Impregnation agent for your convertible: Sprayhood & Tent Protector

Protect your soft-top convertible roof with the Sprayhood & Tent Protector. This strong impregnation agent makes the convertible top and seams waterproof and dirt repellent. This prevents leaks into your interior. Another advantage is that after impregnation, green deposits and dirt cannot attach to the roof as easily. An impregnated convertible top is easier to keep clean thanks to the protective layer. The result? You significantly extend the service life of your fabric roof, meaning you can enjoy a clean roof for longer.

    For maximum effect, always impregnate your convertible top after you have cleaned it. That way, you know for sure that you are giving the material optimum protection against dirt and grime. Did you know that standard roof coating weathers quickly due to UV radiation? That is why we always recommend that owners of new convertibles impregnate the fabric roof straight away.

    A clean, impregnated roof has optimum protection against wind and weather conditions. Only use the impregnation agent on a clean, dry convertible roof.

    You do not need to dilute this special impregnation agent.

    Impregnation agent instructions for use

    1. Make sure that the fabric roof is clean and dry before applying the impregnation agent.
    2. Spray a generous amount of impregnation agent onto the dry roof. Make sure you apply the impregnation agent evenly. You could use a plant sprayer or brush to do this.
    3. Also apply the impregnation agent to the inside of the roof. If you impregnate the inside, mould and weather stains will not stick as easily.
    4. If you have a roof with a plastic window, remove the impregnation agent from the window straight away using a damp cloth.
    5. Leave the roof to dry thoroughly

    Impregnation agent applications

    You can use this impregnation agent for a variety of applications, including:

    • Polyester tents
    • Boat covers
    • Sun blinds
    • Convertible tops
    • Backpacks
    • Plastic
    • Boat cushions


    How many litres do I need in order to clean and impregnate my convertible roof?
    That depends how dirty your roof is. For a normal level of pollution on a convertible roof we recommend using the following quantities: 

    • 1 x 1 litre Sprayhood & Tent Shampoo
    • 1 x 1 litre Power Cleaner
    • 1 x 2,5 litres Sprayhood & Tent Protector

    A clean convertible roof in three steps

    Of course, you can use the impregnation agent on its own. The product works best on a clean roof. For best results, use the impregnation agent in combination with our cleaner and stain remover. Did you know that the dirt on your convertible roof is never made up of just one type of dirt? It is usually a combination of sand, algae and mosses, salt and insect and bird droppings, for example.

    Sprayhood & Tent Shampoo can be used to remove most dirt. Remove any stubborn stains using the Power Cleaner. Then apply the Sprayhood & Tent Protector or Canvas Protector to protect the canvas. Our three-step plan in a nutshell:

    1. First of all, use the cleaner to remove most of the dirt.
    2. Then use the stain remover to get rid of any stubborn stains.
    3. Finish by using impregnation agent to make the roof waterproof and dirt repellent.

    Frequently Asked Questions

    Does it matter if the Sprayhood & Tent Protector touches the plastic windows?

    It won’t do any damage, but make sure you wipe off the window film using a damp cloth after impregnating. Once the impregnation agent has dried, small marks may appear on the windows. You can easily remove these marks using Ultramar’s Plastic Window Cleaner & Protector.

    Should the canvas be dry before I start applying the impregnation agent?

    Yes. Make sure that the canvas is dry before you start applying the impregnation agent.

    What is the difference between the Sprayhood & Tent Protector and the Canvas & Cotton Protector?

    They are both impregnation agents developed to treat specific types of fabric.
    ● The Sprayhood & Tent Protector is specially developed for woven plastic or canvas that contains plastic, such as a polyester tent, boat cover or convertible roof.
    ● The Canvas & Cotton Protector is specially developed for canvas with cotton fibres, such as a cotton tent.

    Can I use the Sprayhood & Tent Protector in the sunshine?

    Ja, warmte en zonlicht versterkt de werking van Sprayhood & Tent Protector. Laat het doek dus gerust in de zon drogen nadat u het hebt geïmpregneerd.

    Audi Cabriolet

    Afgelopen week Ultramar Shampoo en vervolgens Protector gebruikt voor mijn Audi (80) Cabriolet `99. Het resultaat is bijzonder goed! Week eerder een onderhoudskit van Ragg Topp en Naarden gekocht. Helaas met een slecht resultaat. Dak was nog steeds lek. Na gebruik van Utramar Protector (ruime flacon helemaal op gebruiken!) geen lekkage meer en het water "rolt" als het ware van het dak af. Kortom een aanrader!
