Answer

I would recommend two coats. Also, make sure that the bottom is properly prepared to receive paint. I have not had much luck with the no-sand primer.

Answered on 10/05/2015 by JIM MOSS

Answer

Two coats is great. And of you have any left over after that, I would recommend you hir the bow again.

Answered on 10/05/2015 by LONNIE WEMPNER

Answer

This is the best paint I ever used and I will never try others (hands down the best, been there and done that with other brands). I have been bottoming my boats for 11 years now and I always used 1 solid coat only and never had an issue. That's assuming the bottom already had paint on it at some point. If it has no paint then you want to dewax, roll primer then antifoul paint it. Good luck and have fun. PS Properly taping off with painters tape is key and could take just as long as it does to paint the boat.

Question

Is this applied directly to the fiberglass or is there a need for an epoxy base first?

Asked on 04/26/2013 by Robert G

Top Answer

After scraping off about twenty years of old paint, I applied the ACT bottom paint directly onto the fiberglass. I keep the boat in brackish water off of Great Bay in southern New Jersey and when we hauled the boat out for the winter, I was amazed to see virtually no barnacles or slime on the boat.

This may be applied directly to fiberglass, it may require multiple coats.

Answered on 05/16/2013 by TOM SALEY

Answer

Yes you can. The following comes from the directions: BARE FIBERGLASS - (POLYESTER OR VINYLESTER) Clean with Fiberglass Surface Prep YMA601. Remove sanding residue. Remove mold release wax using one of the following methods. Low VOC System Apply Fiberglass Surface Prep YMA601 with a maroon, 3M ¥Ë_¥Ë_¥Ë_ Scotch - Brite’¢?¥Ë_ pad and scrub well. Flush with fresh water or wipe off with a clean, wet cloth ensuring that no traces of Fiberglass Surface Prep remain. Solvent System Dampen a cheesecloth with Interlux Fiberglass Solvent Wash 202. Wipe thoroughly to remove all surface contamination and cleaners. Wipe off with a clean, dry rag before liquid dries. Wipe only a few square feet at a time and change rags frequently. Finally To be certain the contamination has been removed, run water over the surface. If the water beads up or separates, repeat one of the above methods. When the water sheets off, all contamination has be removed.

Answer

I am not an expert, but I do know that for bare fiberglass, wipe it down with straight acetone before applying any type of paint.

Answered on 05/17/2013 by JOSEPH MULLER

Answer

I am not an expert on this.. but Jamestown people should be able to answer your question. On new fiberglas I am sure you would have to sand the bottom to take off the shine so the paint (actually any paint) would adhere. Can not imagine you would need anything else but the Act Paint.

Question

I put coat of ACT in March. Still looks good - no growth!! How long should the ACT last - do I need to put fresh coat on before each season? The boat will be out of the water from December thru April? John

Asked on 09/19/2011 by John Fewer

Top Answer

Hi John, My boat is in saltwater for about 7 months out of the year, and when I pull it out, the bottom looks very good. I think the reason for this is because I give it a light sanding before I put 2 coats on. I was told that if you paint the bottom, you need to put the boat in within 4 weeks or you will need to lightly sand it again,to activate the paint. I do paint it before each season. mike

John: I put on two coats, winter in the water north of Boston and get two years before the need to re-coat. I have a lower-speed planning hull (cruise at 12-16 knots). What builds up between usage typically comes right off when underway. Gene

Answered on 09/20/2011 by JWHEATON ENTERPRISES

Answer

I have been using ACT for the last 7 years with good results, no growth or barnicles. After painting the bottom of the whole boat, i only touch up any bare spots the following years. I rarely paint the bottom of the whole boat. This prevents buildup of paint that will evenually need removal. Just my opinion. Ron

Answer

I put a coat on in the spring of 2010. It looked good in the spring of 2011 and I put her back in. I have noticed my base color coming through in mid summer. I have not had any growth, but I will begin to add a coat every year.

Answer

Yes, it's a very effective antifouling paint but has been discontinued since Irgarol can no longer be produced.

Answered on 12/06/2015 by KEN HAYES

Answer

It will work just fine as long as the surface is prepared properly. The bottom on our 44 foot houseboat is fiberglass and it was sand blasted and then wiped with acetone. 5 layers of Inner Protect was then applied and then the Act was applied. Our boat stays in the Mississippi year round and is hauled every fourth year for bottom work. This will be our thirteenth year and the bottom is still looking good. The work and expense is worth it in the long run.

Answered on 04/26/2015 by JAMES WILSON

Answer

You asked -- how long between painting and launching with Iterlux ACT bottom paint? From Interlux they advertise "paint in the Fall and launch in the Spring." I've never delayed this long but have painted and launched 6-weeks later when an unexpected delay happened right before launch; good results for me with 3-days to 6-week delays in a Chesapeake Bay environment. Good luck.

I'm purchasing a 27' sailboat, that will be slipped in a freshwater lake in TX. How often does this need to pulled out of the water for a new bottom job? I'm trying to find a good quality paint that will last the longest.

Asked on 04/14/2015 by E C

Top Answer

Although I cannot predict how this product will perform in fresh water, I have had good success in salt water in Plymouth MA. At seasons end (November) I power-wash the thin layer of slime and lay the boat up for winter. Come spring I wipe the bottom with a large sponge and liberal amounts of water and apply a new coat of ACT or until the gallon runs out. My bottom was initially stripped and prepped with 3 coats of barrier coat so that when the bottom paint is thin the barrier coat is exposed. I have a 30' Pearson 303.

Answer

Well, I'm at the complete opposite end of you. I have a 27' power boat up in MN. I have found over the past 7 years that I have used ACT, that it's best to give the bottom a sanding every spring, and follow-up with one coat one year and then 2 coats the next. I will say that it works fantastic. My waterline is always clean.

Answered on 04/14/2015 by LONNIE WEMPNER

Answer

Thanks so much for the help on this. Most of the lakes around with the 27 foot sailboat will need a crane to bring it out of the water which is a big expense. This is why I'm asking so if I can get 2 years before I need to bring it out for a redo this would be better.

Answered on 04/14/2015 by E C

Answer

My 26 foot cabin cruiser is moored in a freshwater lake in PA from end of April to end of September. It is stored on its trailer during winter months. I examine boat bottom each fall and have repainted bottom every other year mainly due to on and off trailering. I have found the Act Interlux with slime fighter protects boat bottom very well. Boat sits through week and is used on weekends. Any slime forming through week is eliminated during weekend use. Recommend paint highly!

Question

I plan to use Interlux ACT on my 22' Ebbtide How much do I need for one coat?

Asked on 05/14/2012 by Pete P

Top Answer

I'm sorry, it's been too long since I bottom-coated my Mongomery 15, and in any event, I applied multiple coats, since this was the initial bottom paint on this lapstrake molded hull (had to paint because of gelcoat repairs) and I wanted a fairly heavy coating. I do believe that I went through about 1-1/2 gallons. Because this is an ablative paint, you may well wish to purchase "more than you need," so that you'll have extra to touch up the hull as the paint wears (or, perhaps, is scraped by, say, boat trailer bunks or hoisting straps.)

Hi Pete, I have a 23' walk around deep vee proline and 1 gal. will be enough for one coat but they recommend 2 coats. I do manage to squeeze out 2 coats out of 1 gal. and had no problems at all at the end of the season when I pull it out. mg

Answered on 06/08/2012 by MICHAEL GOODENOUGH

Answer

Pete you should be safe with 1 gallon, however I would view interlux's website. You should take into account the bottom paint and condition of the bottom of your boat. 1 gallon will do the bottom of my 27 foot wellcraft . regards Nick

Answered on 06/07/2012 by NICHOLAS FELIX

Answer

One coat on a 22 foot Ebbtide is going to require about 2 quarts (plus or minus). One gallon will provide you enough for two, nice, even coats.

I have a Post 47 that I keep on the St.Croix River in Minnesota. I applied ACT with Slime Fighter three seasons ago and have yet to have to re-apply another coat except for the waterline and front keel due to beaching the boat. With little effort and a pressure washer the seasons slime comes right off. Please keep in mind our season is only six months long and the boat is pulled for winter storage. The product is great and everyone that I have recommended it to agrees. Good boating!
