Application and Dosage

When sealing leaks, relieve the water pressure before application if possible. Whilst LS-X is setting, drain system if necessary. Apply LS-X direct form the tube and mould into shape using a spatula or knife previously dipped into soapy water to prevent adhesion or dragging. Replace cap immediately after use. Allow a minimum of 1 hour to set. Time required depends on thickness applied. Spraying with water speeds curing.

LS-X may be used as a jointing compound on hot and cold water services, including potable water, in place of traditional materials. Reinforcement is generally not required, but reinforcement fibre may be used on larger pipe sizes.

The use of reinforcement material is advisable for larger leaks and higher pressures.
