What is the best putty for chipboard for interior work (for painting)

The correct putty can make a big difference when it comes to priming chipboard surfaces for a new coat of paint. Because of its uneven and porous surface, chipboard needs a particular kind of putty to give a smooth, polished finish. However, it can be a little overwhelming to choose the best option for interior work because there are so many available.

Putty fills in any holes, fissures, or flaws in the chipboard to produce a perfect surface for painting. You’ll want a putty for interior projects that dries fast, sticks well, and sands easily to a fine texture. This improves the paint job’s durability in addition to helping to achieve a flawless finish.

The best putty types for chipboard will be discussed in this guide, along with things to look for in the selection process. We’ll go over the important factors to take into account to help you achieve the best results for your painting project, from drying times to ease of application. Let’s get started and choose the ideal putty to enhance the appearance of your chipboard surfaces!

Is it possible to plaster sheet materials

Chipboards are used for rough finishing; they can be used to equip partitions, level walls and ceilings, and form a prefabricated screed. Depending on the nature of the ensuing work, it is decided if chipboard can be puttied.

Chipboards need to be primed, puttied, and plastered before decorative finishing is applied to interior spaces. Putty is required to fix chips, seal cracks, and seal joints. You can apply wallpaper to a variety of surfaces after plastering.

  • leveling the base;
  • increasing the strength of the walls;
  • elimination of cracks, height differences;
  • protection of chipboard from mold, mildew, decay;
  • improving surface adhesion;
  • increasing the vapor permeability of the base.

The pasted wallpaper may peel off the chipboard if putty and other mixtures are not applied, and uneven painting will show.

Advantages and disadvantages of putty for chipboard

  • high elasticity;
  • good vapor permeability;
  • increased strength;
  • moisture resistance (except gypsum).
  • acrylic – used only to cover the base for wallpaper;
  • oil – dry for a long time;
  • latex – belongs to the category of expensive;
  • epoxy – complex in preparation and application.

Varieties of plaster: how to do work

A suitable material is chosen before the chipboard is hung, taking into account the type of work (internal, external), the room type (living room, children’s), the design, the method of decorating that will come after, the humidity level in the air, etc.

  • oil;
  • latex;
  • oil-glow;
  • polyester;
  • acrylic;
  • epoxy.

Oil and oil-adhesive

Drying oil is used as a binding agent in these solutions.

  • chalk;
  • siccatives;
  • CMC glue;
  • plasticizers;
  • water.
  • modifying components;
  • coloring pigments;
  • thickeners;
  • antiseptic substances.

Putties made of oil are made in plastic bags or containers as paste-like mixtures. The putty is composed uniformly and consumes little. Applying a 1 mm thick solution will result in 0.8–1.5 kg of consumption per 1 m². The coating dries quickly (in 3–4 hours), is easy to apply, and has increased plasticity. The material application should not be thicker than 2 mm.

Depending on storage conditions, the mixture has a shelf life of six to twelve months. The material is safe to use and long-lasting.

Unfortunately, the composition’s low resistance to moisture and mechanical damage makes it unsuitable for facade work.

Latex

Fillers, water, modifying agents, and plasticizers are all present in the material. As a binder, latex is employed. Antiseptic ingredients are often included in mixtures of this kind to stop mold and mildew from growing on the treated surface.

Because latex putty contains polymer components, it can help you form an even and smooth surface. The base can be prepared for painting by applying the mixture. A thin, even layer of the material that is long-lasting can be applied.

  • minimal shrinkage after drying;
  • no cracks after drying;
  • high adhesion;
  • easy application, layer thickness does not exceed 1 mm;
  • the material is available in a wide range of shades;
  • manufacturers produce latex compositions in packages of different volumes;
  • the coating forms a film that protects surfaces from dirt, dust, prevents cracking and rapid wear.

Polyester

Such putty for chipboard is made of polyester masses, fillers, and resins.

  • fiberglass;
  • Glass microgranulas;
  • aluminum powder powder;
  • hardener;
  • plasticizers, etc..

The material’s high performance characteristics are derived from a unique formula.

Aluminum powder is added to polyester putty mixtures to produce them. The addition gives the coating wear resistance and strengthens the composition’s resistance to temperature increases.

Inconsistencies are filled using polyester mixtures containing medium-grained filler. The putty layer should not be thicker than 3 mm in order to avoid the coating shrinking.

Acrylic copolymers

These mixes are also among the easiest to use when getting ready to finish wood-fiber boards. The materials are used to process interior spaces and facades and are widely available.

  1. It has a high level of adhesion to decorative coatings (facing boards, wallpaper, paints).
  2. Helps to correct irregularities, differences in height.
  3. Increases moisture resistance of wood boards, shelf life, ensures maintenance of the aesthetics of subsequent finishing.
  4. Increases resistance to changes in temperature conditions. Acrylic putty mixtures protect the coating from direct sunlight, frost, increasing the service life of decorative finishing.
  5. Enhances the mechanical strength of the chipboard base.
  6. Increases the thermal insulation of treated surfaces.

Epoxy resin

The substance is a two-component blend created by combining a hardener and resin. Filler materials include metal shavings, metal dust, and fiberglass. The material works well for painting the base coat.

Epoxy resin that is transparent lets you highlight the wood-fiber boards’ structure. Small imperfections and cracks are concealed by the resin, which also creates a glossy, smooth surface. The proportions listed on the packaging are followed when diluting the two-component mixture.

How to prepare chipboard surfaces

Prior to applying putty to chipboard, you must select the material, layer thickness, and finishing technique. Different technologies are used to process bases for painting and adhering wallpaper, leveling walls and ceilings, and getting furniture ready for furniture tinting.

For painting

Wood-fiber boards are carefully processed with sandpaper or an abrasive mesh to prepare the base for painting. Sheathing and frame assembly is followed by sanding. The surface needs to be flawless, free of cracks and height variations, as paint cannot fix base imperfections. Pre-priming the bases in multiple layers is required for a strong putty fix.

  1. The seams between the boards must be carefully filled with putty. Deep penetration compounds are used to process the seams.
  2. Along the edges of the chipboard sheets, the joints are hidden with finishing materials.
  3. After eliminating the irregularities, fiberglass tape or painter"s mesh is applied to the joints and seams.
  4. Putty is applied to the walls before painting in 2-3 layers no more than 3 mm thick.
  5. Surfaces are processed only after thorough drying, sanding, cleaning from construction dust.

Under the wallpaper

The base needs to be covered with two layers of putty mixture before the sheets are adhered to. Using a specialized spatula, the composition is evenly distributed and the outer and inner corners are handled with care. From the corner sections to the wall’s center, movements are made.

Sand the wall after the substance has solidified. Chips and irregularities are removed with abrasive materials. Applying the initial layer of the solution requires using a steel spatula.

Selecting the appropriate putty for chipboard painting preparation is essential to a smooth, polished finish. The best putty for chipboard work inside the house is the kind that dries to a smooth, sandable surface and sticks well, filling in gaps and imperfections. An acrylic or latex-based putty that is lightweight and dries quickly is perfect for most DIY projects. It’s ideal for chipboard’s often uneven surfaces because it offers excellent adhesion and flexibility, as well as ease of application and cleanup.

Choosing a primer for chipboard

  • surface leveling;
  • increasing wear resistance;
  • improving adhesion;
  • protection against rot, mold.

  1. Facade work – for finishing wooden facades, a mixture with moisture-resistant characteristics is selected, resistant to changes in temperature conditions, sunlight. These compositions contain antiseptic components that prevent the appearance of mold, fungus.
  2. In interior spaces with dry air, you can use universal compositions or mixtures for processing wood boards.
  3. In rooms with high humidity (bathrooms, toilets), compositions with antifungal fillers are used. Deep penetration solutions are optimal for enhancing surface protection.
