Where is alkyd primer used?

Any surface should be primed before applying paint or varnish on it. This ensures durability of both the material itself and the paint layer. In order for the material and paint to withstand the effects of an aggressive environment, it is best to use an alkyd primer. This type of soil can be used for those surfaces that need to be protected from moisture.

When using an alkyd primer is best applied to the surface and alkyd paints.

Alkyd primer is one of the most versatile primer types. It can be used for woodwork, metal, concrete. When processing metal parts, external structures or structures, they will be almost not subject to corrosion. And with the subsequent use of alkyd paint, you can forget about corrosion for sure. When applying a primer, you will need a smaller amount of paint, because it will clog pores and small gaps, forming an additional protective layer.

It is possible to use this material also when processing wooden surfaces. This is a mandatory step before applying decorative materials. It will provide durability to a covering and ease when drawing a varnish or paint.

The procedure for working with concrete surfaces is similar: After applying the primer, apply white or any other paint.

This type of soil is perfectly combined with various alkyd impregnations, putty and paints, as well as with ordinary PVA glue. Do not use this type of primer to work with crumbling materials other than concrete.

Considering this type of primer, you must select a few main varieties differing in composition and properties.

• Glyphthalic Suitable for all types of finishing work, both external and internal. Used to create a protective film on wood, metal, glass and concrete. Be sure to apply paint or varnish over the ground to create a more powerful protective layer.There are separate types used only for metals and their alloys, they have additional additives to prevent corrosion.
• Perchlorvinyl primer is used only for exterior plastering or concrete work. Dries within 60-90 minutes.
• Polyvinyl acetate primer. Dries in 35-40 minutes, is used only in combination with paints.
• Composition with polystyrene. It is very toxic, so it can not be used for interior decorating. Used only for wooden substrates.

• Alkyd-urethane composition. Designed for metal processing only. It is often used when working with vehicles or metal structures experiencing various types of influence of the surrounding world: precipitation, temperature changes.
• Phosphating. Increases adhesion. Used only with metal.
• Inhibitory. Forms a layer of water and oil repellent surface.
• Passivating. Slows down the corrosion process. Forms a thin impermeable layer on the surface.
• Protector. Designed to work with rust. Forms a base that prevents the appearance of new scratches and rust spots.One of the most popular manufacturers of such a primer is the company "Prestige".

Due to the presence of various compounds, alkyd primer has a number of positive qualities:

• gives additional strength to the surface;
• possesses anticorrosive properties when applied to metal surfaces;
• additional protection against the spread of fungi, rot and mold;
• forms a protective layer against a wide range of temperatures;
• reduces the consumption of paint coating;
• increases the durability of the base itself;
• primer together with paint protects the material from various chemical compounds, high acidity and alkalis;
• wood when using soil is less exposed to moisture and hardly swells.

All alkyd primers are now sold in ready-to-use form, so the difficulties in working with them should not be. By following this step-by-step instructions, you can correctly apply a primer to any surface.

• The first step is to prepare the material for the application of the primer. If it is metal, then it should not be rust and corrosion.All burrs are removed from the tree, and the cracks are smeared and puttied.
• Next, you need to degrease the surface.
• The soil mixture is stirred. On the packaging, the manufacturer must specify exactly the consistency at which the primer will have the best adhesive index.
• Soil is applied with a roller or brush. For some species you can use a spray bottle.
• In the process of applying the material, it is necessary to ensure that the layer was as smooth as possible.
• Most often, after drying, you will need to apply a repeated layer.

Material consumption during spraying is minimal - about 130 grams per 1 square meter. m in two layers. When using a roller or brush consumption increases to 200 grams per 1 square. m. To carry out work on the application of primer is necessary at temperatures from -10 to +25 degrees with the use of personal protective equipment.

The use of an alkyd primer is a necessity when working with metal or wood surfaces. Improved surface performance - every builder should strive for this,and the use of appropriate formulations will help achieve this goal.
