Impregnation agent: Sprayhood & Tent Protector

Awnings, shade sails, outdoor cushions, and backpacks
For outdoor fabrics that are left outside for long periods.

Ideal after cleaning, before storage, or at the end of the camping season.

Sprayhood & Tent Protector is specially developed for synthetic outdoor fabrics exposed to weather, dirt, and daily wear.

Think of boat covers, convertible tops, and tent fabrics tested daily by rain, UV rays, bird droppings, and green deposits.

What makes this spray different from regular waterproofing products:

Penetrates deeper into the fibers
For stronger, longer-lasting protection – even in heavy rain or strong sunlight.

Allows the fabric to breathe
Prevents suffocation of the material and helps retain its natural texture and color.

Reduces the risk of dirt, water, and buildup
The repellent layer helps prevent sand, algae, bird droppings, and moisture from sticking. This lowers the chance of mold and green growth.

Proven effective
Recommended by sailmakers and outdoor professionals. Used in over 500,000 treatments.

With this product, you give your outdoor fabric a layer of professional-grade protection – without compromising safety or sustainability.

For best results, follow these steps:

Step 1 – Make sure the fabric is clean
Always rinse off dirt and dust with water first. For optimal results, clean the fabric beforehand with Ultramar Sprayhood & Tent Shampoo or Power Cleaner. Then let it dry completely.

Step 2 – Apply the product generously
Spray evenly onto the dry fabric. Make sure the surface is well saturated. Use a soft brush if needed to work the protector deeper into the material.

Step 3 – Let the fabric dry for at least 24 hours
Allow the treated fabric to air dry. Sunlight and warmth are no problem – they actually enhance the effectiveness of the impregnation.

Step 4 – Need extra protection? Apply a second layer
For older or more delicate fabric, we recommend applying a second layer after the first has dried.

Not suitable for cotton fabrics.
Use our Canvas & Cotton Protector instead.

Usage depends on the age, thickness, and quality of the fabric. Older or heavily weathered fabrics absorb more.

Average usage per application:

Awning (polyester): 2.5 – 5 litres
Convertible roof: ± 2.5 litres
Boat cover (sloop): ± 2.5 litres
Small sprayhood: ± 1 litre

For best results:
Apply the protector generously on clean and dry fabric

Impregnate multiple times in a row for a strong water-beading effect

The fabric is saturated when it no longer absorbs liquid

Note: Older, dull, or dried-out fabrics may require an extra layer for optimal protection.
