Joint Sealant
1.01
Where so indicated on the drawings, joints are to be sealed using a fuel resistant, pourable, elastomeric joint sealant. All joints must be prepared, and primed if required, in accordance with the manufacturer’s current technical data sheet.
1.02
Preparation
The joint surfaces should be accurately formed and must be thoroughly dry, clean and free from frost. Remove all laitance, curing compounds, form release agents, loose materials and any contaminating foreign matter from joint faces by grinding, grit blasting or wire brushing. The prepared sealing slot should be blown out with dry, oil-free compressed air.
In moving joints, the sealant must not be allowed to bond to the back face of the joint. Prevention of 3 sided adhesion, is achieved by installing either a polyethylene bond breaker tape, or placing / pressure fitting a closed cell, polyethylene backing rod or filler board into the joint to support the internal back of the sealant.
New concrete must be allowed to cure for a minimum of 28 days before sealant installation.
All materials used in conjunction with the new sealant system, shall be approved by the sealant manufacturer.
1.03
Primer
Prime the two concrete substrate joint sides only with a Primer 7 and allow the surfaces to become touch dry before sealing. The sealant must be applied within the time period of between 30 minutes to 2 hours after priming depending on the climatic conditions. After 2 hours has elapsed, any primed surfaces must be reprimed before applying the sealant, therefore avoid priming more work than can be sealed in a two hour period.

Sealant
3.01
The Sealant is to be a cold applied, pitch-free, two component, elastomeric sealant designed for horizontal joints in concrete paved areas. It is to be resistant to fuel, oil and hydraulic fluid spillage and retain accommodating cyclic movement throughout extremes of temperature conditions.
The sealant may be applied in joints up to a maximum of 30mm wide. All moving joints should be designed to an optimal width to depth ratio of 2:1, with a minimum joint size of 12mm sealant depth.
The sealant shall exhibit the following properties:
Movement accommodation factor: / +/- 25% (total 50%)Typical hardness: / 18 (+/- 5) / Shore A (ISO 868)
Chemical resistance: / (Refer to listed chemicals in current technical data sheet)
Service temperature: / To avoid unacceptably prolonged cure times, do not apply at temperatures below 5oC
