Frequently Asked Questions
Which sealant do I use in a shower?
A sanitary silicone. Adheseal S-100, Bostik 6S, Mapesil AC, Matt-Seal S250, Matt-Seal S350, Pasco 912 and SA Sanitary resist mould and stay flexible at the tiled joint. Do not use a generic silicone where a sanitary grade is specified.
What is the difference between a sealant and a sealer?
A sealant fills a joint or gap and cures in place. A sealer penetrates a porous surface to block water ingress without forming a film. Pick the sealant for the joint. Pick the sealer for the surface.
Can I use a polyurethane sealant for waterproofing joints?
Yes. Polyurethane sealants like Adheseal PU240, PU25FC, Sikaflex 11 FC Plus and Megaprene 40 are built for movement joints in waterproofed assemblies. They are flexible and weather-resistant. Use the sealant the joint design calls for.
What is the difference between a sealant and a membrane?
A membrane forms the waterproof barrier over a surface area. A sealant fills and seals a joint, edge or gap. The membrane handles the field. The sealant handles the joints and terminations. Both are part of a complete system.
Do I need a fire-rated sealant?
Only where the building code or fire-engineering spec requires a fire-rated joint. Most waterproofing joints do not need one. Sealants Australasia Sealproof is the stocked fire-rated option.
