SpECcord is used as a sealant back-up rod in
movement joints where cold applied sealants are
used, such as joints in or between:
· Concrete, blockwork and brickwork.
· Concrete, GRC and GRP precast panels.
· Metal cladding panels.
· Aluminium and concrete or blockwork structures.
· Aluminium members (non-structural glazing).
· Floor and roof joints (cold applied sealants).
· Door and window frames.
· Economical
· Non-hazardous
· Easy to install
· Excellent movement absorption
· Good chemical resistance.
· Acts as a bond breaker eliminating 3-way sealant
adhesion
· Not impaired by climatic extremes
· Provides minimum strain shape for sealants
Size Selection
The diameter of the cord should be about 25%
greater than the width of the joint so that the cord
fits tightly in, providing a firm support for the sealant
and ensuring correct sealant profile.
Installation
After selecting the correct size, push fit the cord into
the sealing slot using a blunt tool. Do not use any
sharp objects or tools that could puncture, cut and
damage the cord.
Watch Points
· If a primer needs to be used, apply the primer first
and wait for it to dry before installing the cord.
Solvents in the primer will damage the cord.
· After installation ensure that sufficient depth is
maintained for the sealant as recommended by the
sealant manufacturer.
· Do not cut the cord into halves or parts, as this will
affect its performance
