NEW 'Soft' Over NEW 'Hard' Bottom Paint

[witzgall]

Hi all;

I screwed up buying paint. Silly me figured if one "Fiberglass Bottomkote was ablative, they all are. Not true. Fiberglass Bottomkote with Ingersol is hard, and Fiberglass Bottomkote with ACT is soft. We already applied the hard paint yesterday. Interlux says to sand the hard paint and then put on the ablative.

The questions are:
- Do we need to sand this as it was just applied yesterday -
- What is the performance of the soft over hard, if both are new. By the time the soft is gone - will the hard kick in and be active?

I did the same thing intentionally with trinidad red hard and jotun blue ablative. Don't remember sanding and the paint has held up well. Were on 3rd year now and if we keep moving the bottom stays clean. Some red is showing through in places and there hasn't been any significant difference in growth.

Ask the paint manufacturer for advice.

Paint manufacturers have told me in the past that you can put ablative paint over hard. No sanding. I have done it many times, although not with the two paints you are using. You only have to sand if you go hard over ablative. I would called interlux back and verify (with another person) that you must sand. I really doubt it.

Gretchen had called them, and they said no. I called back, and this guy said as long as it is within a few days, it would be fine. So the second paint goes on today!!!

Thanks all.
