Gap Filling Adhesives

About Gap Filling Adhesives

Gap filling adhesives are high-performance bonding solutions designed to join materials whilst simultaneously bridging uneven surfaces and voids up to 25mm or more. Unlike standard adhesives requiring tight surface contact, these versatile formulations contain fillers that make them ideal for fitting skirting boards, architraves, coving, plasterboard, and panelling where traditional fixings prove impractical. MyToolShed.co.uk stocks trusted brands including Everbuild, Evo-Stik, and Sealey, offering both solvent-based and solvent-free options to suit different working environments.

Modern gap filling adhesives like Everbuild PinkGrip and Evo-Stik Gripfill combine powerful initial grab strength with excellent gap-bridging properties, often eliminating the need for mechanical fixings and significantly reducing installation times. Available in cartridges for skeleton gun application or hand-applied tubes, these products work across timber, plasterboard, concrete, metal, and plastics, accommodating natural material expansion and contraction whilst maintaining bond integrity.

Applications

Gap filling adhesives serve numerous trades and applications:

• Joiners and Carpenters - Installing skirting boards, architraves, dado rails, and decorative mouldings without visible pin holes
• Dry Liners - Bonding plasterboard, insulation boards, and coving to uneven walls and ceilings
• Kitchen and Bathroom Fitters - Securing plinths, end panels, splashbacks, and worktop upstands
• Shop Fitters - Rapid installation of display units, wall panels, and retail fixtures
• Builders and General Contractors - Window board installation, temporary and permanent fixings across diverse projects
• Facilities Maintenance Teams - Quick repairs and installations in commercial and industrial settings
• DIY Enthusiasts - Home improvements and renovation projects requiring professional-quality results

Choosing The Right Gap Filling Adhesives

Working Environment: Consider ventilation and occupancy. Solvent-free formulations like Everbuild PinkGrip Solvent Free suit occupied spaces, whilst traditional solvent-based products offer faster initial grab in well-ventilated areas.

Substrate Materials: Universal adhesives like Everbuild Stixall bond virtually all materials including metals and plastics, whilst standard grab adhesives excel with porous materials like timber and plasterboard. MS polymer options provide superior flexibility and weather resistance.

Gap Size and Load: Standard formulations typically bridge gaps up to 15mm, whilst heavy-duty products manage 25mm or more. Match the adhesive strength to the weight and structural requirements of your application.

Cure Requirements: High-grab products like Everbuild Instant Nails allow immediate positioning without props. For applications where clamping is possible, standard cure times offer economical performance.

Finishing: Choose overpaintable formulations if the adhesive will be visible. MyToolShed.co.uk stocks products in various colours, including PinkGrip's distinctive pink for precise application visibility.

Safety Information

Ensure adequate ventilation when using gap filling adhesives, particularly with solvent-based formulations. Wear appropriate gloves to prevent skin contact and potential sensitisation, and use safety glasses when working overhead. Store cartridges in cool, dry locations away from heat sources and direct sunlight. Solvent-based adhesives are flammable—keep away from naked flames and sparks. Dispose of empty cartridges according to local authority guidelines, as many contain residual materials requiring proper waste handling.

Frequently Asked Questions

Can gap filling adhesive replace mechanical fixings?
In many applications, yes—modern formulations provide sufficient bond strength for skirting, architrave, and panelling. However, for structural applications, heavy loads, or safety-critical installations, always follow building regulations which may require mechanical fixings.

How long before I can paint over gap filling adhesive?
Most paintable gap filling adhesives can be overcoated within 24 hours, though some rapid-cure formulations allow earlier decoration. Always check the manufacturer's technical data sheet and ensure the adhesive has fully skinned over before painting.

What's the shelf life of adhesive cartridges?
Unopened cartridges typically last 12-18 months when stored correctly. Once opened, most products remain usable for several weeks if the nozzle is properly sealed between uses.
