View description
Fabsil Super-Concentrated Gold Universal Protector treats your tent, awning, or outdoor fabric gear with professional-grade waterproofing that actually lasts. This isn't a basic spray. It's a paint-on formula that bonds with fabric fibres to create a barrier against rain, dirt, and stains while maintaining breathability. The 1-litre bottle covers 15-18 square metres on standard tent nylon, making it enough to treat a typical 4-6 person tent completely.

The application takes about 20 minutes for an average tent once you've got your fabric clean and dry. You brush or spray it on, making sure seams and high-wear areas get extra attention, then wipe off any pooling. Most people use it on their tent flysheet, groundsheet edges, and any cotton or polycotton panels that tend to leak after a season's use. It works across nylon, polyester, canvas, polycotton, and ripstop materials, which means you can treat all your camping kit with the same bottle.

One thing to know upfront - you'll need outdoor space or serious ventilation because the fumes are strong during application. The treatment needs 24 hours minimum to cure properly, though leaving it 48 hours gives better results before you pack everything away. Most campers apply it at the end of the season or before a trip where wet weather looks likely, rather than trying to fix leaks mid-camping trip.

Frequently Asked Questions

How much area does 1 litre of Fabsil Gold cover?

One litre covers 15-18 square metres on lightweight nylon tent fabric, which treats a typical 4-6 person tent flysheet completely. For lightweight canvas the coverage drops to 7-10 square metres, and medium-weight canvas gets 5-7 square metres per litre because the denser weave absorbs more treatment.

What's the difference between Fabsil Gold and regular Fabsil spray?

Fabsil Gold is super-concentrated and applied by brush or spray bottle, giving deeper penetration into fabric fibres for longer-lasting protection. The aerosol spray version applies faster but sits more on the surface, making it better for quick touch-ups rather than full tent treatments. Gold formula typically lasts 12-18 months of regular use compared to 6-9 months for spray applications.

How long does Fabsil Gold take to dry and cure?

Surface drying takes 2-4 hours in warm conditions, but proper curing needs 24 hours minimum before packing the tent away. Leaving it 48 hours gives better waterproofing results because the silicone treatment fully bonds with fabric fibres. Apply on a dry day and leave the tent pitched or hung up during the curing period.

Does Fabsil waterproofing stop tents breathing?

Fabsil Gold maintains fabric breathability by creating water-repellent coating at the molecular level rather than sealing the weave completely. Canvas and polycotton tents keep their natural ventilation properties after treatment, which prevents condensation build-up inside. Only apply to outer flysheets on double-skin tents, never to inner mesh panels.

Can you use Fabsil Gold on tent groundsheets?

Yes, Fabsil Gold works on polyester, nylon, and PVC-backed groundsheets to add extra water resistance along seams and worn areas. Focus treatment on the edges where groundsheets typically leak first and any patches where the waterproof coating has abraded away. For separate footprint groundsheets, treat the underside that contacts wet ground.

How often should you reapply Fabsil to a tent?

Most tents need retreating every 12-18 months with regular use, or when water stops beading off the fabric during rain. Canvas and polycotton materials need annual treatment because they absorb more moisture than synthetic fabrics. Tents stored damp or used in coastal areas with salt air degrade faster and might need treatment every season.

Excellent Water Repellent Coating

by Peteh55 (19 Nov 2019)
5 star review(5/5)
Have used Fabsil on tents etc for years, now I've used it on my car soft top. It's given great water repellency, the rain just runs straight off!
It's easy to apply with a brush or spray bottle, just make sure you take notice of the safety warnings.

had been looking for a decent waterproofer for the tent for a while. Good product easy to apply and can be used on clothes, rucksacks and trousers as well. Coverage was okay as I wasn't sure how much I would need (6 birth tent). Will certainly purchase again.

Easy to apply with paintbrush and this avoids getting overspray as with other products. Working well at repelling and beading water after 3 months.

Good For Cabriolets

by Mr B Stirling (09 May 2017)
5 star review(5/5)
Always good Fabsil is. I use it on my car fabric roof. I have to apply a fair amount. (A full tin) in one setting but it does bead the water for the full winter/autumn months. I guess I use a whole cab because the weave on the roof is wider than a tent

bought 2 cans to do a gazebo with a sprayer, you need that much. worked really well. DO NOT BREATH THIS STUFF IN, READ THE INSTRUCTIONS AND TAKE THE SAFETY WARNINGS SERIOUSLY.

The gazebo is now completely water tight and the liquid is completely invisible once dry.

Highly recommend it

Leaking Shade Sail

by Peter A. (29 Jul 2016)
5 star review(5/5)
We bought a new but cheap shade sail which proved not to be waterproof, it was then replaced by the vendor and the replacement also was not waterproof. As we now had two we decided we could afford to experiment and modified one and used FABSIL to waterproof it properly. We now have a garden shade we can shelter under in both sun and rain. One small problem was that we had to use a magnifying glass to read the instructions

Superb waterproofer for the soft top on my 10 year old convertible.
1 ltr is enough to give the roof 2 generous applications. I would therfore recommend buying 1 ltr each year and applying spring and autumn.

Needed to re seal the tent, that I am using for storage, little holes have been appearing so taped them up first and applied this with a sprayer, the litre didn't go very far so I have had to order more.

Keep The Rain At Bay

by Rasbray (29 Jun 2014)
5 star review(5/5)
Well guys it really does what it says on the tin with great efficiency.
I have an eight year old polyester fabric tent made by a very prominent tent maker (name to be kept) who when I conntacted them for assistance for my leaking tent - it was worse than a sieve - they basically wrote it off, nothing they could suggest.
So look I looked a the Fabrisil spec and the gold ticked the boxes - and it did.
I have now got a useable weather resistant tent again.

Fabsil Weather Proofer

by Mr. Richard Heath (27 Apr 2014)
4 star review(4/5)
The soft top on my MGF is quite old, probably the original from 1996. Whether it's ever been re-proofed is anyone's guess.
I gave it a couple of coats, used the whole tin. I absolutely drenched it! I did cover the seats with a plastic cover and over the last few days it has been raining, slight bit of moisture on the plastic. Got another tin coming and I'll give it another thick coat. That should do it, hopefully. It's really easy to put it on, just slap it on and it dries as if nothing has been there. There's no hint of colour so I would presume it would be fine on any colour of hood. But don't quote me on that!

Good Stuff.

Did what i wanted.Proofed my hood for my sidecar and it stayed dry, even in the recent deluge.Does help to clean surfaces thoroughly.
