Impregnation agent for your boat cover: Sprayhood & Tent Protector

Use Ultramar’s Sprayhood & Tent Protector to keep your boat cover clean and waterproof. Your boat cover will last much longer and cleaning it will be a piece of cake. Impregnating your boat cover will make the canvas waterproof and dirt repellent. Mould, algae and dirt can therefore stick to the boat cover much less easily. This means you can enjoy your cover for many years to come and will make cleaning it much easier.

    We recommend cleaning your boat cover at the end of the sailing season and impregnating it straight afterwards. Always impregnate your boat cover after you have cleaned it. Cleaning the canvas removes both dirt and the impregnation agent. By repeating the impregnation process, you protect the material against dirt and grime.

    If you store your boat cover for winter storage after it has been cleaned and impregnated, you will prevent mould from developing during the winter period. This means you have a fresh cover for the next sailing season that can withstand water and dirt. Only use the impregnation agent on a clean, dry boat cover.

    You do not need to dilute this special impregnation agent.

    Impregnation agent instructions for use

    1. Make sure the boat cover is clean and dry. Then put up your boat cover.
    2. Spray a generous amount of impregnation agent onto the dry boat cover. 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 cover. If you impregnate the inside, mould and weather stains will not stick to the canvas as easily.
    4. If you have a cover with windows, remove the impregnation agent from the windows straight away using a damp cloth.
    5. Leave the boat cover to dry.

    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 boat cover?

    That depends how dirty your boat cover is. For a normal level of pollution on the boat cover 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 boat cover in three steps

    You can use the impregnation agent on its own, as long as the cover is clean before use. For optimum results, use the impregnation agent in combination with our boat cover cleaner and stain remover. The dirt on your boat cover is never just one type of dirt. It is often a combination of salt, sand, algae and mosses, mould and flies, 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 to protect the boat cover. Our three-step plan in a nutshell:

    1. First of all, use the boat cover 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 canvas 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.

    Goede service en ben tevreden

    Ik heb jullie impregneermiddel gebruikt. Eerst dacht ik dat het niet goed genoeg was. Even met jullie gemaild en toen werd me duidelijk dat het doek goed nat moet zijn met impregneer. Ik heb dus afgelopen weekend weer de tent gedaan en nu is hij werkelijk prima! Dank jullie voor de goede service.
