No More Nails not drying outdoors – why?

Used No More Nails to help repair an outside door with new wood. The door spends most of the day in the shade, and only gets sun around 2pm till 330pm. Any clues why it’s not drying? I’ve leant a board against it to protect it from rain. Should I protect it with something like plastic sheeting to build the temperature when the sun is on it – will that help?

Not sure of the compound of that stuff but is it very cold there at the moment? It could be affected by low temp. any clues on the tube?

What drying time does it specify on the pack? I thought it went off by drying of the solvent; if that’s the case then humidity and temperature will have an effect.

Damaged by frost?

cold, damp, humidity, damp in wood… lots of reasons. the wood glue i use plays up like that this time of year, pain in the bum really.

Tube says to use above 5deg C. Probably dropped to around 2deg C last night, but temps are currently 8deg C and perhaps warmer in the door’s position in the sunshine.

hairdrier??

Anything I can do to help it dry out and set?

Use some nails to hold the new wood in place while the glue dries.

take the door off in the morning and take it inside the house. carry out repair. place against wall over radiator. refit the door in the evening.

i have the same problem at the moment; trying to keep the workshop warm enough so that the glues and paints dry without crippling the energy bill.

scrape it out and put in this instead this

‘No more nails’ is now a brand name covering a lot of different adhesives – so whether the glue needs to set by drying out (i.e. whatever solvent is in the glue evaporating out) or needs to react/cure chemically with the substrait or the atmosphere its not really easy to say. Being their DIY line the manufacturers seem a bit coy about saying what the various adhesives actually are, whereas trade-marketed adhesives would have COSSH sheets telling you exactly what the glue actually is. So its difficult to suggest what to do.

Some versions of this kind of gap-filling adhesive are polyurethane based and are actually encouraged to set by the presence of moisture (some will even set underwater). Some glues, PVA in particular, don’t behave properly if the temperature gets too low before they’ve set and if they’re cold-effected then the glue is goosed it just sets all brittle and powdery. I try to do any gluing at this time of year with polyurethane (such as gorilla glue) as the conditions actually favour the glue curing.

Get it warm. May be too late but I have done near instant fixes with the stuff and a hot air gun. A repair to a Landrover bulkhead took 5 minutes and has lasted over 5 years so far.

Take it off and go to the boat chandlery to get some Sikaflex 291i.

I use this all the time its amazing!
