Hot-pour Rubberised Sealant

Description
QUICSEAL 206 is a single component, thermoset, hot-poured sealant comprising of a homogenous mix of synthetic rubber, asphalt resin, chemical additive and fillers. The sealant is capable of retaining its elasticity and toughness over a wide range of service temperature. QUICSEAL 206 complies with BS 2499-1973 Type A2.

Uses
QUICSEAL 206 is an excellent sealant for horizontal application in :-
Road expansion joints
Concrete pavement joints
Flat roof joints / panel joints
Concrete bridges

Advantages
Elastomeric
Good adhesion and bonding strength to concrete surface
Good resistance to hot weather and sunlight
Easy to melt

Joint Preparation
Ensure that the joints are clean, dry and free from dust. Where old joints are being resealed, remove all old materials. Spalled joint should be made good.

Cement concrete joints: Prime joints sides with QUICSEAL 206 Penetrating Primer and allow to dry completely (approximately 30 minutes). Pour sealant on the same day, within 6 hours after priming.

Asphaltic concrete or mastic asphalt joints : Prime as above. Alternatively, carefully heat the faces of the joints with a propane burner until the bitumen binder starts to melt and pour the sealant immediately.

Application
Heat the sealant. Use only a melting kettle with an indirect heating system, such as hot oil heating.
Stir sealant continuously until thoroughly melted. Pour melted sealant (i) by hand from a can or (ii) by pressure fed heated hose, direct from melting kettle, through a special nozzle.

Temperature control is important. Do not allow oil temperature to exceed 240°C or the temperature of the molten sealant to exceed 180°C. QUICSEAL 206 will pour satisfactorily at temperatures of 145oC to 155°C.

Stir the contents of the kettle at frequent intervals during the melting process. Once melted, the sealant can be stored hot without stirring but should be used within 2 to 3 hours. Do not use material, which has gone cold and re-heated.

Allow the poured sealant to dry and settle for 4 – 5 hours before opening traffic.

Excess material can be removed when cold with chisel wetted to minimise sticking.
