Antifoul below 5 deg C

What will happen if I use Tiger Xtra below 5 deg C? Will it just take longer to dry or will it fail?

Boat has to go back in Tuesday and temps all sub 5 between now and then.

It will take longer to dry but its solvent based so its just a question of the solvent evaporating... no curing involved AFAIK.

The risk in doing at at low temps is that condensation will occur on the surface ... esp if you breathe. Provided the surface is a couple of degrees above the dewpoint you'll be OK I think.

Warming the paint a little may help application but the constraint regarding dewpoint and condensation still applies.

I am in the same boat (!), launch date set and no sign of spring until well into April. The Hempel data sheet gives the same warning as VicS re dewpoint but adds that the paint temp should not be less than 15C. I'm setting up a sort of bain-marie with hot water. Good luck!

Just a thought - how important is the appearance of paint underneath the boat, as long as it stays put?

I should think I have ever antifouled when the ambient temp has been above 15C

Not at all. At least I have had no complaints from the fishes about how bad mine looks !

( I though I heard some mutterings the year I used up all the dregs of various makes and shades of blue, but i may have imagined it. I took no notice anyway!)

If there is condensation on the surface though it is difficult to get the paint on, never mind staying put!

That was the point of my question - will it stay put? Not concerned about appearance.

Starting with the AF at room temperature helps a lot. Another good approach is to stir in a slosh of thinners (#3) which makes the first coat go on much more easily. Adhesion will be fine provided that the surface is dry.
