Primer consumption per 1 m2 – approximate data for determining the required volume

One of the most important things to think about when organizing a wall finishing project is how much primer you’ll need. In order to ensure that paint or other finishes adhere correctly and last longer, primer is necessary for surface preparation. How much primer, though, is enough? Here’s where knowing how much primer is used per square meter becomes essential.

A number of variables, including the kind of surface, its state, and the particular primer used, can affect how much primer is used. Knowing roughly how much primer you’ll need can save you time and money by preventing needless trips to the store and guaranteeing you have enough to finish the job without interruption.

We’ll give you an idea of the approximate primer consumption per square meter in this article, so you can use it as a helpful guide to estimate the volume needed for your project. You’ll save time and money by using this information to estimate the proper amount of primer, whether you’re working on a small DIY project or a larger renovation.

Type of Primer Approximate Consumption per 1 m²
Acrylic Primer 100-150 ml
Deep Penetrating Primer 120-200 ml
Universal Primer 150-250 ml
Concrete Primer 200-300 ml

Choosing a primer and determining its quantity

Among the factors governed by GOST are primer consumption for walls, ceilings, and other surfaces composed of various materials, as well as density, viscosity, color, and total drying time. The same document governs primers’ use and the extent to which they can be applied based on their composition.

Types of soil

Primer can be used on plastered surfaces, metal or wood, concrete or brick walls, and drywall (see Primer for drywall: how to do it right). Moreover, they are unique and versatile, appropriate for handling a range of materials. Thus:

  • Acrylic primer is considered universal for many surfaces. The most popular of them today is the primer Ceresit ST 17 – the consumption of this product depends on what material is being processed (concrete, cement, brick, asbestos, wood, plaster, etc.).Acrylic compounds are non-toxic, odorless, if necessary, they can be diluted with water;

Kindly take note. Because it cannot stop the corrosion of ferrous metal surfaces, this primer is not appropriate for use on such surfaces.

  • For wooden surfaces – floors, doors (see.Door finishing: which material to choose), window frames, walls and partitions made of chipboard, fiberboard or OSB, use an alkyd primer, which includes synthetic resins that create a strong base for alkyd paints. It is also suitable for processing metal, but it does not “get along” with gypsum or cement plaster at all;
  • To protect metals (pipes, fittings, water tanks) from corrosion, as well as to treat concrete before installing self-leveling floors, use epoxy primer;

Crucial! Paints that are designed to be applied to surfaces should be considered; epoxy paints will work best on this type of base.

  • For external impregnation of brick, concrete and decorative plaster surfaces, it is best to use silicate primer. Its alkaline environment is lethal to microorganisms, so it can be used in rooms with high humidity;
  • For better adhesion to the roof base of fused waterproofing materials, as well as for saturating concrete surfaces, use bitumen primer – its consumption is the highest, and the product itself is toxic and extremely flammable. Therefore, it is necessary to use protective equipment and observe safety measures to work with it.

Suggestions. Buying a universal product that works on any surface is the most convenient option if you plan to process different surfaces.

It would be wise to research local material availability in your area by looking into construction markets before attempting any repairs yourself. A single manufacturer frequently sells a range of surface finishing products, including primers, paints, wallpaper glue, plaster and putty mixtures, and more. The instructions go into great detail about the application technology and consumption rates, and their use ensures excellent material interaction. Of course, you can purchase all the required blends and compositions from various brands, but in this instance, you must pay close attention to how well they work together.

Consumption rates

The packaging always states the rate of consumption. It is important to note that the amount of product required for a square meter is only an estimate, as it is contingent upon the surface’s absorbency and processing frequency. It is evident from watching the video in this article that priming is sometimes done in three layers. The first is nearly entirely absorbed by the material, and the ones that follow establish a strong foundation for additional finishing. Important factors to consider are the master’s credentials and the primer application technique (brush, roller, or spray). However, these standards are generally as follows:

  • The consumption of Betonokontakt primer per 1 m2, applied to dense bases and characterized by high adhesive properties, is 300-400 ml / m 2 ;

  • The primer used to prepare the base for decorative plaster is consumed at the rate of 200 ml / m 2 ;
  • Universal, deep penetrating acrylic primer – consumption per 1 m2 is only about 100 ml/m2;
  • The consumption rate of alkyd primer for wooden surfaces can be from 100 to 200 ml / m 2 depending on the order of application and the absorbency of the base;
  • Consumption of primer GF 021 per 1 m2 on a metal surface is on average about 120 ml/m2;

  • Consumption rate of silicate facade primer – from 100 to 150 ml/m2;
  • The least amount of primer will be needed to treat galvanized metal – 80 ml/m2 .

It is essential to comprehend the amount of primer used per square meter when organizing any wall finishing project. To help you avoid costly mistakes and make sure you buy the right amount of primer from the start, this article offers simple instructions on estimating the amount needed for various surfaces.

The secret to getting a smooth and durable finish on your project is knowing how much primer you’ll need. Estimating the amount of material used per square meter will help you plan your work effectively and prevent mid-work material shortages.

Keep in mind that the amount of primer you use can vary based on a number of factors, including the kind of surface, the state of the wall, and the particular product you’re using. For a more precise estimate, you can perform a small test patch and consult the manufacturer’s recommendations.

By keeping these things in mind, you’ll be more equipped to buy the appropriate quantity of primer and save money and effort. Planning ahead will guarantee that your walls are ready for the finishing coat, producing a more polished and long-lasting outcome.
