Superflex flexible PVC Paint User Guide

The use and application of Flexible Paint to PVC Dinghies, RIBs and Inflatable Boats,

superflex-flexible-pvc-paint-coPolymarine have formulated a specialist PVC paint called Superflex for the renovation of inflatable boats made from PVC and any other PVC variant material.

Superflex adheres in a super strong flexible bond, becoming part of the surface withstanding weathering, abrasions and retaining colours and bright whites for many years. It has a super high stretch ratio that will not crack or flake off. Superflex’s coating properties are highly opaque, easy to apply and quick drying. Application is one coat for good surface adhesion and a second coat for a smooth satin appearance and improved, lasting durability to UV and the elements.product

Before preparing and painting please note:- your workplace needs to be well ventilated, dry and comfortably warm ideally 10 to 20°C. Damp and High humidity may cause blooming. Do not use a gas fire or naked flame heat source as the paints and solvents are highly flammable.

2 to 3 square metres per 500ml Tin of Polymarine Superflex. One Tin will cover up to 10 square metres in one coat. For best results apply two coats which gives an average coverage of 2 to 3 square metres depending on surface condition and application.

It is recommended to repair and reattach components or patches that may be coming lose prior to painting. Use a hot air gun to soften old glue. Wipe away with 2903 solvent.

The surface to be painted should checked for any rough imperfections which can remedied and cleaned.

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

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: 2661 Superflex-Thinners can also be used to clean and prime).

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.

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 Superflex be applied using a good Brush with Natural Bristles. Synthetic Bristles may dissolve due to the solvents present within Superflex.

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 Superflex 2661 Thinners, at a mix ratio of 1 Base to a maximum of 30% Thinners. Two spray coats should be applied as a minimum.  Refer to SDS for cautionary and safety procedures.

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

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

This 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.

Superflex becomes ‘Touch Dry’ after approximately 5 to 15 minutes at 20°C and ‘Firm Dry’ after 1 Hour minimum. Once the paint surface becomes ‘Firm Dry’, the second coat can be applied. A ‘Full Dry Finish’ will be achieved after 24 hours drying time.

Once fully dried, the Superflex 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. Superflex does stand up very well to abrasion but in effect it would not be a lasting solution to heavy abrasion due to being scraped on a concrete slipway. If in your circumstance there is a particular unavoidable wear point, then a suitably shaped PVC fabric patch would be recommended as a sacrificial surface. Various colours and sizes are available here

  2. Hi

    I got an inflatable dinghy last year (Kilobri KM300) which I understand is made from PVC. I am looking to protect the underside of the PVC floor from nicks and scratches when the dinghy gets beached on a beach or slipway. As you may be aware these floors don’t put up with much wear and tear…!!

    Will the above product (Superflex flexible PVC Paint) be suitable or would you advise something else?

    Many Thanks
