Reviews of site visitors:
Acrylic materials were not often encountered.
First of all, these were acrylic varnishes, which were positioned as varnishes, which, unlike polyurethanes, do not turn yellow over time. Basically, it turned out that way. But there were downsides acrylic materials cost more and dried longer, which is critical when the deadlines for painting and poor heating paint area. And if the varnish has not dried properly, then there are problems with its polishing, the varnish begins to roll.
Secondly, I had to work with acrylic paints, when there were problems with metallic paint, which was made on the basis water paint. The paint supplier offered to make a metallic based on acrylic paint and, as time has shown, this was the right choice.
There is a misconception about what is acrylic facades. Acrylic facades are called furniture facades, which are covered with acrylic plastic, plastic and paint are different things. So, do not get confused about what acrylic facades are.

The article compares alkyd and acrylic primer, the main differences between the compositions are revealed. It describes the compatibility of paints with each other and which one is more suitable for covering wood.
Composition comparison
The basis of acrylic paint is a polymer emulsion - acrylic mixed with pigments. The solvent is ordinary water, so the material does not have a strong odor. Acrylic is known as water glass and is used as a binder in other building mixtures. It also includes improving additives that affect the viscosity, temperature stability of the solution, the finished coating.
Alkyd, or oil, enamel consists of alkyd varnish, coloring pigments, kerosene solvent (white spirit). Additional additives may be included: antiseptics, antifungals, fire-fighting additives. This enamel is often used to coat wood products. When working, thorough ventilation of the premises is required: the composition has a sharp specific smell.
Features of alkyd paint
You can find varnishes and paints.
The varnish is based on alkyd and solvents. It contains no pigments. The solution is used as a primer for other finishing coatings, wood preservative.
The paint contains pigments. Can perform the function of surface protection. It can be glossy, matte, it does not affect the quality of the coating.
Varnish and primer of the same base have good compatibility. They can be applied on the same surface, mixed.
Advantages
- Wide color range.
- Ease of application, good distribution over the surface.
- Layers dry quickly.
- Cleaning resistance.
- Suitable for interior and exterior work.
- Affordable price.
disadvantages
- Strong smell.
- Low UV resistance. The coating fades quickly in the sun.
- Hardness negatively affects the service life. Dried enamel is inelastic, does not withstand linear expansions of the surface. After a few years it cracks and needs updating.
If you need to use alkyd paint on the street, you should choose a composition with additives. The painted product is best placed in the shade.
Acrylic paint: features of use
Acrylic polymer is plastic. The dried coating layer is able to stretch, shrink when minor changes base dimensions. The paint does not crack after frost. So that the composition lies well on the surface wooden product, necessary:
- Remove the old coating from the base, sand the surface.
- prime material special formulations to prevent decay, reproduction of pests.
The basis for acrylic should be dried, cleaned of dust. Coloring composition diluted with plain water, applied to walls, ceilings, products with a brush, roller. Paint is well distributed on the prepared basis.
Advantages
- Does not change color in the sun, at high temperatures.
- Due to the elasticity, the coating does not peel off, does not crack.
- Long service life - at least 8 years for wood, about 20 for metal and plaster;
- The composition protects the surface from moisture, corrosion.
- No strong odor. Paint does not highlight harmful substances, it is safe to work with it even without protective equipment.
disadvantages
- High price.
- The long period of a set of operational durability - about a month.
- Good, qualitative composition difficult to find.
Main differences
Material properties are presented in the table.
Dye Compatibility
There is no need to combine ingredients. Alkyd - good primer for wooden surfaces. Also suitable as a top coat if applied in several layers.
Acrylic paint is elastic, it is best used on products that are subject to linear expansion due to temperature changes, changes in humidity.
Is it possible to combine enamels
To work on the same surface, you need to use tools on the same basis.
Soft formulations can be applied to hard coatings, but not vice versa.
Alkyd enamel is hard, works as a primer under a varnish layer or more soft cover . Acrylic is a flexible covering material. Can be applied over oily, dry or old foundations. But in this case, the service life of the finishing layer is reduced by 2 times.
The combination is suitable for wood. On surfaces made of other materials, it makes no sense to mix layers.
What Not to Do
Should not be applied alkyd enamel on the acrylic surface. If this is still necessary, you need to remove the old coating to the maximum, sand it thoroughly, then prime it.
Do not mix dissimilar components. Acrylic-alkyd enamel can only be produced industrially special technologies. It is not used in construction.
Conclusion
The article compares two materials. You can't say which one is better. When choosing, you need to take into account the expected service life of the coating, operating conditions, the quality of the finished surface, and the budget for repairs.
Paints and varnishes are applied to the surface to be protected, as a rule, in multilayer systems, which may consist of primers, putties, enamels. for various purposes. At the same time, the paintwork materials included in the system can be heterogeneous not only in terms of the pigment part, but also in terms of the film-forming base, but they must be compatible with each other. ISO 12944-5 defines paint compatibility as the ability of two or more paint materials to be used in a coating system without undesirable effects. The use of materials with incompatible binders and solvents that do not provide the necessary interlayer adhesion or a high-quality uniform layer-by-layer coating leads to the need to remove a poor-quality coating and repeat the preparatory and painting work.
When formulating coating systems, it is best to use materials with one type of binder. This is especially true for chemical curing materials (epoxy and polyurethane). To ensure the necessary interlayer adhesion when applying these materials on them, it is necessary to follow the recommendations for the intercoat drying time very accurately. Epoxies and polyurethanes contain very active solvents (xylene, acetone, cyclohexanone), so these materials cannot be applied over reversible physical curing coatings (chlorinated rubber, vinyl, copolymer-vinyl chloride, nitrocellulose, etc.), because dissolution of reversible coatings and formation of defects can occur. When applying epoxy or polyurethane coatings to materials that cure with oxygen in the air (alkyd, oil), swelling and sub-dissolution of these coatings and delamination of the entire coating from the metal can occur.
Polyurethane top coats can only be applied over polyurethane, polyvinyl butyral or epoxy primers and top coats, subject to intercoat drying conditions to ensure intercoat adhesion. Epoxy enamels can only be applied over epoxy, polyvinyl butyral, zinc silicate and ethyl silicate primers and enamels.
Silicone and silicate paints and varnishes are not recommended to be applied over any other types of paints and varnishes, because. most of them are heat curing materials.
Alkyd and oil enamels can be applied on almost all physical curing paints and varnishes, except for bitumen and pitch. In the case of using alkyd and oil enamels on coatings containing bitumen and pitch, the latter may migrate to the upper layers and change their color.
Vinyl, copolymer-vinyl chloride and chlorinated rubber materials can be applied over polyvinyl butyral, acrylic, epoxy ester, zinc silicate and epoxy materials.
When choosing paints and varnishes for repairing coatings after operation, it is first necessary to clarify the paints and varnishes used in the previous painting.
When repairing, it is better to use the same paints and varnishes as in the previous painting or similar ones (on the same binder).
To eliminate errors, it is best to use the experimentally verified recommendations given in technological instructions or other documents related to this material.
Generalized experimental data on the compatibility of coatings on various film-forming bases are presented in Table. one.

Notes:
“+” - you can apply
“-” - can not be applied
“number” - can be applied with the following restrictions:
1. In case the epoxy ester film former is diluted
white spirit;
2. If bitumen and pitch do not penetrate (do not migrate) to the surface
3. When applying anti-fouling enamel, it is advisable to use
intermediate layer to prevent the diffusion of toxins into the bituminous
(pitch) underlying layers;
4. After adhesion test due to the variety of incoming solvents;
5. After roughening the coating or tack;
6. After operation for at least 3 months.
When choosing shop (factory) primers, it is necessary to take into account their compatibility with those used in further systems coatings. For right choice table should be followed. 2. (recommendations of ISO 12944-5).
