Hi I have been trying to put up a bew wall cupboard in my utility room. Tried fixing into thermalite block but it crumbled away no matter what did. So as a last resort I used screwfixes own easyfix-kem-psc-175-ef-chemical-resin-175ml (5650j) this worked well and the cupboard is now in place but the smell doesn't go away, it's been two days now and It's still horrendous. does anyone have any experience of using this product and how long the smell may last, as I'm sure my wife won't put up with me leaving the windows and doors open much longer :-( Many thanks
