Liquid nails: what is it, how to apply?

Liquid nails have been used in construction and renovation since the 1970s. They are respected both among professionals and in everyday life, and all thanks to their reliable fastening.

The substance in question is a construction adhesive with a very strong attachment. It differs from the usual assembly glue with a non-standard composition. In addition to synthetic rubber and polymers, liquid nails contain fine abrasive grains that give the bond strength comparable to conventional nails.

Liquid nails provide high-quality and long-lasting adhesion of even those materials that do not lend themselves to conventional construction glue.

With their help, you can glue:

  • drywall;
  • ceramics;
  • wood;
  • glass;
  • concrete;
  • stone and so on.

With the help of this composition, the materials are connected tightly, while the seams are not affected by high temperature, moisture, and rust does not appear. The strength of the composition of liquid nails is ten times higher than that of PVA glue. The speed of drying allows you not to hold the glued surfaces for a long time with your hands.

The composition of liquid nails may differ in the main component. They can be:

  • synthetic rubber;
  • acrylate latex.

When using the first option, be sure to wear a respirator and gloves, as it can be dangerous if it comes into contact with the skin. The second option is harmless, it is recommended to use it in rooms protected from moisture.

For convenience and uniform application, a special device was invented - a gun for liquid nails.

Types of tools

Depending on the purpose of use, guns are divided into household and professional (for example, for 2-component glue).

Professional liquid nail guns

Professional pistols are of the electric type, cordless and pneumatic.

The first involves squeezing out liquid nails by pressing a lever. The pressure drives a piston and a small motor, which, as the name suggests, is powered by electricity. The disadvantage of such guns is only in the limiting length of the wire.

Pistols of the second type work on the same principle, with the only difference that they are powered by the energy of a battery or battery. Such tools are quite light (1.3-2.5 kg), the seams lie flat, without smudges. One battery lasts about 90 minutes of continuous use, enough to cover a large area, then you just need to change the battery.

The next type of pistol is pneumatic. When the lever is pressed, air is supplied from the compressor under pressure, due to this, the mechanism is activated.

It is convenient and quiet to work with such a tool, moreover, you do not need to spend money on electricity or batteries.

Household Liquid Nail Guns

For small household jobs, usually mechanical pistols are used, which are of three types:

  • half-body;
  • skeletal;
  • tubular.

The half-body pistol has a half-open view, in which you can see how the rod pushes out the glue. A small 310 ml tube is inserted into such an instrument.This is a budget type of pistols due to the fact that the tube is not fixed too firmly in them, it can shift, and then the seams will turn out to be uneven.

The skeletal sealant gun is the most popular. It is a structure of metal ribs, a stem and a handle, 310 ml tubes are inserted into it. Such a pistol holds the tube more reliably than a half-body pistol.

Tubular pistols are similar in appearance to a syringe. They look like a fully enclosed tube-and-stem frame. They are designed for frequent use, they are made of metal.

In such a tool, you can insert a large package of liquid nails with a volume of up to 1600 ml, which allows you to work for a long time without interruption.

Pistol design

The main components of the pistol, regardless of whether he is professional or household:

  • body for inserting a tube;
  • lever;
  • rod with disc at the end;
  • trigger trigger;
  • blocking tongue.

Instructions for use

Before using liquid nails it is recommended to prepare the following tools:

  • directly a tube with glue;
  • gloves;
  • knife;
  • a rag to remove excess;
  • dissolving agent.

Degrease the surfaces to be bonded and dry beforehand. The process of using the pistol is simple: cut the tip of the tube at an angle (start with the smallest diameter), pull out the stem and insert the tube into the body. Next, we begin the direct application of the composition: we press the trigger, the rod acts on the piston, and it squeezes the glue onto the surface. Pressing the lever frequently, squeeze out the adhesive in a line or dotted line, this will reduce the consumption of the substance. For gluing large areas, it is better to apply the assembly adhesive with a mesh. Do not load bonded surfaces until fully bonded. Most likely, you will read the exact drying time on the tube, on average it is 12-24 hours.

When finished, remove the used cartridge from the gun. To do this, clamp the locking tab and pull the stem towards you as far as it will go. Now you can pull out the cartridge. Next, wash the instrument with soap and dry it.

If glue gets on furniture, hands or other objects, it must be removed immediately, while the composition is not frozen. To do this, use acetone. If the glue is already dry, you can only get rid of it with a special cleaner.

Pros and cons of working with a liquid nail gun

For those in construction, the sealant gun has more advantages than disadvantages. It is not for nothing that it is widely used for various types of work.

The liquid nail gun allows you to:

  • evenly distribute the glue over the surface;
  • apply glue even to narrow and inconvenient places;
  • protect the skin from the ingress of adhesive;
  • dosed to consume liquid nails;
  • avoid contamination of the surrounding space and objects.

The disadvantages of the tool can be considered:

  • rather high cost;
  • battery or battery costs (when using a cordless gun);
  • electricity costs (when using an electric gun);
  • the need to develop the skill of using the tool.

It is definitely worth purchasing a gun for liquid nails if you do not want to remove random drops of glue everywhere, wash your hands in anger, apologize to your wife for the damaged parquet floor.

It is much more difficult to use assembly glue without a special gun, and without skill, the result may even upset you. The fact is that it is difficult to control the application of glue, it is uneconomical, lays down crookedly, and, most likely, you will have to wipe off the excess.

At the same time, the fastening remains strong due to the adhesive composition.
