Creates a permanent waterproof barrier, for use with Marmox Thermoblock.  The only sealant available on the market that is completely VOC free.

Marmox Multibond is a premium sealant-adhesive.  It is made in the UK using the latest environmentally friendly technology to create a 100% solvent free material with absolutely zero VOC’s.

It is possibly the 'greenest' sealant-adhesive available having no hazardous, environmental or ecological impact.  Unlike other mastics, if it gets on your hands or even clothes it can be washed away with just water without leaving a mark.  Similarly it does not stain stone or ceramic tiling like conventional sealant-adhesives do.  Once Multibond sets it becomes incredibly strong and fully waterproof.

Being completely solvent free, it is compatible with virtually all materials.  Marmox Multibond is the all-in-one super solution that replaces all your tubes of silicone, acrylic and PU.  It also has acoustic properties so it not only bonds acoustic boards to the floor but also reduces the transmission of impact sound.

It is also ideal for sealing around shower trays and baths, around bathroom fittings, around kitchen fittings and furniture and also as a grab adhesive.  Because the material is made using a different technology to silicones, acrylics and MS-Polymers, there is no latent chemical process happening within the material that can cause it to discolour; Multibond cannot discolour - it will always stay brilliant white.
