Marmox Multibond

Having recently used this in our bathroom, can the panel suggest any reason why Marmox Multibond:

couldn't be used in place of Sikaflex/PU40/etc. on board? It seems to have better eco credentials...

Thanks!

Dont know the stuff but since it can be washed off with water before it sets that suggests it cant be used on damp surfaces which is one of the real pluses for PU40/CT1 etc.

The blurb says "Marmox Multibond replaces all your tubes of butyl, acrylic and silicone" but doesn't mention PU based sealants (presumably polyurethane). They give a number in their description, maybe you should give them a ring to establish its suitability.
Personally I'd use PU40 from Toolstation - it's cheap and performs well as a sealant adhesive.

Thanks very much for the replies. PU40 purchased!

I've not tried IPT sealants yet, but the 15% shrinkage would limit its usefulness aboard. Also, the data sheet mentions it's available only in white. It is paintable, but not sandable, which is another downside. I think currently a tube of MS Polymer is probably the most versatile to carry, and PU sealants are still good for niche uses (below waterline/away from UV).

Generally I've found sealants of the same chemistry fairly interchangeable between brands, i.e. most PU sealants act the same with minor differences (biased more towards adhesive or sealant), and the MS Polymer ones I've tried are pretty much the same no matter what brand is printed on the tube. Our last one was branded Fratelli Zucchini ("Zucchini Brothers") bought in a Sicilian chandlery and actually very good quality for just €8 a tube.
