Important Installation Considerations

For the best results, the surfaces being bonded should be clean, sound and suitable for adhesive application. Existing coatings, paint, dirt, grease or other contaminants can affect adhesion and should be considered before installation.

The adhesive should be used in accordance with the relevant application instructions for the product and the specific installation.

Good to Know

We have not listed curing times, coverage rates, temperature limits or bond-strength figures because these specifications were not included in the product information supplied to us. This avoids giving you figures that may not accurately reflect the product.

From the Mats4U Team

If you're specifying adhesive for a particular GRP installation, look at the whole application rather than the adhesive alone. The substrate, GRP product, surface condition and fixing requirements all need to be considered together.

One of the main advantages of GRP Adhesive and Sealant is its versatility across different substrates. It is designed to bond GRP to a range of commonly encountered surfaces, making it suitable for different anti-slip GRP installation projects.

Metal

The adhesive can be used to bond GRP products to metal substrates, providing an alternative to mechanical fixing where an adhesive installation is appropriate.

Wood

GRP can also be bonded to wood, making the adhesive useful for applications involving timber steps, decking or other suitable wooden surfaces.

Concrete

For concrete substrates, the adhesive provides a bonding method for securing suitable GRP products without relying solely on mechanical fixings.

The concrete surface should be sound and suitable for bonding, with dust, dirt and loose material removed before application.

Brick

The adhesive can also be used to bond GRP to brick, providing another option for installations where the GRP needs to be attached to masonry.

Preparing the Substrate

Regardless of the substrate, preparation is an important part of achieving a good bond. Surfaces should be:

• Clean and free from loose dirt or debris
  
• Sound and stable
  
• Free from contaminants that could interfere with adhesion
  
• Suitable for receiving an adhesive
  
• Prepared according to the adhesive application requirements

Good to Know

“Suitable for metal, wood, concrete and brick” does not mean every surface within these categories will bond equally well. Paint, coatings, contamination, dampness and the condition of the substrate can all affect adhesion.

From the Mats4U Team

If you're bonding GRP to an existing painted, coated or particularly smooth surface, don't assume the adhesive will bond directly to it. Check the condition of the surface and prepare it appropriately before installation.

Remains Flexible Once Cured

GRP Adhesive & Sealant is designed to remain flexible once cured, rather than creating a completely rigid bond. This flexibility can be useful when bonding GRP products to substrates that may experience some natural movement during everyday use.

The product combines adhesive and sealant properties associated with silicone and polyurethane technologies, providing a bonding solution that is designed to maintain flexibility after curing.

Why Flexibility Matters When Bonding GRP

GRP products are often installed onto different materials, including metal, wood, concrete and brick. These materials can behave differently, particularly where there are changes in temperature, movement or everyday loading.

A flexible adhesive can help accommodate a degree of movement between the bonded surfaces while maintaining the connection. However, flexibility does not mean the adhesive can accommodate unlimited movement, so the condition of both the GRP product and substrate remains important.

Clear Finish for a Discreet Installation

GRP Adhesive & Sealant is available in clear, making it a practical choice where you want the adhesive to remain visually unobtrusive around an anti-slip GRP installation.

This can be particularly useful when the appearance of the finished installation matters, while still providing a dedicated bonding solution for compatible GRP products.

Good to Know

A flexible adhesive should still be applied to suitable, properly prepared surfaces. Flexibility helps accommodate movement, but it does not compensate for an unstable substrate or poor surface preparation.

From the Mats4U Team

When planning an adhesive installation, consider how much of the GRP product will be in direct contact with the substrate and whether the surface is stable and suitable for bonding. Taking time to prepare the installation properly can make a significant difference to the finished result.

GRP Adhesive & Sealant is designed to complement our range of anti-slip GRP products, providing a practical bonding option for installations where adhesive fixing is appropriate.

It can be used with several of our GRP safety products, helping create a clean and secure installation without changing the appearance or design of the GRP itself.

Anti-Slip GRP Flat Sheets

Our Anti-Slip GRP Flat Sheets provide a durable, high-grip surface that can be applied to larger flat areas. The adhesive can be used to bond the GRP sheet to suitable substrates such as metal, wood, concrete and brick.

Anti-Slip GRP Decking Strips

Anti-Slip GRP Decking Strips are designed to add additional grip to decking and other walking surfaces. GRP Adhesive & Sealant provides a bonding option for securing the strips to a suitable substrate.

Anti-Slip GRP Stair Nosing

Anti-Slip GRP Stair Nosing can be used to improve grip and provide a clearly defined edge to steps. The adhesive provides an option for bonding the nosing to a suitable stair surface.

Anti-Slip GRP Stair Treads

For worn, slippery or damaged steps, Anti-Slip GRP Stair Treads provide a high-grip GRP surface across the step. GRP Adhesive & Sealant can be used as a bonding solution where the substrate and installation requirements are suitable.

Good to Know

The adhesive is designed specifically to complement these anti-slip GRP products, but the most appropriate fixing method will depend on the GRP product, substrate and installation conditions.

From the Mats4U Team

If you're deciding between adhesive and mechanical fixing, don't automatically assume one method is best. Consider the condition and material of the substrate, how the GRP product will be used and the demands placed on the finished installation.

What is GRP Adhesive & Sealant used for?

Yes. Concrete is one of the substrates the product is designed to bond to, provided the surface is suitable and properly prepared.

Can it bond GRP to wood?

Yes. The product can be used to bond GRP to suitable wood surfaces. The substrate should be clean, sound and appropriately prepared before application.

Can it bond GRP to metal?

Yes. Metal is one of the listed compatible substrates. The condition and preparation of the metal surface should be considered before bonding.

Can it bond GRP to brick?

Yes. The product is designed to bond GRP to brick, provided the surface is suitable for adhesive application and properly prepared.

Can I use it on a painted or coated surface?

The supplied product information does not specifically confirm compatibility with every type of paint or coating. Existing coatings can affect adhesion, so the particular surface should be assessed and prepared appropriately before application.

Can adhesive replace mechanical fixings?

Not necessarily. Whether adhesive alone is suitable depends on the GRP product, substrate and demands of the installation. For some applications, mechanical fixing may be more appropriate or may be used alongside adhesive.

Is it suitable for every type of installation?

No adhesive should be assumed to be suitable for every application. The substrate, surface condition, GRP product and installation requirements should all be considered before choosing the fixing method.

How should surfaces be prepared?

Surfaces should be clean, sound and suitable for bonding. Dirt, grease, loose material, existing coatings and other contaminants can affect adhesion, so appropriate preparation is important.

Is the adhesive waterproof?

The supplied product information does not provide a specific waterproofing rating, so we would not recommend assuming that it is suitable as a waterproofing product.

Good to Know

Adhesive performance depends on more than the adhesive itself. The condition and preparation of the substrate, the GRP product being installed and the demands placed on the finished installation all need to be considered.

From the Mats4U Team

If you're unsure whether adhesive is the right fixing method for your particular GRP project, check the installation requirements before ordering. For more demanding applications, it can be worth considering whether additional mechanical fixing is appropriate.
