How and what seams to seal the bulkhead

The bulkhead seal the seam

Currently for sealing inter-panel joints are mainly used such materials:

1. Polyurethane foam;
2. Sealant;
3. polyurethane foam insulation

These materials can be used separately and can be combined.

How to choose the most suitable material and work on sealing consider in more detail below.

seams are sealed with foam

can use assembly foam for sealing inter-panel joints.Its use has advantages and disadvantages.

advantages of using foam:

1. Qualitatively fills all the cracks and voids;
2. Easy process performance;
3. small period of complete drying and hardening;
4. Acts as a thermal insulator;

Disadvantages:

1. high cost of the material;
2. destroyed by direct sunlight.

Based on the above facts, we can conclude that the foam is perfect for filling small cracks from the apartment.

Instructions grouting assembly foam.The selection and purchase of materials

First we need to choose the high-quality materials and buy them.By appointment emit 4 options foam.Get detailed advice can be in the place of sale.Also, when selecting such foam should consider its characteristics: expansion coefficient, density, shrinkage, adhesion.

Preparation

surface secures access to the seams and clear them from the old sealant.We took out the old materials used to seal the joints, and then thoroughly cleanse the surface with a brush or brush and wipe with a damp sponge.

foam application

After all the preparatory work has been completed, you can proceed to the direct application of foam.

final stage

After the foam completely hardens, it can be trimmed projecting parts and proceed to putty.

It should also be said that if the crack is very big, then one component foam can not do.It should be further laid in the slot heating material.

All works using foam can only be carried out in cold or dry weather.In no event it is impossible to carry out work in high humidity.Since this will lead to the opposite effect, since the water in freezing temperatures will expand, thereby destroying the joint.

seams are sealed bulkhead of the apartment with the help of polyurethane foam insulation

Represents the material polyurethane foam tube with a hollow or solid structure.For sealing gaps hollow better use since it is easier to pick the desired diameter and is more flexible.

Advantages:

1. Low cost;
2. Easy installation;
3. durability;
4. not rot;
5. resistant to the effects of the sun.

Disadvantages: If a bad seal absorbs moisture, then freezes and collapses.Not all areas of the seam tightly fill it so the water penetrates.

Installation

As with grouting, foam, to start preparatory work and purchase materials.Note that the diameter of the tube should exceed the diameter gap at 10-30%.

After completion of the preparatory work can start laying the pipes into the joint, tamping its special spatula.

then seam sealed with mastic.

Combined method of sealing cracks in

apartment Today, the combination of the above methods is an effective way of sealing.This combination is known as "Warm seam".

main stages of work on technology "Warm seam»

1. seam Cleansing.Remove all debris and clean the joint stiff wire brush, remove the dust with a vacuum cleaner and, if possible, wipe with a damp sponge.
2. Fill foam.Fill 1/3 of the seam to be, as it will increase in volume.
3. Before hardening foam polyurethane insulation laid, ramming it with a wooden ruler.
4. sealing mastic (sealant).You can use the cement plaster.
