Interlux Bilgekote

Interlux Bilgekote is a fast-drying, durable coating formulated for application to bilge areas. Painting your boat's bilge helps prevent absorption of oil, gasoline or sludge into wood and fiberglass.

Bilgekote protects bilges, lockers, and bulkheads against moisture penetration and wear and tear. Bilgekote is easy to clean while providing excellent resistance to oil and fuel spillage.

Ventilation and Humidity Control It is best to paint on warm, dry mornings. Cold weather retards the drying and humidity can spoil the gloss.

Airless Spray Pressure: 170 bar/2500 psi. Tip Size: 0.33-0.41 mm/13-16 thou.

Conventional Spray Pressure Pot: Pressure: 3.44-4.47 bar/50-65 psi (gun pressure); 8-10 psi (pot pressure). Tip Size: 0.89-1.4 mm/35-50 thou. Siphon Cup: Pressure: 3.44-4.47 bar/50-65 psi - gun pressure. Tip Size: 1.5-1.8 mm/60-70 thou.

Other Spray pressures listed are recommendations only. The applicator may use any settings which yield the best results for the individual spraying technique and current weather conditions. Bilgekote is best applied in thin coats.

Some Important Points Do not apply heavy coats as this will affect dry through. Failure to follow proper dry times carefully will cause improper drying, wrinkling and loss of adhesion. Product temperature should be minimum 10 deg C/50 deg F and maximum 29 deg C/85 deg F. Ambient temperature should be minimum 10 deg C/50 deg F and maximum 35 deg C/95 deg F. Substrate temperature should be minimum 10 deg C/50 deg F and maximum 29 deg C/85 deg F.

Compatibility/Substrates Surface must be dry and clean, and free from grease, detaching paint etc. Be sure to use Epoxy Barrier-Kote 404/414 over clear epoxy to prevent blush from affecting drying and adhesion of Bilgekote.

Works great with my entire fleet!


After using this product on a new wooden boat in my rental boat fleet we were so impressed with its outcome we decided to paint our entire fleet's bilges. The end result will be less painting for us next year AND a better seal on the worn wooden floors of our boats. It even sealed and coated previously painted areas very well. The boats look great and are better able to stand up to daily summer use.

A really superior paint!


Very good paint with a nice result. Use a roller for best results and use a chip brush to get into tight corners.

Good Stuff


Works well in two coats. Dries to a Hard Gloss shine and offers a durable hard as nails finish.

Kiwigrip non-skid


Used kiwigrip as non-skid on the swimstep and it came out great. Very happy with the product and its ease of use. I scrubbed and pressure washed the old non-skid (which was LP/sand) and rolled the kiwigrip over the top. No problems with adhesion and it looks like new.

Interlux Bilgekote


Used Bilgekote on the interior of my 1970 oday rhodes 19. Over the last 5 years I have I have recoated ir three times. Each time I only put one coat on. It needs multiple coats for coverage but it has held up well and is easy to clean with a sponge. I think this is a great product and will last for a very long time.

interlux bilgekote

roll & tip


Bill asks about roll & tip. To me this is roll it on and follow up with a small brush on hte ridges,runs, etc, if any.

This is a great product for your bilge.


I have a 1970 Rhodes 19 I have completely restored, about four years ago. I used Interlux Bilgekote on the complete interior. First cleaned bilge very well with soap and water. Scraped and sanded any old paint and loose fiberglass for a smooth surface. cleaned again with soap and water. With a brush and roller put on two coats.After four years I just cleaned it well again and put one coat on. This has been easy to maintain and keep clean. The bilge is wet all the time and for the most part all I have to do is rinse it down wipe it dry to keep it looking great.

No long term reliability


I used this paint for the cockpit in my late 60s Oday Daysailer I. Since its an open cockpit single wall boat, the cockpit is also the bilge so I wanted a hard wearing paint that could take the water and the abuse. I don't have any long term reliability, ie just painted a few days ago I can say this: This paint goes on easy with a roller and looks great. Dries quickly and with 3 coats it has left a hard glossy finish I'm really happy with. Preparation is everything, so make sure to sand and prep the surface accordingly. And either spring for the Brushing Liquid 333 or make your own at home (Protip: MSDS sheets list ingredients)
