Anti-Pick, Balustrade & Specialist Joints We Seal

When Specialist Commercial Sealants Are Required

Standard soft silicone picked out or damaged in high-traffic public buildings

01

In schools, stadiums, public washrooms and secure units, standard soft sanitary silicone is easily picked or damaged. High-shore anti-pick mastic cures to a tough, tamper-resistant finish.

Chlorine and chemical degradation in leisure, pool and spa areas

02

Constant immersion, chlorinated water and aggressive cleaning chemicals break down ordinary silicone. We install specialist chlorine- and chemical-resistant sealants.

Crystal-clear glass-to-glass and balustrade jointing

03

Frameless glass balustrades and glazed partitions require high-modulus structural or optically clear silicone applied without air bubbles or smearing.

How We Deliver Specialist Mastic Packages

01

Review NBS specification, drawings or room schedule

Send your specification clause, drawings or site photos so we can confirm the exact product system and issue a commercial quote.

02

Submit RAMS, COSHH & manufacturer datasheets

We provide full site-specific RAMS, COSHH assessments and product compliance datasheets prior to starting on site.

03

Remove failed material and prepare/prime substrates

Joints are stripped (on remedial works), cleaned, masked where required and primed in strict accordance with manufacturer instructions.

04

Apply specialist sealant and complete QA sign-off

Anti-pick, balustrade or chemical-resistant sealant is gunned and tooled neatly with plot/room QA records for handover.
