Uitstekend, ik had een defecte spuitbus ontvangen, maar is professioneel opgelost.

Produit prêt à l'emploi, pas besoin de le diluer, il suffit de fixer un vaporisateur sur le goulot. Avec 1 litre j'ai pu passer 2 couches sur une toile de tente 2 places. Très facile d'utilisation; j'attend qu'il pleuve pour pouvoir juger de l'efficacité. J'ai arrosé ma tente et ça a l'air nickel .

Good service and good communication.

Good service and good communication. Waterproofing product did leave a white residue on my tent but I was assured this would go in time. Tested waterproof by using hose and seems to have done the job.

Im Bestellvorgang könnte auf lange Lieferzeit seitens PostNL hingewiesen werden, es dauerte eine komplette Woche bis das Paket von den Niederlanden nach Deutschland kam. Preis Leistung vom Imprägniermittel unverhältnismäßig, 500 ML Ultramar reichen meiner Meinung für 2 große Jacken was dann 27€ kostet

CLEAN AND AS GOOD AS NEW

Being outdoors is about enjoyment.
But tent fabric, boat covers and convertible roofs take a lot of wear.

Sand, salt, dirt, mold and stains slowly damage the fabric.
With Ultramar, you clean and protect outdoor fabric yourself.

The result:
Clean fabric that stays water-repellent and lasts longer.
