Sealants, Tapes & Adhesives

How to Choose the Right Sealant, Adhesive, Foam or Tape

Choosing the right product depends on whether you need to seal, bond, fill, fix or reinforce. Rose Building Supplies stocks general sealants, specialist sealants, grab adhesives, expanding foam, scrim tape, adhesive tape and wood glue for a wide range of building and repair jobs.

The parent category currently includes dedicated sections for General Sealants, Grab Adhesive, Expanding Foam, Specialist Sealants, Scrim Tape, Adhesive Tape and Wood Glue.

Which Sealant Should You Use?

The best sealant depends on the materials being joined, whether the joint needs to remain flexible, whether the area is internal or external and whether the finished seal needs to be painted.

For general building work, always check the individual product specification for substrate compatibility, movement capability, curing requirements and whether the product is suitable for indoor or outdoor use.

Silicone Sealant vs Decorators Caulk

Silicone sealant is commonly used where a flexible and water-resistant seal is required, such as around sanitary fittings, kitchens, bathrooms, windows and certain external joints.

Decorators caulk is generally used for smaller internal gaps and cracks around skirting, architrave, door frames and similar finishing work.

Caulk is typically chosen where the finished joint will be painted, while silicone is usually selected where flexibility and moisture resistance are more important. Always check the individual product instructions before use.

What Is CT1 Used For?

CT1 is a multi-purpose sealant and adhesive designed for bonding and sealing a wide range of building materials.

It is often chosen where one product is needed for both bonding and sealing rather than using a traditional sealant or grab adhesive separately.

Check the specific CT1 product information for suitable substrates, environmental conditions and application requirements before use.

CT1 vs Grab Adhesive - What Is the Difference?

A grab adhesive is primarily designed to bond materials together, often where a strong initial hold is required.

CT1 combines adhesive and sealing properties, so it can be useful for applications where both bonding and a flexible seal are required.

The right choice depends on the materials, movement, moisture exposure and the type of joint. For straightforward fixing work, a dedicated grab adhesive may be the simpler option.

What Is BT1 Used For?

BT1 is a specialist sealant designed for sanitary and wet-area applications.

It is commonly considered for kitchens, bathrooms and other areas where moisture resistance and hygienic sealing are important.

Always check the current product specification for suitable substrates and application conditions before use.

What Is Expanding Foam Used For?

Expanding foam is used for filling gaps, cavities and irregular voids around building elements such as window and door frames, service penetrations and other suitable construction joints.

It expands after application, so it should be used carefully and in accordance with the manufacturer's instructions.

Expanding foam is not a substitute for every structural fixing or weatherproofing product, so check the intended use before applying it.

What Is Scrim Tape Used For?

Scrim tape is a reinforcing mesh tape used over plasterboard joints before jointing or plaster finishing.

It helps reinforce the joint between plasterboard sheets and reduces the risk of cracking along board edges.

RBS stocks Scrim Tape as a dedicated category within both the plasterboard and sealants/tapes ranges.

What Is Adhesive Tape Used For?

Adhesive tapes are used for a variety of building, protection, fixing and temporary holding tasks depending on the tape type.

Because tapes vary significantly in adhesive strength, backing material and moisture resistance, check that the selected product is suitable for the intended surface and environment.

Which Adhesive Is Best for Timber?

For timber-to-timber joints, a dedicated wood glue may be the best option where the product specification matches the intended use.

For fixing timber to another building material, a grab adhesive or multi-purpose construction adhesive may be more suitable.

The RBS range includes a dedicated Wood Glue category alongside general construction adhesives.

Which Adhesive Is Best for Skirting & Architrave?

A suitable grab adhesive is commonly used for fixing skirting boards, architrave and mouldings where adhesive fixing is appropriate.

Decorators caulk can then be used for suitable small finishing gaps around the fitted mouldings before decorating.

Always consider whether mechanical fixings are also required for the particular material and installation.

Which Products Are Paintable?

Paintability depends on the individual product.

Decorators caulk is commonly selected for joints that will be painted, while many traditional silicone sealants are not intended to be painted.

Some hybrid sealants and specialist adhesives may be paintable, but always check the manufacturer's specification rather than assuming this applies to every product.

Which Sealants Can Be Used Outside?

Outdoor suitability depends on the individual sealant.

External products may need to withstand rain, UV exposure, temperature changes and movement between materials. Specialist or hybrid sealants can be suitable for some external building applications, but the substrate and exposure conditions should always be checked first.

Which Product Should You Use Around Windows & Doors?

The correct product depends on whether you are sealing, filling or fixing.

• Expanding foam can be used for suitable gaps and voids around frames.
• Flexible sealant may be required around perimeter joints.
• Grab adhesive may be appropriate for selected trims or finishing components.
• Decorators caulk can be useful for suitable internal finishing gaps.

Always use products that are compatible with the frame material and the intended internal or external application.

Which Product Should You Use for Plasterboard Finishing?

For plasterboard joints, scrim tape is commonly used to reinforce the joint before plastering or jointing.

Decorators caulk may also be useful later for small finishing gaps around trims, skirting and other internal details, but it is not a replacement for proper plasterboard joint reinforcement.

Do You Need a Cartridge Gun?

Many sealants and adhesives supplied in rigid cartridges require a cartridge gun to apply the product evenly.

The gun pushes the product through the nozzle, allowing better control over bead size and placement.

Check the packaging format before ordering so you have the correct applicator available when you start the job.

How Should Sealants & Adhesives Be Stored?

Storage requirements vary by product, but cartridges, foams and adhesives should generally be kept in accordance with the manufacturer's instructions and protected from unsuitable temperatures or moisture.

Check expiry dates and storage conditions before using products that have been kept for an extended period.

Can One Adhesive Be Used on Every Material?

No. Even products described as multi-purpose have limits.

Always check the manufacturer's compatibility information for the materials being bonded, particularly with plastics, metals, natural stone, damp surfaces or areas exposed to heat or moisture.
