How to nail

There are so much heads of nails: smooth, with furrows. There are tens of types of nails. Where will it hold the construction? And where will it be eaten by rust? The fastening on nails is frequently considered to be unserviceable and weak bonding technique . But it is easy to make this connection rugged and enduring. For this it is necessary to use not any, fallen under the hand, nails, but in accordance with their destination. Since there is much of types of nails and methods of their use. Let us describe about this.

According to the classification of building materials nails - these are fastening, or hardware (fine details). There is a quantity of nails, which, depending on design features and utilized materials, can be used for the solution of different problems: from the fastening of usual board to the “shooting” of elements of structures to the ferroconcrete bases. The covering of made of planks floors, the fixation of plinths, the installation of window and door casings, the production of wooden stairs - here it is far from complete enumeration of the fields of nails application.

The elements of fastening in the process of operation undergo a number of loads. The latter can be distinguished by the value (weight, which maintains fastening),by the direction (longitudinal, transverse, angular), and also be static or dynamic. The correct selection of articles ensures the reliable and lasting operation of all connections in the living quarters.

Here are the councils of experienced masters which will prove useful to the successful work to builders:

• if you do not want the hammer to leave dents on the surface of component, wall, board and etc., use a core drill - metallic extension;
• the connection it is possible to consider as reliable only if the rod of nail on of two thirds its lengths enters into the body of lower from the fastened components;
• in order not to split board by thick nail, its sharp tip should be made a little chamfered. For this place the nail on its head and hit slightly the point by hammer; and the nails, cowed on the mitre, make the joint of components more durable. It is more expediently to incline a nail along the line of the direction of fibers of wood;
• in the naked surface the head of nail must be sunk by core drill and glazed
• nail under the load is driven in into the wall on the mitre, top down;
• if component is subject to dismantling, it is better to use a special (screw) nail with the slots on the head.

If you need to extract the disobedient nail, under tongs of naildrawer, which are concerned the surface of board, you should lay the plate, in order to decrease the exerted pressure and to warn the spoiling of wooden components.

Liquid nails

Liquid nails this is a construction glue on the basis of natural rubber and polymers for fastening of different building materials both uniform, and different (foam plastic and concrete, for example). Glues “liquid nails” most frequently go on sale in the cartridges with a capacity of 310 ml.One drop of this glue is capable of holding on the ceiling the 50-kilogram plate. Liquid nails are ten times stronger than PVA glue. The strength of such glue connections is sufficiently great - from 15 to 80 kg/sm2. The basic plus of liquid nails – they, in contrast to the hard, do not spoil a coating, they do not rust. All of you know, how it is unpleasant in the recently repaired apartment to twist in the screw for the hours into the concrete wall. Here liquid nails will help you. And not only here. The liquid nails have the wide specialization: they can be used in the sticking on any surfaces, including rough and porous.

Wall, ceiling and heat-insulation panels, particle board, fibreboard, wood, gypsum cardboard, brick, ceramics, stucco moldings, components from the polystyrene, the glass and the metal - here is not entire list of material identification, which can be stuck using the liquid nails. But before the purchase it is necessary to study the label.

Under the determination “liquid nails” hides itself the entire range of adhesives with the wide variety of the technical properties: some are intended in essence for the plastics and can be used in the dry quarters, others do not fear humidity and firm to fungi, the third do not contain harmful components, it is possible to glue entire contract by the fourth, the fifth possess the increased strength and seize fast.

“Neutral”, or “water-dispersed”, nails (that one and the same) are prepared on the aqueous solvent. It is not detrimental to breathe by them: water still didn’t poison anyone.It is not recommended to grease metals with the aqueous glue , furthermore, it cannot be used at minus temperatures. But nails on the organic solvents can be used also with minus of twenty, and they are gripped stronger. True, it is not possible to name frost-resistant glue ecologically clean (3-5 days organic nails sharply smell).

In conclusion it is necessary to say that the time of gripping of the different “liquid nails” modifications varies from 15 to 30 minutes, and complete polymerization happens after 12-24 hours.

Buying liquid nails, this factor compulsorily must be considered, otherwise it is necessary for you to press to the ceiling a 50-kilogram plate during a long time.
