Construction steps of anticorrosive wood paint
A, the construction site, the pile of wood square must have a gap of 10- 12mm on each floor, and also prevent from being affected with damp or direct sunlight.
Second, in the construction, the existing size of anti-corrosion wood can be used. Such as cutting, drilling, etc. When necessary, preservative must be used for painting and repairing to ensure the integrity of the anticorrosive coating.
Three, the connection should be drilled in advance to reduce cracking.
Four, all connections must use hot-dip galvanized fasteners or stainless steel hardware to prevent corrosion.
Five, Jianyang platform and plank road, try to use long boards to reduce joints, in order to be beautiful. There should be a gap of 3-7 mm between the plates.
Six, the adhesive used in anticorrosive wood should be waterproof and weatherproof.
Seven, outdoor construction should do a good job of maintenance, such as brush wood oil, etc. , to avoid wood cracking and deformation due to sun and rain.
Eight, if you want to paint, you must choose water-based anti-ultraviolet paint, and don't paint the wet wood surface.
Nine, when the thickness is more than 35mm, in order to prevent its deformation, a small groove with a width of about 65438+/-00 mm can be opened on the center line of one side of the wood core. ..
Ten, different use environment (such as ground, underground or water) should use different grades of anticorrosive wood, to ensure the design service life.
How to brush anticorrosive wood?
1. Processing must be carried out at a temperature above 8℃.
2. Wood must be dry, and the highest moisture content shall not exceed 15%.
3. Before applying wood wax oil, the wood surface must be polished with fine emery cloth and wiped until the surface is smooth. If there are fibers on the wood surface, it can be lightly polished with P240 or above wood sandpaper.
4. Fully stir well before use, without dilution; If the viscosity of the product is high, a small amount of special diluent can also be added, and the addition amount shall not exceed 10%.
5. Brush evenly and thinly along the grain direction with a soft brown brush.
Remove the excess paraffin oil after brushing, and the amount of brushing must be small, not too thick; After the surface is dry, gently polish and wipe the coated object, and brush it for the second time in 12 hours. 6. Before wiping, soak the dust-free cloth evenly and squeeze out some redundant wax oil; When rubbing, the force should be even, neither too heavy nor too light. Firstly, alternately rubbing along the surface of the coated object for several times, and finally evenly rubbing along the grain direction during coating, so that paraffin oil can fully enter the grain, and standing to dry; After the surface is dry, gently polish and wipe the surface of the coated object, and then operate as above.
To sum up, the above is the construction steps of anticorrosive wood paint and how to paint anticorrosive wood. After understanding these decoration knowledge, do you have more confidence in the decoration?
