Fabsil Silicone Waterproofing Liquid for Outdoor Fabrics, 5L

I bought this to waterproof the roof of my convertible. After trying many (often expensive) specialist products which I have always been left disappointed with when the waterproofing washes off with the power washer I did some research and Fabsil came up a few times so I thought I would give it a go. Tips. Make sure the roof is clean and fully dried out before application. Preferably clean the roof the day before. Work on a warm day. Apply in the shade but position in the sun to dry out. I used a clean paint brush to apply and worked along the roof in strips in one direction making sure to soak the fabric with Fabsil. I allowed the roof to dry in full sun for about 6 hours then applied again but in an opposing direction to the first application again making sure to soak the fabric, again leave to dry out in the full sun. Leave at least 24 hrs until the roof gets wet. The results where amazing, water beads on the roof and never soaks the fabric, I applied this 3 months ago in September and it still works just as well as when first applied even with washing the car most weekends. I would expect this to last through winter without another application. I have a S3 convertible to give an idea of roof size, I reckon I used about 1/3 of the can so great value. The product made my roof look blacker and almost sparkle in the sun. I have a new car but would imagine that it would darken a faded roof. It does smell a bit at first but the smell soon clears after a few days. BEST product I have tried to waterproof the soft top.

I’ve used this product before and found it excellent. Read the instruction that come with the product and use in a well ventilated area. I use this for a canopy on my boat and reapply every few years

Best on the market

Pretty good - bit difficult to spray on my tent but seems to have made it more waterproof.

It does what it says on the tin,works really good

I was amazed that 1 application of this product stopped the leaks on our caravan awning and rain water has stopped pooling where it had previously built up. We bought the awning pre owned and found it leaked in several areas and on one side of the roof the rain water pooled up which we kept having to push it off. My other half painted fabsil over the whole outside (not windows obs) with one generous application. It does have a strong solvent smell but we applied it in the garden and let it dry. When we use the awning a week later on the caravan, there was still a smell but by day 2 i didn't notice it any more (I have v sensitive sense of smell). We had stormy weather and lots of rain. I couldn't believe that there were no leaks at all and I wasn't expecting the pooling water to stop but it did! I highly recommend this product, it's worth the effort of applying it. Oh and 1 can just about covered the whole awning, sides included. Awning is a Kampa Dometic Rally 390 if you need size reference :)

Great product, I use it to waterproof my pop up roof

excellent water proofer easy to apply brush or spray it on, used on my tent, Hi viz coat and my light weight pack a mac. I used a garden spray bottle to spray the tent when erected and used a coat hanger on the washing line to stray my oat and jacket and left to dry Why did you choose this product over others?: best on the market to my mind

Lo puse en el carro tienda por la mañana y por la noche ya pudimos dormir, sin olores ni nada, y esa misma noche nos calló bien de agua y no caló nada de nada.
