Oil-adhesive putty: what is it and what is it used for

One versatile material that is essential for getting walls and ceilings ready for finishing is oil-adhesive putty. This putty, which is well-known for having outstanding adhesive qualities, is frequently used to fill in small gaps and smooth out surfaces in order to provide a perfect foundation for decorative finishes like paint or wallpaper.

This kind of putty is especially appreciated for how long-lasting and simple it is to use. It is created by mixing adhesive ingredients with either synthetic or natural oils to create a paste that adheres strongly to a variety of surfaces. Oil-adhesive putty can facilitate the creation of a smooth, even layer that improves the overall appearance of your walls, regardless of whether you’re working with plaster, wood, or drywall.

The flexibility of oil-adhesive putty is one of its main advantages. Because it can be applied to both exterior and interior projects, many professionals and do-it-yourselfers turn to it as their go-to choice. You can get a long-lasting, high-quality finish with this putty, even in places that are subjected to moisture or temperature changes.

Property Description
What is it? Oil-adhesive putty is a type of filler made from a mixture of drying oils, adhesive components, and fillers. It"s used to create smooth surfaces on walls and ceilings before painting or wallpapering.
Usage It"s applied to cover small cracks, holes, and imperfections on various surfaces, ensuring a clean and even base for finishing work.

About the material

Any putty is defined as a viscous thick mass based on different binders with the addition of pigments and fillers to improve the material’s properties, as per the current GOST 10277 90.

Composition of oil-adhesive putty

Drying oil serves as the material’s binder. The ensuing serve as fillers:

  • CMC glue;
  • Chalk;
  • Plasticizers that ensure ease of application of the composition to the surface;
  • Drying agents that accelerate the drying of oils;
  • Water.

Additionally, every manufacturing facility has the option to add different thickeners, antiseptics, modifying additives, and pigments to give their products a specific color.

Characteristics

For interior work, putties with oil adhesive are utilized. primarily for leveling surfaces made of wood, plaster, and concrete that will be painted with enamels, oil, and water-dispersion paints (see Paint for Interior Wall Decoration: How to Select). Technical features of oil adhesive putty:

Binder Drying oil
Appearance Pasty mass, homogeneous, without foreign inclusions
Consumption On average 0.8-1.5 kg/m2 with a layer thickness of 1 mm
Dry residue 68-80%
Drying time Between layers – 3-4 hours, final – no more than 24 hours
Layer thickness 1.5-2 mm
Storage conditions At temperatures above 0 0 in a tightly closed container. One-time freezing is allowed not lower than -25 0
Shelf life 6-12 months

As a point of reference. The features of this putty may vary slightly because each manufacturer makes products that adhere to the technical specifications used during production.

Advantages and disadvantages

The primary benefit of the material is its universality; its composition, technical properties, and strong adhesion enable it to be applied to a variety of surfaces, including wooden window frames, door blocks, plastered or plasterboard walls, floors, and wooden window frames (see Floor finishing: types of material). The following qualities are among the additional benefits:

  • Plasticity, ease of application and processing;
  • Fast drying, reducing technological breaks between different stages of finishing works;
  • Durability;
  • Harmless composition, eco-friendliness;
  • Low price – compared to other putties, oil-glue is the cheapest.

However, there are significant drawbacks to this material that prevent it from being used for outdoor work or finishing surfaces that are subjected to high mechanical loads and moisture. As previously mentioned, the following are some of this composition’s drawbacks:

  • Insufficiently high strength and resistance to mechanical damage;
  • Instability to high humidity and direct exposure to moisture;
  • Short shelf life – with long-term storage, the material loses its plasticity. And with prolonged exposure to low temperatures or repeated freezing, it becomes completely unsuitable for use.

It should be noted that this putty has very specific application requirements. The directions state that the putty should be worked with at a minimum temperature of 10-15 degrees (the ideal temperature is 20-22 degrees) and a maximum air humidity of 65-70%.

A versatile tool for smoothing and priming surfaces before painting or wallpapering is oil-adhesive putty. It’s perfect for leveling uneven surfaces, caulking gaps, and giving walls composed of plaster, concrete, and wood a sturdy foundation. This putty is a popular option for both professional and do-it-yourself projects because it is simple to use, long-lasting, and guarantees a smooth finish.

Application technology

Read through the safety requirements before beginning work. Put the paste on in a well-ventilated area while wearing rubber gloves to protect your hands’ skin.

Kindly take note. Oil compositions should never be placed close to an open flame because they burn easily.

Preparatory stage

Examine the surface with great care. Large cracks and other flaws that are deeper than 4–5 mm need to be plastered. The entire area that is going to be finished is primed once the solution has dried.

If the surface has an old oil paint layer on it, it needs to be cleared of dust and primed (see "Primer consumption per 1 m2" for approximate data on how much paint is needed). It also needs to be cleaned as much as possible to remove the peeling coating using coarse sandpaper.

As a point of reference. You can use either pure drying oil or latex diluted 6:1 with water as a primer.

Once the package is opened, the material is well mixed. GOST permits you to dilute too-thick universal putty with drying oil to get the right consistency if you receive it.

Main stage

After preparation, dust removal, degreasing and priming, the surface must be allowed to dry. Then apply the putty in the usual way, using a metal or rubber spatula. It is easy to apply with your own hands thanks to its plasticity and the ability to independently bring the mixture to a consistency convenient for you.
Putty is applied with a layer of no more than 2 mm. If it is not enough for leveling, then the required number of layers is performed, but each must harden before applying the next one.
To do this, it is enough to wait 3-4 hours, and lay the second layer in the direction perpendicular to the previous one, having previously sanded and dusted the surface.

After puttying, the base is sanded with fine sandpaper or a grater 7-8 hours later to create a perfectly smooth surface. After 24 hours, the putty reaches its full strength and the surface hardens completely, making sanding much more challenging. Any deep penetration primer must be used to prime the putty base once more in order to stop oil stains from later showing through the decorative finish.

A versatile and dependable material that is essential to wall finishing is oil-adhesive putty. Because of its special makeup, it can adhere to a variety of surfaces and form a strong, even surface for painting or wallpapering. Whether you’re trying to achieve a flawless finish, dealing with uneven surfaces, or cracks, oil-adhesive putty can be a great option to get professional results.

The ability of oil-adhesive putty to stick to difficult surfaces, especially those with high moisture content, is one of its main benefits. Because of this, it’s especially helpful in spaces like kitchens and bathrooms where other materials might find it difficult to hold up over time. Its simplicity of use also means that both seasoned pros and do-it-yourselfers can get excellent results with little difficulty.

In conclusion, oil-adhesive putty provides a workable option for anyone wishing to improve the caliber and aesthetics of their walls. Because of its strong adhesive qualities and adaptability, it is the preferred choice for a variety of wall finishing projects. Whether preparing a new space or remodeling an old one, this putty can assist you in getting the even, smooth surface you want.
