How to choose a primer

primer - a liquid made up of mineral fillers and organic or inorganic binder ingredients.It is used for pre, starting treatment areas before finishing.Primer mixture depends on the durability of adhesion to the base layer putty surface: resistance to exfoliation and flaking, water repellency, mechanical strength, aesthetic appearance of the topsheet.The soil is a major contributing factor in the process of finishing, repair, preparation works.

How to choose a primer on the characteristics form the basis

base surface must firmly hold the cover.For this purpose, the primer used, the characteristics of which comply with the essential requirements: the deep penetration of the foundation and to improve adhesion to subsequent layers.

Uniform application of paint, putty, plaster, glue for wallpaper or tile it is possible to work after priming the surface.Selection of a suitable primer is made on the following criteria:

1. From the basics characteristics.It happens:

• little absorption,
• absorbing,
• high absorption.

used surface-penetrating primer.

2. From the front works:

• to prepare,
• alignment,
• increase or decrease vlagovpityvaniya,
• increase adhesion to the base layer.

applied universally surface soils.

Industrial soils are divided into groups according to their purpose:

1. primary training base foundation.
2. Increased adhesion between the base layer and finishing.
3. Surface dirt mixture.
4. Penetrating primer.

classification included in the binder ingredients or on the basis of:

1. Acrylic.The water-soluble primer of universal application.Designed to meet the new and old plaster, cement, concrete, brick, wood surfaces, DBP, DCP.

Which primer for wood surfaces to choose

For wood used several types of soil:

1. Standard.The basis is an organic solvent.A preferred formulation for the finishing of natural and synthetic wood coatings.A layer of dried soil does not furnish the other layers to soak into the wood.
2. water-based acrylic with.Plus this drug in the absence of a sharp odor.Dries quickly, does not form a plane to sag.
3. Aluminum.Specific primer designed for use on a particular tree species: teak, pine, deciduous with increased resinous, afrormozy.
4. For DBP fibreboard, MDF.Extruded products are very poorly absorb applied solutions.Do masters always there are difficulties in the selection of soil.Highly specialized water-based primer, designed for materials with low adhesion, penetrates well into the pores of the particle board, it does not slip on the surface, easy to apply.

What primer selected for laying of concrete or brick

concrete and masonry are cellular spatial system.For the surface treatment of these materials there are special grounds:

• Antischelochnaya.Construction materials contain a high concentration of alkali.This drug is resistant to aggressive alkaline conditions and substances that reduce the negative impact of caustic soda and does not allow him to destroy the coating finish.
• stabilizer surfaces.It is used as a binder for the crumbling, flaking materials, limits the absorption of the surface of old plaster and stabilize the volume lies before backing layer and strengthens its structure.Industry produces primer or as a clear white solution.Ideal for the treatment of limestone areas, intended for the application of emulsions or facade dyes.
• primer for concrete.Feature characteristics concrete surface - with low porosity clutch.On vertical concrete wall is very difficult to apply and keep from sliding layer finishing more than 0.5 cm. Processing and sealing of concrete surface according to the soil enhances the adhesion property allows to put a thick layer of new plaster, prevents subsequent shattering finish.Apply the usual way: brush, roller or spray.

• Vodoottalkivatel-primer.Cellular surface clutches has a large liquid-absorbing characteristics.To increase the water repellency of masonry use a primer.Quality coating process is facilitated by the addition of a fugitive dye preparation.It helps to apply the primer to the site without prolysin.Drying up, the dye becomes transparent or discolored.
• preparation to repel dirt.It is used to improve the aesthetic appearance of the front surfaces.It is applied on top of the drug paint on masonry.The transparent protective layer of the drug promotes smooth spreadable precipitation vertically, prevents dirty water stains, reduces adhesion and deposition of dirt.
• Alcohol quick-drying.The primer is designed to mask the problem spots on the painted surface.It has a white color, well masks stood out dark spots, prevents their protrusion on new finishing layers.Universal tool for use on creosote-treated wood, tar, bitumen.The solvent is applied to the primer denatured.Freshly applied layer is dry to the touch in 10 minutes.Complete drying takes place in half an hour.

How to choose a primer for metal

primer for metal is the main purpose - protection against corrosion.The composition of the primer for metal surfaces must include rust inhibitors.

Industrial drugs for the treatment of:

• Alkyd Iron minium.The most famous of soil-protective liquids.Used for all metal and steel surfaces.To create a reliable basis for the finish, enough to apply a coat of red lead.
• Ground water-based.Rapid drying fluid is used for surface treatment of most metals.Applied directly to the metal surface prepared fresh.Do not use on galvanized surfaces.

• Corrosion.It is used on the metal surfaces with a deep rust lesions.Before applying the old surface of the product was purified oxidized loose pieces.
• Universal zinc-phosphate.Used for ferrous and non-ferrous metal surfaces.It lies well and reacts with aluminum and galvanized.
• for galvanized metal.Galvanized surface is considered problematic because of low adhesion.Any damage finishing layer: putty, paint, lay down smoothly, slide, do not give an even layer.Primer with the addition of zinc phosphate and corrosion-resistant material forms on the treated galvanized surface passivation film increases the surface roughness of a subsequent application of paint or putty, provides protection against corrosion.
• primer radiator.It is used for extra protection, a coat of primer over the factory, before painting.Protects iron from corrosion, improves heat transfer and increases adhesion of paint.We select the same brand of paint by producers.

How to choose a primer or sealer

When using artificial materials often have to look for means to mask blemishes, to carry out processing of molds.For this purpose, industry produces porozapolniteli, coats unified, specialized staff:

• for PVC plastic, PVC.It used to update the window and door frames of PVC.It provides good adhesion of the upper layer finishes.It is used for treating joint plastic frame with concrete under the subsequent application of paint or decoration made from plaster.
• for ceramic tiles.Nanogruntovki.Used in ceramic tile manufacturing.Provides good adhesion of paint with gloss, increase protection against mechanical mikroudarov warn bundle finishing layers on the ceramic surface.

• for melamine.Used for small household repairs of kitchen furniture.It is used as a basis for a glossy or semi-gloss paint.
• to mask stains.The universal tool that allows you to mask the quality of the finished surface of the tough stains of nicotine stains on the ceiling leak, divorce and "rusty" stains plumbing leak.It serves as the basis for emulsion or oil paint.
• for wet spots.Decorative Primer.Do not eliminate the cause of the leakage, but good disguises gray mold stains on the walls, the ceiling inside.
• Universal.To carry out large-scale works priming heterogeneous material surfaces: concrete, brick walls, skirting boards made of wood or PVC frames of oak, ash, pine or PVC, metal and brick surfaces.

How profitable to buy primer

Presentation bargain each is at the discretion and your budget.Modern service sector in the Internet space is the most comfortable and attractive for bulk purchases, purchase small batches.All items in the online shop is supplied with detailed description of manufacturers and facilities staff.The recommendations on the use and techniques of work safety.Online Store construction chemicals suitable for people with allergies to scents.This product is presented visually in full, easily visible, but without accompanying flavors.

cost of soil depends on the brand of the manufacturer, composition and volume of packaging.For example, the Ukrainian producer offers universal primer, the price of which 5 liters or 10 kg from 15 to 30 $.Primer imported will be 5-25% higher.

quality training space for the subsequent application of the materials is an important final step to save the base coat, ignore this stage of construction and finishing work is not necessary.
