Jointing Compound

About Jointing Compound

Jointing compound is an essential construction material designed for two distinct applications: creating seamless finishes on plasterboard walls and ceilings indoors, and filling gaps between paving slabs and block paving outdoors. MyToolShed.co.uk stocks professional-grade jointing compounds from trusted brands including Everbuild and Tetrion, catering to both trade professionals and DIY enthusiasts tackling home improvement projects.

Indoor filling and jointing compounds are formulated to embed joint tape, fill screw heads, and create smooth, sandable surfaces ready for decoration. Outdoor paving jointing compounds are engineered to withstand British weather conditions, prevent weed growth, and accommodate natural ground movement whilst providing permeable drainage. Modern formulations offer all-weather application capabilities and rapid setting times, making them suitable for year-round use across the UK's varied climate.

Applications

Jointing compounds are used across various trades and projects:

• Plasterers and Drywall Installers: Taping and finishing plasterboard joints in new builds, extensions and renovations
• Decorators: Preparing walls and ceilings for painting by creating seamless, invisible joints
• Landscapers: Pointing patios, driveways, garden paths and block paving installations
• Builders and General Tradespeople: Internal finishing work and external paving projects
• Property Maintenance Professionals: Repairing cracked plasterboard joints and deteriorated paving pointing
• DIY Enthusiasts: Home improvement projects from room plastering to garden patio installation

Choosing The Right Jointing Compound

Selecting the appropriate jointing compound depends on your specific application:

Indoor vs Outdoor: Indoor compounds prioritise smooth finishing and sandability for plasterboard work, whilst outdoor paving compounds focus on weather resistance, flexibility and weed prevention. These are not interchangeable products.

Weather Conditions: All-weather formulations like Everbuild Sika Fastfix can be applied in damp conditions and temperatures down to 5°C, essential for outdoor work during autumn and winter months. Traditional compounds require dry conditions above 5°C.

Setting Time: Fast-setting compounds allow quicker project completion, with some ready for overcoating within hours. Slower-setting products provide more working time for larger areas and inexperienced users.

Permeability: For driveways and patios, permeable jointing compounds comply with sustainable drainage regulations whilst preventing weed growth and allowing natural water drainage.

Format: Ready-mixed compounds like Tetrion Easy On offer convenience and consistency for DIY users, whilst powder products are economical for professionals covering large areas regularly.

Frequently Asked Questions

Can I use the same jointing compound for plasterboard and paving?

No, these are completely different products. Indoor filling compounds are designed for smooth, sandable finishes on plasterboard, whilst outdoor paving compounds must withstand weather and ground movement. MyToolShed.co.uk stocks both types—always select the product appropriate for your application.

How long does patio jointing compound take to cure?

Initial setting occurs within 24 hours, but full curing takes 3-7 days depending on weather, joint depth and product type. Avoid heavy traffic during this period. All-weather compounds typically cure faster in suitable conditions, whilst cold or damp weather extends curing times.

Will jointing compound stop weeds growing between paving slabs?

Quality paving jointing compounds significantly reduce weed growth by completely filling gaps where seeds germinate. However, no product offers permanent 100% prevention. Proper preparation including weed membrane beneath paving and occasional maintenance provides the best long-term results.
