Paint for roofs of slate or metal
The contents
In recent decades a broad popular metal roofing. It is because of their high reliability and long service life, versatility and relatively low cost. The lack of colors is easily solved on your own through the use of paints for galvanized steel roofs.
The need of staining ↑
Despite the fact that the producers of galvanized sheets applying to use their products protective oil layer, about a year later he collapses under the influence of atmospheric precipitation. For this reason, it is recommended to treat the metal roof with a special paint. This will allow you to:
- to avoid rust and as a result of the demolition of the roof;
- improve appearance;
- despite the high cost of the paint to avoid an even more expensive replacement of the roof.
The choice of paint ↑
Paint roofs should be chosen taking into account not only the color Gama, but also in such characteristics as resistance to corrosion, temperature changes, the effect of the atmosphere and other negative factors. When creating roofs in recent years have increasingly used and black galvanized metal.
Accordingly, paint for metal roofs can be of several types:
- oil;
- acrylic;
- Coatings with the addition of anti-corrosion components.
The most economical option is staining the roof with oil paint. However, in the process of operation, this paint requires constant updating, incurring additional financial costs.
The best choice is to use a special acrylic primer-enamel. Such expensive paint is worth the high cost, long-term reliable protection of the roof, significantly extending its service life. Besides, unlike oil paints, acrylic primer-enamel roof provides a rather attractive appearance.
Preparing the roof for painting. ↑
As with any repair work, painting of the roof starts with preparation. From the surface removes dirt, old coating, if present, dirt and rust. For cleaning of the roof is best to use hard, and then soft brush, then rinse and dry the roof surface. Elements, rusted, treated with a special tool and immediately painted over.
Painting galvanized roof ↑
Before proceeding to the staining of the roof, most people wondered what kind of paint for metal roof is the most effective. In order to give the roof an excellent appearance and to protect it from damage galvanized coating use special protective equipment. Unlike conventional metal sheets «zinc» has a more passive surface and it is therefore necessary to select an elastic paint coating.
The best option is rubber paint that is designed for decorative and protective painting slate, tile, galvanized and other surfaces. This paint material is suitable for painting facades, walls and roofs. Has a high to different atmospheric conditions, elasticity, good adhesion, water vapor permeability, resistance to moisture and mechanical loads, and is easy to apply and dries quickly.
Staining black metal roof ↑
Used for roofing black metal must be subjected to staining. The application in most cases, alkyd and oil paint materials leads to the fact that the roof very soon have to repaint again.
In this case the most practical option is to use acrylic paints with special anti-corrosion additives. This paint, in spite of its high cost, will last much longer than cheaper counterparts. High elasticity and resistance to temperature extremes provide an opportunity to preserve the original appearance of the metal that has the feature to change its characteristics under the influence of the environment. While oil and alkyd paint materials do not have sufficient elasticity, resulting in roof over time, there is stratification of the coating and the formation of rust.
Also for painting of metal roofing can be used synthetic paint «4 seasons», which is an enamel of the highest quality, made on the basis of alkyd with the addition of titanium dioxide. This paint material dries quickly and forms a hard and durable coating. Enamel is recommended for interior and exterior use for painting metal, wood, concrete and plaster. The flow rate is 1 kg/15-18 m? for a single layer. The drying time of the layer – 6-8 hours.
Painted slate roof ↑
The benefits of using slate tiles when creating a roof overshadowed by such a disadvantage as unpresentable appearance, and the appearance of different vegetation in the process of long-term operation of the roofing material. To fix this disadvantage will need special paint for the roof, which shall enter a special frost – and water-resistant components.
As when painting any other roofing material, slate sheets must be cleaned of dirt and dust, cut vegetation, rinse and dry the surface. In case of detection of leaks or loose fixings it is recommended to perform the appropriate repair or completely replace, if needed, old leaves for new leaf slate.
Before application of slate roof, you must handle it with acrylic primer, which will remove the remaining dust will fill the smallest cavities and improve paint adhesion with the roof surface.
Before applying any paint for the roof, the coloring composition must be well mixed, until a homogeneous consistency. If the paint is too thick, you can add an organic solvent. This will allow you to apply paint material to slate the leaves evenly and fully soak the surface of the roof.
When painting a slate roof, as well as when working with metal roofing you can apply the paint by brush, roller or spray gun and is best in the two approaches. The secondary layer must be applied after complete drying of the first. Thanks to the protective layer slate roofing will be stronger morozovskoye and acquire a more aesthetic appearance.
