Bottom Paint in Fall

[Bill Balme]

Is there any problem putting on antifouling in the Fall and letting the boat sit on the hard until the Spring?
Someone told me the paint shouldn't be allowed to completely dry out???
(Planning on using Micron 66 probably)

Some of the manufacturers have long launch times for their paint but that is a long time, you need:

Boatpaint.co.uk Shop

I buy the paint in the fall when the chandlers are selling off old stock and apply end of april or early May so that the maximum strength co-insides with the worst fouling season - May - Sep for us.

Just can't be doing with trying to paint a boat in February, too cold.

Bill , sorry the product data sheets seems to have disappeared from that website which would have given you the maximum times before launching.

However, it does say that Micron 66 has been replaced with 77. If you have a choice I would be reading the contents of both types to see if they have reduced the quantity of something that could be important.

I used Micron 66 and was advised after a layup for several months to give the paint a light powerwash before re-launching. Apparently the surface oxidation or whatever's acquired when on the stands needs to be knocked off so the paint can resume ablating once in the water.

FYI- ablative paints (like the OP's Micron 66) can withstand prolonged exposure to the air. Hard paints (like Pettit Trinidad etc.) cannot.

Interlux says: Max time after painting and before immersion is 1 month in tropical conditions and 3 months in temperate. If left longer, fresh water
pressure wash is required before immersion.
