attached end-to-end, leaving no gaps or overlap.
The adhesive composition follows apply on cork only or on both surfaces - floor, walls and finishing material. The thickness of the layer should be observed according to the instructions, but it should not be more than 0.3 cm.
It is most convenient to apply the glue by means of a roller, notched trowel or comb (for very thick compositions). It is not necessary to immediately lubricate a large amount of material with an adhesive - the composition should not grab until it is applied to the right place. be sure to observe the time indicated by the manufacturer for correcting the cork position and fix it before the end of such a period.
After the element or strip is applied to the wall, it is carefully pressed, and starting from the bottom edge. In the case of wallpaper, the edges should be additionally greased with adhesive using a brush.
Then the cork is rolled with a rubber roller. Upon completion, you should wait for perfect drying, and then cover the seams and the material itself with a protective composition, varnish. It is impossible to neglect such an item, since otherwise the material will serve less. Formulations that contain wax are best suited.
If there is a solvent in the wall plug glue, then work can only be carried out in a respirator.
When the agent gets on the front of the cork, it will be extremely difficult to remove it, and it is better to protect the edges of the elements in advance with masking tape. The adhered drops are heated with a hairdryer, and then blotted with a napkin. It is better to replace heavily dirty areas with new ones. Cork is an expensive material, and you should work with it carefully so as not to overpay and immediately get an excellent result.
The best brand of adhesives
Among the means that can be used to connect cork products, imported manufacturers are more common.
You can not find them in all stores, and the range of such products is small.
This is a contact compound, which is special for joining different cork products, as well as for combined gluing cork and other materials. It perfectly holds the finish on metal and wood. The tool will be characterized by resistance to frost, economy in cost and consumption, strength of the glue seam after drying."Moment Cork" is resistant to alkalis and weak acids.
The most popular areas of use of the compounds:
Please note that you cannot use an adhesive composition for joining polyethylene, styrofoam, polypropylene, and also plasticized polyvinyl chloride. The product will not contain toxins, and even harmful solvents. If it hits different surfaces, wait until it dries, and also roll it into a ball and remove it.
