Bonding agents are essential for enhancing the adhesion between a paint coating and the underlying surface. They are primarily used to improve the adhesion of coatings on hard-to-coat surfaces, such as concrete, brickwork, and vinyl siding, as well as surfaces with an increased risk of peeling, chipping, or coating failure. These agents can be in the form of primers, resins, or powders, and they serve to create a robust bond, improve durability, and extend the functional life of the paint.

Bonding agents are used to enhance adhesion between paint and the underlying surface, preventing peeling and chipping
One example of a bonding agent is a primer, which is applied to a surface before painting to improve adhesion and create a smooth surface for the paint to attach to. Primers come in various types, including oil, shellac, and latex, each with its own advantages and disadvantages. Bonding primers are specifically designed to stick to glossy or sealed surfaces and block stains, making them ideal for covering questionable areas. They can also help lock down peeling paint and smoothen the surface to prevent visible peel barriers.
Another type of bonding agent is the Slip Doctors Bonding Agent, which is designed to maximise adhesion on surfaces that are hard to coat or at risk of peeling and chipping. This product is mixed into the first coating batch and is compatible with various coatings, including urethanes, epoxies, and paints. It increases the functional life, corrosion resistance, appearance, and sealer qualities of the coating.
Additionally, eco-friendly paint bonding agents are available, such as the BioPowder Olea FP, which is made from olive stones. These bonding agents can act as additives in resins and coatings, providing strong adhesion and durability. They are also customisable to improve binding power and adhesion, especially in solvent-free formulations.
In construction, bonding agents like PVA Bond are used to adhere to common building materials. PVA Bond is a multipurpose primer, sealer, and adhesive that can be used on porous surfaces such as wood, cork, and textiles. It is also effective for dust sealing on flaking paintwork walls and as a cement and plaster admixture.
Overall, bonding agents play a crucial role in enhancing adhesion, preventing peeling and chipping, and improving the durability and longevity of painted surfaces.

They can be used on hard-to-coat surfaces such as metal, porcelain, concrete, and previously coated floors
Bonding agents are used to enhance the adhesion between a paint coating and the underlying surface. They are particularly useful for hard-to-coat surfaces, such as metal, porcelain, concrete, and previously coated floors. These surfaces often present challenges to adhesion due to their smoothness, glossiness, or previous treatments.
Metal surfaces, for example, can be challenging to coat due to their smoothness and, in some cases, their glossiness. Bonding agents can help promote adhesion and create a more stable coating. Similarly, porcelain surfaces, especially those with a high sheen, can be difficult to coat effectively. Bonding agents can improve the adhesion of coatings and paints to these surfaces, reducing the risk of peeling or chipping.
Concrete is another hard-to-coat surface. When applying new concrete over old concrete, a bonding agent helps to join the two together, resulting in a more stable structure. Bonding agents can also be used to improve the adhesion of paints or coatings to concrete surfaces, making them ideal for use in flooring applications.
Previously coated floors can also benefit from bonding agents. These agents can be used when overcoating previously sealed or coated surfaces, as they promote adhesion and reduce the risk of peeling. They are suitable for use on floors that cannot be sanded or etched and help extend the functional life of the coating.
Overall, bonding agents play a crucial role in enhancing the adhesion of paints and coatings to hard-to-coat surfaces. By improving adhesion, bonding agents help create more durable and long-lasting finishes, reducing the need for frequent maintenance or repairs.

Eco-friendly alternatives are available, made from olive stones, offering a sustainable and biodegradable option
Bonding agents are used to enhance the adhesion of paint coatings to surfaces. They are particularly useful for hard-to-coat surfaces or surfaces with an increased risk of peeling, chipping, or coating failure.
Traditionally, bonding agents are mainly resins, such as epoxies, that facilitate the adherence of a coating to a surface material. However, there is a growing demand for eco-friendly alternatives to traditional bonding agents, as consumers become increasingly aware of the potentially harmful effects of synthetic glues and chemicals.
BioPowder offers an innovative range of biological bonding powder additives for paint bonding applications. Their Olea FP (Functional Powders) are 100% made from top-grade olive stones, a sustainable by-product of the olive oil industry. These powders can be used to create bonding paint that can be applied directly to any surface, without the need for prior sanding or application of a primer. They can also improve foundations and undercoatings while boosting the bio-based percentage of their components. The low-density particles of Olea FP can easily migrate on the surface and create an optimised adhesive particle flow, improving binding power and adhesion.
In addition to olive stones, BioPowder's products also utilise almond shells and other agricultural by-products, such as wood adhesives or wood repair products, to create natural bonding additives. These eco-friendly alternatives not only enhance adhesion but also contribute to environmental preservation and support the broader objectives of reducing environmental impact and promoting sustainability.
Another company, Mylands, also offers an Olive Stone Emulsion paint with 56% bio-based content. This paint contains ground olive stones and is produced locally in London, reducing their carbon footprint and emissions.

Bonding agents are also used in construction to join new and old concrete, creating a stable structure
Bonding agents are an essential component in enhancing the adhesion between a paint coating and the underlying surface. They are designed to increase the functional life, corrosion resistance, appearance and sealer qualities of paints. For example, SlipDoctors' Bonding Agent improves adhesion on surfaces that are hard-to-coat, reducing the risks of peeling or chipping.
In construction, bonding agents are used to join new and old concrete. This is achieved by applying the bonding agent to the old concrete, which then helps to join the new concrete, creating a melded, stable structure. This is similar to the function of glue, but bonding agents are used in a different manner to standard adhesives.
Bonding agents are also used as primers, which are applied to surfaces prior to painting. Primers provide a smooth surface for the paint to adhere to and come in three types: oil, shellac, and latex. Bonding primers are particularly useful for covering questionable areas and blocking stains. They can also be used to lock down peeling paint and smooth surfaces.
Overall, bonding agents are an important tool in construction and painting, helping to create stable structures and enhance the adhesion of coatings.

Bonding primers are a type of bonding agent that can block stains and cover peeling paint
These primers are applied directly to the surface before painting, creating a coating that the paint can adhere to. They are particularly useful when dealing with surfaces that are hard to coat, such as those that cannot be easily sanded or etched, or when there is a risk of coating failure. By using a bonding primer, you can improve the durability of the paint job and prevent issues like peeling or chipping.
One example of a bonding primer is the Valspar brand, which offers a product specifically designed to stick to glossy or sealed surfaces and block stains. Other primers, like the Rust-Oleum brand, recommend applying the topcoat within a week of priming to ensure optimal adhesion and durability.
In addition to ready-made primers, there are also bonding agents available that can be mixed into the paint itself. These products are designed to maximise adhesion and are compatible with a wide range of coatings, including urethanes, epoxies, and paints. They can be used on various surfaces, such as metal, concrete, and porcelain, and help to extend the life and functionality of the paint job.
Overall, bonding primers and agents play a crucial role in ensuring the successful application of paint to a variety of surfaces, providing a durable and long-lasting finish. They are an essential tool for anyone looking to achieve a high-quality and professional paint job.
