Marine Ultra Proofer

Please note: It is advisable to test on an inconspicuous area prior to use, as some colours may appear lighter or darker after application.
Do not apply in direct sunlight, as this will cause the Ultra Proofer to dry out too quickly and produce an uneven result.

How to re-proof your boat cover

1. Dry brush the boat canvas to remove any loose dust/dirt.
2. Pour Ultra Proofer into a suitable container/bowl.
3. Stir well before application.
4. Apply Ultra Proofer with a new 5cm/2inch paintbrush ensuring that the fabric is completed covered. It is best to commence application in the centre of the canvas and as quickly as possible progress towards each side, front, and back of the boat canvas. Wipe excess drips from bodywork, trims and glass with a damp cloth.
It is important to allow Ultra Proofer to dry between coats. Always ensure that you have enough Ultra Proofer to coat the boat cover completely and that you will not run out half way through application!
5. Allow the boat cover to dry for approximately three hours, this will depend on the drying conditions. The Ultra Proofer may dry out more quickly if it is a warm day and may take longer to dry if it is a damp day.
6. Wash out brush in warm, soapy water.

Do not expose the boat cover to rain/wet weather until the Marine Ultra Proofer has completely dried.

The boat canvas is now water and stain repellent, will resist the growth of mould/mildew and is protected from harmful Ultra Violet rays.

To ensure best possible weatherproof protection we advise that Renovo Marine Ultra Proofer is applied every six months.
