Frequently Asked Questions
What is included in the Caulking Range?
Products for a complete sealing job: joint preparation, primers, adhesives and sealants, dispensing guns, finishing tools, cleaners and thinners, and backing rod. Pick the part of the job you are doing, then check the individual product technical data for substrate, movement and cure requirements.
How do I choose a caulking product?
Start with the joint and substrate, then compare movement capability, internal or external exposure, cure chemistry, colour and pack format. Silicone, polyurethane, acrylic and hybrid MS polymer each suit different jobs. Confirm compatibility and application limits in the manufacturer technical data before you buy.
Do I need primer?
Some sealants go on without primer on common substrates. Porous, difficult or high-performance bonds may need a specified primer. Follow the sealant manufacturer's preparation instructions, not a general rule. Let the primer dry for the stated time before you apply the bead.
Why use backing rod?
Backing rod controls sealant depth, sets the correct joint profile and helps prevent three-sided adhesion. Choose open-cell, closed-cell or fire-rated product to suit the joint design. Install it without damaging the surface, then apply the compatible sealant over the prepared joint.
What tools do I need?
A complete job may need a cartridge or sausage gun, nozzle, scraper or spatula, finishing tool, masking materials and cleaning products. Tool choice depends on the pack format and bead profile you want. Keep uncured sealant off adjacent surfaces and follow the product's cleanup instructions.
