Leak Sealant

Stage 1 of the Sylmasta Pipe Repair System

Sylmasta Leak Sealant products repair holes and cracks in burst and leaking pipes, forming the first stage of the Sylmasta Pipe Repair System.

Repairs made using Leak Sealants are effective on pipes of all diameters made from steel, copper, plastics, malleable iron, GRP, ceramic, clay, concrete, rubber, and lead.

Where pressure cannot be turned off, Wrap & Seal Pipe Burst Tape is wrapped around pipework, fusing into a silicone rubber band which seals live leaks.

When flow can be isolated, Superfast Epoxy Putty plugs smaller holes and cracks quickly and easily. To improve effectiveness, specific formulations of Superfast are manufactured for different pipe types.

For larger repairs where a greater quantity of putty and a longer work time are required, Sylmasta AB Original offers a two hour cure time. AB Original comes with high chemical resistance, extreme temperature resistance and bonds well to wet surfaces for underwater repairs.

Sylmasta AB Rapid 5 Minute is a quicker working version of Sylmasta AB; offering the bulk quantities of AB Original and the speed of Superfast Epoxy Putty.

Wrap & Seal, Superfast Steel and Superfast Copper all have WRAS approval, meaning they are certified to British standards as safe to use on pipes carrying drinking water.
