Grangers Waterproof Fabsil GOLD Silicone Concentrate, 1 lt UK,Black

Really good product does the job perfectly. Used it on my camper pop top.

In early December I bought a 2015 Golf 2.0 Diesel Cabrio. It had been for sale in Scotland for a couple of months which were mainly very wet. When I took delivery locally it was also very wet and the roof fabric, whilst not leaking was holding a signicant amount of water and needed some attention. Reading up on how best to do this I came across an Amazon review by contributor 'Camelspanker' on 21 June 2018. recommending using Fabsil Gold. I followed his method using Johnsons Baby bath liquid in 5 litres of warm water, I also added a short measure of Milton to this as a means of sterilising/neutralising any mold etc spores. The hood had dried off in my garage before I started and using a soft brush it was easy to work up a good lather which I left in place for a while before thoroughly rinsing with clean water from a hose. Any small spots of green algae can be easily also taken off with a toothbrush and dilute milton, rinse again and when all dried off the Fabsil Gold can be applied. I was fortunate as february was not too cold and pretty dry. I applied the Fabsil Gold outside starting with shaking the can and pouring the contents into a flat bottomed plastic container as required. I used a new 2 inch synthetic bristle brush and painted the fabsil on generously in sections, keeping a wet edge available to work on from. It was pretty straightforward but make sure you have wipes available for stray splashes on windows or bodywork. If left to dry they can be stubborn to remove. I used about 3/4 of a litre of the Fabsil, also when applying make sure you give the seams and fabric 'gutters' a good coating too. and after two days I gave it a good watering from the hosepipe spray nozzle and was delighted to see excellent beading on top/sides of the fabric and no obvious absorption. By all accounts this treatment should last a good 6 to 12 months and hopefully in my case will help the hood last a few more years before needing replacement. This product certainly seems better than ordinary Fabsil and given the benefit, seems well worth the price, it also seems to have refreshed the hood appearance.

Very easy to apply with a brush. Very strong chemical smell that lingers for days. Used on tent and clothing. Darkens some material and can leave a "tide mark" (see trousers where I applied just to bottom of legs 4 days ago). Probably affects breathability of clothing. States Goretex is a trademark but does not reference use (or not) on Goretex. Longevity not tested yet. I've tried to find out whether it contains forever chemicals. If it doesn't then it would be good if it stated that it is PFAS-free!

I followed some instructions from a website in preparing the soft top for waterproofing which were roughly wash with very mild detergent and soft brush, rinse well, brushing as you rinse. inspect it thoroughly. I found 3 spots where bird poo had really soaked in. I suspect it was seagulls as with the high fish content that stuff is like glue. I used a stiffer nylon brush and mild detergent to remove this and rinsed well. Leave to dry. I was lucky in that I had a couple of dry days to do this. Once totally dry, hoover the soft top using a soft upholstery brush to remove residual dust and debris. You should now be ready to apply Fabsil. I decanted it to a pot and held this above the areas I was painting to avoid drips onto the paintwork. Have an absorbent cloth or tissue to hand in case of run-off. Depending on the level of retained waterproofing in the soft top it will take different times to absorb. Mine was quite bad (no beading when water was on the surface). My first coat dried in almost as quickly as I applied it. I left it at least an hour between coats or until touch dry. I applied 4 coats in all (small soft top). They took progressively longer to soak in and dry but even the last coat looked visibly dry after 15-20 minutes). The application of Fabsil has made the top look better (slightly darker) and rain / dew just bead on the surface and run off when I pull away or can easily be dried with a garage towel. Don't rub when drying just lay the towel across the surface. It may need an extra coat every 3-6 months to keep up the waterproofing, I did mine about 3 months ago and it's still holding up well through some particularly wet days. I also think as the material has absorbed the waterproofing it has tightened up. A few little rattles I was getting before application have disappeared now. When I purchased the car I was in two minds as to whether to replace the top, but what it actually needed was a good cleaning and re-waterproofing and it's looking pretty much as good as new.

As expected good brand good price

I bought this for a £30 tent I bought in 2014. Water used to come through in the mornings when dewy and I was worried about rain getting in. I applied as per instructions and let it dry; it rained twice and the water beaded on top which was fantastic. No water came through the tent and the tent wasn't damp or wet on the inside. I missed one inch of the tent and could feel the difference between that and the rest so a really obvious difference! Easy to use, applied with a paintbrush. Smell is somewhat chemical at first so wear a mask/apply outside and leave to dry as per instructions. Used on a four person tent and only used a quarter of the bottle. Will use again for other items/won't be without it!

Easy to apply with a brush onto campervan pop top roof canvas. The canvas was red and this was painted along the end seams and stitching due to previous leaks at these points. The packaging warned that there might be some colour change when applied but I was really pleased that when it was dry you had to really be looking for the colour difference to notice it as it was very subtle. In regards to waterproofing, I have not yet had the opportunity to test it as it has not rained when in use yet. However, I am confident that it will do a good job as this stuff came highly recommended from a camping group I am a member of. The tub is huge and only a little is needed so the listed coverage should be achievable making it good value for money.

Have a Mazda MX5 soft top of about 8 years age. Had recently noticed some water droplets on the inside roof. Thought I was going to have to replace the whole soft top but then I read about this product in a search of similar problems with vinyl roofs. I bout the item and proceeded one afternoon to (a) clean the card down as normal (b) give an extra scrub down to the vinyl roof removing any green alge etc that had developed (c) allowed to really dry out in some nice warm sunshine then (d) apply 2 coats an hour apart of this product on every inch of vinyl I could see. Allow to dry out overnight. The result was fantastic....when it rains now I just see rivers of water droplets being repelled and running down the outside of the roof - never had any water inside again! WORD OF WARNING - Do not allow the solution to drip, spill or run off the car onto your drive or block pave, it seals that section too meaning when it does rain you get a dry spot/section when everthing else on the drive is wetlook. I know it happened to me in 2 small sections so be very careful or put down paper/sheets around your car if you are working on the drive. Brilliant product. Hope this helps.
