How do you get barnacles off a boat bottom?

Question

Just the shell base remain. The boat has been scraped

Answer 1

Get a garden sprayer, get Hydrochloric Acid its available through any chemical company... spray it down let it stand for about 10 min pressure wash them away.. The WORKS TOILET BOWL Cleaner is easier to obtain and does the job, its not as concentrated form but it will work... some times if they are really stubborn I very carefully use a wallpaper scraper ..... I hope this helps you... Good Luck

Answer 2

They need to be scraped off. Use a chisel carefully. Barnacles can make nasty cuts which are easily infected. Sand off.Sand blast. Sounds like the boat was high pressure washed and not scraped. Do you have blisters?

Answer 3

I had the same problem years ago. What I did was trailer my boat to a "Freshwater" lake and spent the day wake boarding and waterskiing. That removed the barnacles and calcium pad from the hull. the friction of the water did the work. If you have a lot of deep build up, you'll need to maybe spend two days on freshwater to remove it all.

Answer 4

Round here they use an industrial pressure washer, much higher pressure than the car wash type and they blow everything right off the hull without destroying the gel coat or paint.

Answer 5

Just use a good bottom paint, and paint right over those barnicle bases

Answer 6

a sander or sand blast it. if nothing else call boat dealer or marina where they repair boats.

Answer 7

depending on what type of bottom...u can either use zing and elbow grease or combination of zing then boat wash w/ elbow grease

Answer 8

scrape it with a scraper
