3 SURFACE PREPARATION:
The surface to be painted should checked for any rough imperfections which can be lightly sanded with 80 grit paper. Lightly abrade the entire surface to be painted to improve adhesion of the paint.

4 CLEANING
The inflatable tubes must be cleaned of dirt, oxidation & grease by using Polymarine Inflatable Boat Cleaner and then thoroughly rinsed and dried.

5 SOLVENT PRIMER CLEANER
When the entire surface is clean a final preparation of the surface is made with Polymarine P510 Hypalon Solvent Cleaner applied with a clean dry lint free cloth, paying particular attention to seam joints, nooks and crannies. The P510 will quickly dry and flash off ready for painting. (NOTE: 2681 Flexithane-Thinners  can also be used to clean and prime).

6 MASKING
Masking areas can be done by using standard Low Tack Masking Tape ensuring it’s firmly aligned at the leading edge. When painting to the mask with a brush, don’t use a freshly loaded brush, wait until it’s semi depleted (less paint) and always paint along and away from the leading edge, not into it, to help avoid bleed under. If masking a freshly painted surface, ensure paint is ‘Firm Dry’ and tape is low tack masking.

7 APPLICATION
Shake the Paint Tin vigorously prior to application. Add the approximate amount of paint you intend to use in one session to a paint kettle or similar container. Stir the container of paint every few minutes.

BY BRUSH (recommended)
It is recommended that Flexithane be applied using a good Brush with Natural Bristles. Synthetic Bristles may dissolve due to the solvents present within Flexithane.

ROLLERS (not recommended)
Use of Gloss Paint Rollers is not recommended as they’re usually synthetic and prone to breaking down due to solvents, thus spoiling your final finish.

SPRAY PAINTING – Professional use only with appropriate breathing apparatus
Spraying can be done using the Polymarine Flexithane 2681 Thinners, at a mix ratio of 1 Base to a maximum of 15% Thinners. Two spray coats should be applied as a minimum. Refer to SDS for cautionary and safety procedures.

CUTTING IN
First, ‘cut in’ around edges of all seams, patches and up to the leading edge of masking tape.

FLAT AREAS
Then apply to flat areas in light, even strokes using low build for maximum flexibility (avoid thick coats).

SECOND COAT
A second coat is easiest to apply when at least ’Firm Dry’. Note; Apply the second coat with a full brush, do not over work otherwise the second coat will re-dissolve the first coat.

8 FLEXITHANE DRYING TIME
Flexithane becomes ‘Touch Dry’ after approximately 5 minutes at 20°C and ‘Hard Dry’ after 20 minutes. Once the paint surface becomes ‘Hard Dry’, the second coat can be applied. A ‘Full Dry Finish’ will be achieved after 24 hours drying time.

9 FINISH & PRESERVATION
IBS-Finish-Comp-72Once fully dried, the Flexithane painted surface will have a Satin Finish that is highly elastomeric with an extreme stretch ratio that will not crack or flake off. It is resistant to wear, scratching and abrasion and will last many seasons.

To help maintain the new finish and to further resist the effects of UV, a regular coat of Polymarine  ‘Inflatable Boat Finish’ is recommended to be applied each time you clean your inflatable.

  1. Hello Mike

    If your cover is made from Hypalon yes, however, it’s more likely you cover is made from PVC and Flexithane should not be used on PVC.

    Instead use Polymarine Superflex, which is ideally suited to painting PVC boat covers, dodgers etc

  2. I want to paint the rubber rub rail/strake on my RIB. It is mold stained and I can’t get it clean. Can I use this product for that application? Thanks in advance. John

  3. Hello John

    Yes the Polymarine Hypalon Paint is ideal for re finishing tired, dirty and sticky rubber components like your rubber rub rail strip.

  4. Hi, we have a Hypalon RIB that is in the water and used all summer long on a passenger vessel. We cannot pull the boat each time we are done, we just tow it behind the big boat. We paint the rigid hull with ePaint anti fouling paint, but would like to know if there is an anti fouling paint compatible with Flexithane that we could use on the lower portion of the tubes. Also, there is some stubborn growth residue in that region, what might be a good product to prep for painting the Flexithane so it adheres properly? Boat is going in the shop for work/paint in a week or two, would like to do this right. Thanks in advance for any advice.

  5. Hi Zach, Yes there is Polymarine’s SP54 Hypalon Antifoul, Fully flexible antifoul for use on Hypalon material. Can also be used on non-flexible surfaces such as GRP. Hull and tubes can be protected on your RiB with just one product. http://polymarineshop.com/sp54-hypalon-antifoul-blue.html
    In addition, to clean up a fouled or stained surface, Polymarine Dispel a GRP Stain Remover. Removes rust stains, organic stains, algae stains. http://polymarineshop.com/dispel.html

  6. Can flexithane be used to change the colour of my tubes – they are currently yellow and I was thinking of having them grey or blue

  7. Hi James, Yes Flexithane is ideal for blocking out your old colour with a tough durable finish. Flexithane’s coating properties are highly opaque and normally require only one coat for true colour rendition. A second coat will enhance the smooth satin appearance.

  8. Where can I get all your products (Polymarine Inflatable Boat Cleaner, Solvent Primer Cleaner and Flexithane) in one place?
    Is there a equiv. product to the Cleaner and Primer – in case I can’t get them?
    I’m in NE Florida, but any internet provider would do.

    Thanks

  9. Hi, I’m a restoring a hypalon RIB and have some areas where the inner threading has been exposed. Would an extra layer or two of Flexithane for hypalon be enough to re-enforce these areas?

  10. Hi Jeremy, the Flexithane would be excellent to restore the finish of your fabric, however, it would not re-enforce fabric that is worn through. In places that take a lot of wear, adding a protective wear patch of Hypalon Fabric will re-enforce and prevent wear through. Dinghy Fabric is sold in small rolls and by the Sq Mtr. Often a D ring Patch or similar accessory if suitable, is a good solution.

  11. We are looking to do some painting on inflatable bouncy houses, would this time of paint work on them?

  12. If you mean as a surface treatment to stop leaks, then no, however it would improve the look of your old Caribe. With regard to tiny pin holes and porous fabric, then Polymarine Sealflex would be ideal as it coats the internal surface of the Hypalon Fabric to seal up pin holes and porous surfaces.
