the construction requirement of PU820
The main points of construction:
Substrate surface requirements: Keep dry, clean and pollution-free.
Construction tools: cutting machine, blower, filling and sewing equipment,or glue gun, brush, the scraper knife.
The construction method
1.Construction joint cutting: using the cutting machine cut the construction joints according to design.Using the
blower,brush,scraper knife remove the dust inside the joints and keep fully dry;
2.Liner material laying:
Put superior polyethylene foam than the joints into the construction joints,the depth is according to the construction
Using the equipment:Put the sealant into the filling and sewing equipment and set the glue hose into bottom of the
joints and inject the sealant into the joints.
Filling glue after construction should be lower than the road surface,in Summer for 2-3mm,and in winter 1-2mm.
expansion due to construction joint will change with temperature, therefore, filling glue after construction should be
lower than the road surface, summer for 2-3 mm, 1-2 mm. The winter;
4.Curing time:about 6 hours in summer, 12 hours in winter.
Construction quality inspection
Appearance inspection:the sealant should be fully of the designed joints,no bubbles and space.or cut the bubble
and space and infuse new glue to modified the surface.
Don’t mix alcohol into the sealant,it will Lead to serious failure of the sealant.
The sealant should be used in shelf life.It’s better to use up in one day once the drum is open.Otherwise,keep
it sealed.Check the effectivity next time when use it,and clear up the cured glue nozzle.
The curing speed will be slow down in ill-ventilated or low humidity environment
