Fix & Seal High Tack

SP350 has been developed to bond materials to floor, wall and ceiling, where the extremely high initial strength of the product is very useful for this high performance adhesive.


SP350 is ideal for a vast range of interior & exterior applications and may be applied to damp substrates. Applications include:

  • Fixing Aluminium and PVCu nosings and extrusions to concrete and wooden stairs. 
  • Carpet grippers to most sub floors without using tacks or nails. 
  • Most types of wall cladding, direct wall studding, internal wall surfaces or timber battens.
  • High initial grab and rapid development of final bond
  • Formulation is solvent free, very low odour, and chemically neutral
  • Instant grab can minimise the need for additional clamping or other mechanical supports
  • Good resistance to light, weather and ageing - suitable for internal and external applications

Usage Guidelines

  • May be applied to damp substrates. 
  • For optimum adhesion, surfaces should be clean, dry, sound and free of contamination.
  • Always carry out a test to confirm compatibility prior to use.
  • Roughen non-porous surfaces.
  • On materials such as glass, aluminium, ceramics, lacquered wood, epoxy and polyester no primer is required. For other materials, please contact tremco illbruck Technical Services.


SP350 is a one component, non-sagging, elastic adhesive based on hybrid polymers.
