SealXtra PS
TWO COMPONENT ELASTOMERIC POLYSULPHIDE JOINT SEALANT
DESCRIPTION SealXtra PS is two part polysulphide sealant which cures to form a durable,
flexible, watertight bond with most building materials and capable ofaccomodating dynamic joint movements. SealXtra PS is very good chemical,fuel and mild alkali resistant sealant. It is available in two forms: Gun Grade(GG) and Pouring Grade (PG).
STANDARDS BS 4254, BS 6920 (Gun Grade) , A STM C661, ASTM C920, Type M, Class 25
USES Sealing movement joints in building and civil engineering structures(expansion & contraction joints) , construction joints, control and perimeter
joints in parking decks, plazas, high rise buildings and malls, driveways,factory & warehouse floors, fuel storage areas, basements, reservoirs,subways, etc.
ADVANTAGES Elastomeric, reduced stress on the bond line
Excellent adhesion to substrates Meets requirements of most international standards
Good ageing resistance, excellent chemical & weathering resistance
Can accomodate continuous and cyclic movement

JOINT PREPARATION Surfaces must be clean, dry and free of dust, grease or parting compound.Concrete surfaces must be dry and at least 3-4 weeks old. Previously sealed
joints should be removed by mechanical means and should be ensured thatthere are no trace of residue left over it. Proper closed cell backer rods arerecommended because of their superior support to sealant under trafficablesurface loadings. Generally the joint depth should be equal to or half of its
joint width (i. e W:D - 2:1 or 1:1 ). If the edges of joint are generally weak, werecommend to cut the joint edges at both sides & repair it with epoxy mortarto avoid joint breaking & debonding of sealant from joints in long run.
PRIMING SealXtra PS, two part trafficable grade sealant, requires primer for masonary,steel and most common building materials. Joints must be thoroughly drybefore applying primer and sealant. If sealant is to be applied to a materialwith specially treated surfaces or particularly unusual surface characteristics,Consult Conmix Ltd for primer recommendations.Generally SealXtra Primeris recommended. After applying primer, SealXtra PS can be applied after aminimum period of 10-20 minutes.

MIXING Add entire quantity of Part B to Part A (in case of Pouring Grade) and mix
thoroughly under slow speed using drill with paddle. Gun grade just needsmixing as both the components are arranged in layers in the same tin.
FINISHING The sealant should be applied in such a manner so as to ensure freedom
from air pockets and to obtain good contact with the joint faces. This will be
assisted by good tooling practices.
