Wood is subject to fire to a large extent than other building materials. To prevent ignition, it is necessary to observe constructive and chemical precautions.
Constructive measures are compliance with all precautions at the design stage of the building. Chemical measures are associated with wood processing. First of all, it is plastering, sealing with sheets of absinthe or tin, pasting with foil and polymer films. The most effective chemical measure is fire protection, which involves the processing of structures with special LKM.
Hidden structures (rafters, runs, etc. D.) protect against fire by coating. When the coating dries, the fire -resistant layer remains on the wood material. It is important to remember that the coating will not stay on the wood forever, so the regular update of the protective layer is necessarily. Apply coating with a brush in 2 entry. After the first entry, the composition should dry at least 12 hours.
Compounds used as coating:
• superphosphate (70% superphosphate and 30% water);
• sulfate -clay (47% – fatty clay, 3% – sodium fluoride, 25% – water, heated to 70 degrees, 25% – sulfate olcher);
• composition of table salt and dough from clay and lime.
Fire -retractable materials such as fire -resistant paints are also effective.
Types of such colors can be as follows:
• silicate;
• chloride;
• phosphate;
• silicon.
The advantage of fire -resistant colors also consists in their moisture resistance. Protecting the dwelling from fire, they simultaneously protect it from water.
Surface processing of wood with fire-resistant paints is carried out in several stages, a break between which should be at least 2-3 hours. The main tools are brush and spray guns.
Deep wood processing is associated with the penetration of the composition into the inner layers. Such a measure is carried out by dipping the material in the composition.
Protective and stabilizing effect gives wood processing by polymers, among which – phenolic, carbomic, silicon and furanic solutions.
As a rule, chemicals are harmful to health, therefore, starting to process structures, do not forget about your own precautions:
1. Check the presence of covers on antiseptic containers;
2. Carry out processing in special clothing.
3. Follow the direction of the wind to avoid harm from toxic fumes;
4. Take care of your face: use protective glasses; The mouth and nose should be covered with wet lamps from gauze.
5. Carefully read the instructions for use.
Do not have illusions about protective chemicals. In order for your house to be completely safe, it is necessary to combine chemical measures with constructive, paying fire safety enough attention at the very first stages of design and construction.
