Repair roof of the house the roof with his hands

To protect the roof from imminent destruction,its paint.But the paint itself breaks down over time from the effects of weathering, dust and sand, sun.Significantly accelerates the destruction of the paint layer carbon dioxide, which is quite a lot in the air.Hydrogen sulfide discolors most paints.Dust and sand, periodically carried by the wind, abrade the paint mechanically.Smoke simply pollutes the painted surface.Also, during cleaning of the roof, for example, damaged paint snow cleaning tool (e.g., broom).Sun also actively discolor layer of finishing material, so the light fastness of the ink should be used whenever possible.

If the roof surface is painted smoothly, then it does not retain dust on themselves.Paint can lose elasticity because of its low quality or uneven application or inclusion of large fragments pigment mixed with linseed oil.Sometimes, when there is no ink dough, prepare it with your hands, mixing dry pigment with linseed oil.This can turn out very low-quality paint.On the surface, bubbles can appear, if the paint is applied to the dried after spackling bad or dirty surface.Cracking occurs when the paint is applied with a thick or uneven layer.If the paint is prepared on quality drying oil and apply a thin layer after drying it has a shiny surface.

When heated sun roof steel roof of the house expands.Since the thermal expansion coefficient of steel is greater than that of paint, broken layers of old paint that has lost elasticity.As a result, the surface is covered by a network of small cracks through which moisture penetrates, steel rusts, and it is necessary to paint the roof again.

Preparation for painting the roof

To paint the roof properly, it is necessary to do it in two, and preferably three times.Single staining gives good results and only leads to unnecessary costs.

Roof roof of the house must be thoroughly prepared for painting.Properly prepared surface will provide reliable adhesion of the material.Preparation is cleaning the surface from dust, dirt and rust.Heavily rusted place cleaned with a steel brush to the metal.After that swept away the dust and immediately applied the first coat of paint.Then it is checked for cracks in the roof or punched seats formed during steel cleaning snow scrapers.To detect the smallest of holes is better to inspect the roof on a clear sunny day.Inspection is better to produce together - one with a long stick inspect the roof from the bottom of the attic and features a stick holes, these holes the other notes in chalk.Thereafter defects can be eliminated.The hands it will be done better and more reliable than the involvement of third parties.

Start with the roof repairs should be glossing over the holes on the ridge, carefully zaglazhivaya putty knife.Putty is made from crushed chalk mixed with the drying oil.The resulting cement thus obtained a strong and resilient, well maintained on the surface during drying does not crack.A similar putty can close small openings in the plane.You can put on a layer of putty fabric patch and then paint.

holes in the roof of the glued patches of thick fabric or canvas.Cut to fit the hole patch impregnated with the wet paint of red lead on drying oil and, having wrung out of excess paint is applied to the hole, well smoothing stiff brush.After drying of the patches, you are ready to complete the color of the roof.

Paint roof in 2-3 layers with their hands

For the first layer of paint should be more liquid than the subsequent layers.Liquid paint penetrates into all pores and adheres well to the surface.The first layer of paint has to dry for about five to seven days depending on the season and the weather, and then applied a second layer.

For the second and subsequent layer taken about 0.5 kilograms of linseed oil per kilogram of dough-like paint.Flow pigments depend on their type and the desired color saturation.For example, one square meter of roof consumed from 180 to 200 g of ocher, or from 250 to 280 grams copperhead.The longest is the paint on the copperhead.

the third time paint is applied in 5-10 days.On average, oil paint dries completely within 10 days.Such color-drying mode ensures high quality work.Practiced second coloration after two days of drying of the first layer, but this practice does not give a proper quality.Staining of the roof is carried on the same technology that the color of the walls or ceilings.Worn brushes for painting a new roof is less than the color of the old coating.

During staining of the roof, the paint is shaded along the slope.First painted roof slope, further work is continuing on the ridge to descend.In the brush is typed a bit of paint, which is shaded with a thin layer.

work on the roof of recommended shoes with felt soles or boots.You can bind to a conventional shoe felt sole.Felt does not slide on the steel and does not destroy the fresh coat of paint.

If the roof is not protecting grids, should be insured with a rope tied to the rafters, purlins or beam.It is inadmissible to tie a rope for a furnace or other pipes!

inner side of the roof Coloring

Steel roofing rust, not only outside but also inside.The most likely place rust - between the crate.Part of the roof lying on the crate, can not rust, as protected by the boards.Rust occurs because of the penetration of warm air into the attic through the soffit.Practice shows that most often are rusted space between the crate, but they can also be a crate.To protect the roof from rust must be cleaned between steel crate with a steel brush and paint over twice.Two-time painting will extend the service life of metal roofing.If there is rust on the galvanized steel roof should immediately remove rust, spot primed with purified liquid paint and cover with two layers of paint.
