Taking out botton paint

[fisabel]

Hi,

Recently I purchase a 20' Sceptre hull that have some heavy layers of old botton paint. I will like to try to remove this paint and keep the original color or paint it white.
I will like to receive some advice from fellow members that have experience with this task.

You help will be highly appreciated.

One of the worst jobs inn the world. When you say old paint then I have to assume that its the old "hard" type of paint and not the ablative type used a lot these days.

I have attaemted and been fairly succesful at removing :a lot" of paint but not all of it by , scraping, sandinding, using paint remover, etc. Sanding did the best job, but it is nasty. IYou need to wear old clothes, resperator ,painters hood, and safety glasses. Otherwise you will end up with blue bottom paint(or whatever color) up your nose. in your ears eyelids hair, and any other orifice that is not covered. Been there and done that. Take a wide paint scraper fiirst , attach it to a pole like a broomstick using hose clamps and scrape off the fairly loose paint thjat you can. A lot of the outer layer can be removed this way. After that its down and dirty. I am going to haul mine soon and willl do some my self but not a complete job. A lot of layers of paint can accumulate in 20 /25 years also and getting a clean gelcoat is not possible I dont believe.You will probably notice a blister or 2 and this would be a good time to repair it also.

For anyone with an inboard, I have invented a good way to clean your shaft (see pictures)with relative ease of barnacles, slime etc. Snce my shaft is 1 1/4 " diameter, [img]images/icons/grin.gif[/img] , I take a slightly larger steel punch, hole cutter , 1 3/8"-1 1/2 first and remove a little over hafy of the cutting edge of the punch. It should fit slightly over your shaft to provide the most surface area when scraping. then scrape the outer most area of the shaft using this method. I then attach the punch to a broom stick, section of old outrigger, etc and use this for the remaining 4/5/ft ofthe shaft. very effective and it saves a lot of cuts on the hands. I then go back with sandpaper , fairly coarse, hold it around the shaft , spinning the shaft as nessesary to make it nice and pretty- Im still working on better/easier ways to do the wheel, strt etc. Good luck-craig

I have found the safest and easiest way to strip multi coats of bottom paint is to use a product called peel-away1. Home Depot carries it. you either brush it on or use a hopper gun with an air compressor. a hopper gun is also used to shoot plaster ceilings. A barrier paper is put over the product and in 48 hours you scrape the paper off with all the coats of paint attached to it.its great and environmently safe. good luck, stan

Two seasons ago I used a product called Stripeez which is meant for stripping paint off of wood, but worked very well on my bottom, which appeared to have all original 18 seasons worth of paint still on it. It is a paste, so you apply it with a paint brush, let it sit for 10 minutes, then scrape with a putty knife and off the paint comes. The only problem with Stripeez is that sunlight reacts with it and will burn the gel coat, so you have to be very careful, especially around the water line. On the bottom it is shaded, so not a big issue. I found that it is better to use in cooler temperatures since it is pretty potent stuff, so for you Florida guys this may not be the way to go. I did mine in March when it was in the high 40's, then applied new paint when it warmed up a bit.

Scott did you use the marine strip eez? I will be doing mine in the spring(March most likely) The brand that I have been looking at also has some sort of paper cover you put on it, is this the same stuff you used. There's nothing like first hand knowledge.
