Why use an internal tank coating
A problem fuel tank should be replaced with a new one, but as often the case they are usually unobtainable one solution is to have this professionally repaired by welding new metal into the structure or as a last resort treating and coating the inside to form a strong inner lining to protect from rust deposits and help seal any leaking joints or corroded areas.
Description
FLOWLINER is a two pack solvent free epoxy petrol tank coating, which when cured will form an extra strong lining inside the fuel tank.
Preparation
Prepare the fuel tank by removing any fuel taps, sensors, filters etc. all exits & threads must be protected & sealed to prevent any leakage, seal with either a blanking plate, cork or wooden dowel, internal threads can be sealed with a smaller diameter bolt with masking tape wrapped around the thread, then grease the blanking bolt & screw into the inside of the petrol tank to a depth of about 3mm.
The fuel tank must be thoroughly clean making sure that all traces of stale fuel and oil have been removed, then if rusty, treat with a rust remover such as FLOWLINER BIO-RUST a biodegradable safe method of treating rusty components.
Mix the FLOWLINER BIO-RUST @ a ratio of up to 20 parts of hot water to 1 part of FLOWLINER BIO-RUST, as a guide a one kilogram unit of FLOWLINER BIO-RUST will treat up to a 20 to 30 litre tank, when the tank is full leave for 12 to 24 hours do not leave the tank sealed up. Drain the fluid into a plastic container; this can now be used as a dipping solution for any other rusty items.
If some rust is evident in the tank this can be easily removed by agitating the tank with some sharp gravel, sand, lengths of small chains or nuts & bolts in a litre of FLOWLINER BIO-RUST, then wash the tank thoroughly with a mild hot detergent wash and then rinse thoroughly and leave to dry.
We advise rinsing the tank with a miscible cleaner such as FLOWLINER SOLWASH. This is miscible with water & helps dry the moisture from the tank. All areas must be free of moisture. Any contamination or moisture will inhibit the coating process. Pour the FLOWLINER SOLWASH into the dry tank and agitate to remove any contamination.
The fuel tank must be free of any deposits which may inhibit correct adhesion.
On new and smooth bare metal fuel tanks we advise a coating of acid etch primer to help with adhesion.
Mixing
Store the FLOWLINER at room temperature for 24 hours before using.
In very cold conditions the white product in tin 'A' may look to be solid but can be reconstituted by slackening the lid and carefully standing it in warm water for 30 minutes, it must be left to go cold before using. Pour the contents of both tins into a clean container and mix the FLOWLINER together for five minutes.
Application
Pour the FLOWLINER into your prepared tank, seal the filler neck and invert, now move your tank slowly backwards and forwards, side to side until you are sure that all the top of your tank is coated, now stand your tank on one end and wait 2 minutes until the rest of the FLOWLINER has collected, now coat the rest of the tank as previously, checking inside to see if you have coated the tank completely, now stand your tank on its other end and allow the product to collect, repeat the process again, remember the more times you repeat the process the thicker the FLOWLINER coating will be, the final coating should be as the product has thickened due to the curing process, you need to turn the tank to enable the thick product to drag over the surfaces leaving a even coating of around 2m.m. anything less than the recommended thickness may fail especially with the recent addition of ethanol to fuels. On severely corroded petrol tanks a second coating may be required. Gelling times will vary with temperature but will be around 2 to 3 hours, touch dry in 12 hours, fully cured in 7 days at room temperature. Do not leave the tank sealed up when curing.
DO NOT FILL WITH PETROL UNTIL FULLY CURED.
All work and fuel testing should be carried out prior to refinishing the exterior of the fuel tank, as all parameters for the coating are out of our control any liabilities lie with the user.
