Moment liquid nails: purpose, application and proper use

This type of glue, such as liquid nails, is now very actively used in construction and repair. When performing installation, there are simply no analogues for it. In some situations, liquid nails can speed up and significantly simplify the work process. Liquid nails “Moment Installation” allow you to avoid using a hammer drill, hammers, self-tapping screws, screws and other parts in your work. It is worth considering in more detail the existing varieties of liquid nails and the main areas of their application.

Purpose

Construction adhesive “Moment Installation” is used for the following purposes:

• for installing mirror bases on different planes;
• for attaching PVC panels;
• to attach shelves and decorative structures to any base;
• for fastening tiles.

Waterproof, which allows it to be used in conditions of excessive dampness. They can be used to glue tiles or mirrors in bathrooms, showers, swimming pools, kitchens, etc.

Why are they needed?

The range of bonded surfaces is quite wide: for plastic, ceramic tiles, gypsum panels, metal, chipboard, fiberboard, OSB, foam and gas block, bricks, polyethylene, glass, Teflon, concrete and others. Allows you to connect even loosely adjacent surfaces. Some types of LG (liquid nails) can withstand loads of up to 90 kg / cm²!

Considering the relatively high cost of LG, it is irrational to replace them with simpler and less expensive adhesive compositions, but for minor repairs (tiles have fallen off, wallpaper or baseboards have come off, etc.) - it’s always just right.

Types and composition

1. Based on synthetic polymers. Additional components are solvents of organic origin, which explains the pungent aroma. Liquid nails react with plastic and PVC, so it is not recommended to connect surfaces made of these materials. The marking on the products of this group is “MR”, it is placed on the packaging. Synthetic compounds are highly durable and resistant to moisture. Due to easy flammability, use of the product near open flame is prohibited.
2. Acrylic based. The marking indicated on the container is “MB”. They are neutral in composition, so they are suitable for work inside the house. Usually they install baseboards, fillets or PVC tiles.

Manufacturers of products display all information about the composition, main qualities and types of materials that can be glued together on the packaging and official website.

What it is

When purchasing liquid nails, not everyone reads the instructions for use. The material is so widespread and accessible that it seems that there are no surprises to be expected from it. But this is not so, since the general name hides several solutions with different characteristics. In the original version, the glue consisted of artificial rubber with the addition of polymers.

When it first appeared, especially plastic clay, which was mined in Texas, was used as a fine filler. Since such raw materials could only be used in America, and the adhesive composition turned out to be successful, experiments began with other additives. Thanks to this, many varieties of the product appeared, but the name remained.

Glue Moment “Liquid Nails” is produced in 16 variations. Each has its own adhesive strength, differs in composition and is designed for a specific material.

• Express MV 50. Universal assembly adhesive, does not contain solvents, used for joining wood, PVC, insulating boards. You can plant baguettes, door jambs, and decorative elements.

• “One for everything. Super strong." Manufactured using Flexec technology. Plastic, monocomponent, has a high adhesive force, so it can be used to glue heavy and large elements. They can work on any surface with any porosity, seal cracks, and seal. Moisture accelerates the hardening of the joint, so it can be used in rooms with high dampness. They can be used to connect natural stone, concrete, brick. The product is not used for working with glass, copper, brass and PVC.

• “One for everything. Transparent". It has the advantages of the previous brand, it helps to seal seams in water, but not in conditions of constant immersion. Shelf life: no more than 15 months.

• Glue Express Decor. White acrylic composition. Quickly glues any materials, but maximum adhesive ability is achieved with hygroscopic surfaces. Suitable for fixing decor.

• “Moment Montage. Waterproof." It belongs to moisture-resistant products of class D. This is a universal composition marked MB-40. They can firmly glue any materials.

• "Super strong MVP 70. Transparent." Due to the gripping force of 70 kg/m. sq. quickly glues any materials. Typically, wall panels and interior design elements are mounted on it. There is also a white composition.

• "Superstrong Lux MV-100." It has the qualities of the previous brand, but its adhesion force is 100 kg/m. sq. To glue heavy elements to them, there is no need to use supports or clamps.

• “Extra-strong MP-55.” It is made on the basis of rubber. They can be used to glue heavy objects of any texture. After application, it forms a thin film that is dry to the touch, protecting the bonded surface from contamination. The strongest adhesion occurs at the first contact of the surfaces during the destruction of the protective shell, so it is not recommended to move the working elements after bonding.

• "Universal MP-40." Based on synthetic rubber. It is easy to wash off. You can glue fiberboard, concrete, marble masonry, natural stone, polystyrene panels, glass and fiberglass. Reliable and quick to engage. Can be stored at low temperatures down to -20 °C.

• "Installation moment for MP-35 panels." You can glue polystyrene and foam panels. The characteristics are similar to the “Universal MP-40” brand, it is just as durable, but can be easily washed off until completely cured.

• "Instant Grip MP-90." Designed for quick gluing of materials that do not absorb moisture. You can fasten polystyrene, foam, brick, plywood and stone bases.

• "Transparent combat MF-80." The base is Flextec polymer. The glue is characterized by fast setting and can be used as a sealant. Colorless, solvent-free. Smooth, non-absorbent materials can be joined.

• “Moment Fix. Universal", "Expert". Fixes almost instantly, has a coupling force of 40 kg/m. sq. Used for indoor work only. Between uses, the composition must be kept closed to prevent a film from forming. You can install ceiling slabs, floor moldings, wood and metal decor, sockets, wooden wall panels and fill small gaps up to 10 mm deep.

• “Moment Montage. Polymeric". It has an acrylic-water dispersed composition and has excellent adhesive properties. Can be used to fill deep cracks and becomes colorless after drying.

How to use glue

During work, you must follow safety rules.

The principles of working with “Moment Montage” will be as follows.

• Before starting gluing work, you need to clean the surfaces from dirt and foreign objects, sand them, then degrease them. The materials to be bonded must be at room temperature. The optimal air temperature for work is +10 °C and above. Some types of polymer adhesives can be used at subzero temperatures.
• If the glue is in the form of a cartridge, then before use you need to cut off the protective seal and put on the cap. The end of the cap is cut at an angle of 45° to the desired diameter. Next, the cartridge is installed in the construction gun: press the locking tab, pull the rod towards you, insert the cartridge into the gun body, push the rod back until the disk stops at the bottom of the cylinder. Make several idle trigger presses until the glue starts to come out. To stop feeding, press the locking tab. This movement reduces the pressure of the compound inside the cartridge.
• The glue is applied to one of the planes to be glued. This can be done in several ways. If uneven areas are glued, then the composition is applied pointwise. The dots have a size of 20 by 20 mm, applied every 0.2-0.3 mm. When you need to glue tiles or other materials of a small area, the glue is applied in waves, which enhances the primary adhesion. When gluing skirting boards and other narrow, long decorative elements, liquid nails are applied in a continuous strip. When the surface area is too large, a roller may be needed; it can be used to apply glue to even, smooth materials. A trowel is used to create greater surface contact and instant holding power. Using a notched trowel with a notch depth of 6 mm, the glue is evenly distributed over the material, with a distance of 2.5 cm from the edges.
• After application, the object is pressed tightly and fixed for a quarter of an hour. In order not to hold the element with your hands, you can secure it with masking tape or special fasteners until the glue dries completely.
• To prevent the adhesive from going beyond the joint, it can be limited by placing a toothpick on top.
• If the excess still protrudes beyond the seam, then the acrylic composition is dissolved by ordinary water, so it can be removed with a damp cloth, and white spirit will help to dissolve synthetic-based liquid nails. Excess glue is removed from porous surfaces after drying by careful cutting.

When you need to glue materials with low moisture absorption ability:

• the glue cannot be applied in a continuous layer, since in order to dry it needs to be in contact with air or ensure the presence of moisture;
• sometimes you need to apply glue first, and then after 5-10 minutes. separate the elements so the solvent can evaporate. Only after this can the parts be pressed tightly and secured.

Construction adhesive can be used as a sealant for joints up to 20 mm wide. It is necessary to carefully fill all cavities and press down the side surfaces tightly.

The average consumption of the product is 0.2-0.4 kg/m. sq. Synthetic compounds are characterized by rapid flammability, so it is better not to use near fire and not to smoke while working.

It is better to carry out gluing in a respirator, since toxic fumes from synthetic nails can cause harm to health.

Unused composition should be stored in a closed condition. Empty containers of liquid nails are disposed of as household waste. Do not allow any glue residue to enter the drain.

Instructions for using liquid nails

First of all, you need to clean the surface that you are going to glue and degrease it. Then apply liquid nails to this surface. To do this, use a special gun. The glue can be applied in dots, in a snake pattern, or in the form of a grid.

Press the two surfaces that need to be glued together very firmly. Give them the most correct position and hold it for several minutes. Two or three minutes will be enough. Then wait about 24 hours for the glue to dry completely. At the end of this time, you can begin to carry out mechanical impact on the surface.

Tips for beginners

• It is better to use a construction gun to apply the product. It can later be used to work with sealant.
• If work is carried out on newly constructed concrete walls, then it is better to postpone this for at least a month to allow the surface to dry and the concrete to set. If you intend to glue PVC panels to painted walls, they must first be sanded. If the surface does not absorb moisture well, then it is better not to use acrylic nails or to prime the surface first.
• To increase the adhesive properties of polystyrene foam, it is first coated with wood glue, which is diluted 1 to 1 with water. After drying, you can begin to apply the glue.

Complete curing of the composition requires from 12 to 24 hours; during this time it is not recommended to load the glued surfaces, so as not to reduce the quality of the gluing.
