Primer consumption of 1 m2 walls: how to correctly calculate the proportions for concrete -contact and deep penetration of the primer

Using the proper primer is crucial to ensuring a smooth and durable finish when priming walls for painting. Primers are essential for strengthening adhesion, building a stable base, and stopping the topcoat from flaking or peeling. But it can be difficult to gauge how much primer is needed, particularly when working with different kinds like deep penetration and concrete-contact primers.

Concrete-contact primers are made especially for dense, non-porous surfaces like concrete. They aid in producing a rough surface that paint can stick to with ease. Conversely, deep penetration primers are designed to seep into porous materials, fortifying them from the inside out and offering a strong base for paint layers that come after.

Making an accurate calculation of the quantity of primer required for 1 m² of wall surface guarantees both the effectiveness of the application and the avoidance of material waste. Determining the proper quantity requires consideration of various factors, including the wall’s porosity, the type of primer, and the application technique. You can ensure a better painting result and save time and money by making informed decisions based on your understanding of these factors.

This post will walk you through the process of figuring out how much primer is needed for a square meter of wall space, with an emphasis on both deep penetration and concrete-contact primers. Whether you’re a professional painter or a do-it-yourself enthusiast, we’ll provide you easy formulas and helpful tips to help you get the most out of your painting projects.

A smooth and long-lasting paint job depends on knowing how to accurately calculate the primer consumption for one square meter of walls. It’s critical to understand the precise ratios required for deep penetration and concrete-contact primers on various surface types. You can maximize paint adhesion and longevity by applying primer uniformly and using the proper tools, all while adhering to a few easy steps. By following this guide, you can ensure professional results while saving time and money by determining how much primer to use.

The standards for the primer

You should be aware that primer mixtures are significantly less expensive than paint and wallpaper glue, even at small consumption.

What depends on what the primer consumption depends

The primary factor influencing costs is the type of processed surface material: porous surfaces require more material, while smooth surfaces require very little;

primer

• A set of components of the primer itself;
• Properties of material for further application;
• Environmental conditions;
• The level of professionalism of the master;
• The number of layers applied.

Which tool—a spray gun, brush, or roller—is used will determine how much coverage is covered. Reduced expenses when using a roller and, for the biggest amount, a spray gun.

Types of primer

For more dependable consolidation, deep penetration is utilized on loose, fragile surfaces.

• After application, the plane becomes smooth, the porosity decreases due to the absorption of the soil.
• The cost will be large, but the volume of finishing material will be significantly reduced.
• Such compounds are used to cover the plastered walls, wooden, from chipboard, MDF or similar materials.

Surface soils include acrylic and facade soils. produced either ready-made or in the form of powders. white in hue, making them appropriate for light coatings. Up to 150 g of volume are contained in each square meter. Acrylic paint stains work best on surfaces that have been primed by the acrylic composition.

Types of primer

• Acrylic primer is universal, suitable for any type of surfaces.
• It is good to cover wooden walls latex – perfectly protects against moisture.
• The silicone composition is intended for internal and external works, has water -repellent properties.
• Silicate or “liquid glass” tightly closes the pores of plaster and silicates, is used before painting.
• Shellakova processed raw, tarry wood.
• Polyurethane primer is covered with concrete bases, metal and ceramics.
• Alkyd serves to apply to gypsum, glass, chipboard or metal.
• Epoxy increases the strength of the coating.
• Perchlorvinyl soil due to toxicity is intended for external use.

The value of the consumption

Building material manufacturers always list the recommended usage guidelines on the packaging. However, the previously mentioned factors show that a completely accurate calculation is impossible.

The average flow rate (per square meter) varies from 10 to 300 grams, contingent upon the manufacturer and component composition.

Deep absorption primer consumption

Because of the object’s irregularities, the cost of this material is significantly higher than that of other types. However, even if you prime in multiple layers, the benefit is evident because the processed structure will continue to require much less expensive paint. High stain quality will be achieved.

Acrylic soil consumption

Two types of building materials are available for purchase: dry and ready to use.

Acrylic primer

Dry ones must be diluted with water according to the manufacturer’s recommended ratios on the packaging.

• After that, the solution can be applied to the surface, which will continue to have light shades: the color of acrylic white.
• The average norm varies from 130 to 150 g per square meter.
• Acrylic solution can be covered not only with walls, but also the floor with the ceiling.

Metal primer consumption

Something with anti-corrosion qualities is needed for the metal processing industry.

• It is obvious that water -based mixtures cannot be used.
• A good option would be the use of GF-021.
• The surface of the metal should not have rust, then the costs of the solution will be very small.
• The mixture includes epoxy resin, so it can be treated with concrete and other non -porous materials.

Landing for metal

On an unprepared plane, use will increase, but 110 g is sufficient for 1 square meter of wall.

Latex primer consumption

Artificial latex is water-repellent and elastic, but it lacks adhesive qualities. Wood and composite materials are used for loose and crumbling coatings.

The primer is latex

Can be painted 1.5 hours after use and dries in 40 minutes. Up to 220 grams are consumed on average per square meter.

A smooth, long-lasting finish on your walls depends on accurately calculating the amount of primer you need. It’s crucial to understand that the purpose of concrete-contact primer is to increase the finishing materials’ ability to adhere to concrete surfaces. The usual consumption rate varies from 300 to 500 grams per square meter, contingent upon the porosity and roughness of the surface. Try doing a small test area first to find out the precise amount required.

The consumption rate for deep penetration primers, which are used to stabilize and strengthen porous surfaces, typically ranges from 100 to 200 grams per square meter. These primers go far into the substrate, sealing it and giving later layers a strong foundation. To guarantee uniform coverage, it’s critical to adhere to the manufacturer’s instructions and apply the primer evenly.

A successful application depends on precise primer measurement and mixing. Make sure you mix ingredients according to the recipe by using measuring tools, and make sure you thoroughly read the product instructions. Excessive or insufficient primer application can have an impact on the outcome, resulting in product waste or inadequate preparation.

You can make sure that your paint job not only looks fantastic but also endures over time by being aware of the unique requirements of your wall surfaces and adhering to the primer consumption guidelines. A solid foundation for any paintwork is created by careful preparation using the appropriate primer, assuring longevity and visual appeal.
