Review: Worked a treat - First pictures show the state of the seams on our tent before. Old sealant was peeling off and came off very easily. Last two pictures show the after. Found it relatively easy to apply.. wool setting on the iron and greaseproof paper between, leaving it on for 5-7 seconds as the listing suggests. One or two bits didn’t stick as well but with a little bit of trial and error I got the whole tent done. Luckily had just enough tape from one roll to do the whole tent. Tent is a 3man (I think) domed tent. Would recommend and use again.
Review: Good product but overpriced - I used this to reseal the seams on my bivvy as the original had lifted in many places due to poor storage conditions. I've used much cheaper tape before with the same application method and have had the same results so i did think it was overpriced and would not purchase again for that reason. Application is a little fiddly and the parchment/greaseproof paper doesn't work. I use a teflon baking sheet and that never sticks at any temperature. Use a piece of wood just a little wider than the tape and wrap a cotton tea towel round it as the ironing surface, this will stop the surrounding area of the fabric getting too hot. The iron needs to be medium hot and will need some pressure for at least 3 seconds upward depending on the thickness of the seams. If you touch the tape with the bare iron plate it'll stick like the proverbial sh.t to a blanket! It's a time consuming process but if you do it right it gives a good neat factory finish and seals really well. This is a good product that when applied correctly and not rushed will give a factory finish but other tapes do the same thing at half the price.

## Questions & Answers

**Q: can this be used on goretex and / or nylon?**
A: FX-800 Seam Tape is not suitable for GoreTex which has a PTFE waterprook laminate. It is designed for use on polyurethane (PU) coated / laminated waterproof fabrics and will only adhere to the PU coated side of the fabric (it will not adhere directly to un-coated nylon or polyester). Our seam tape quality T-2000X will normally adhere well to GoreTex 3 layer fabrics - this is a versatile tape and will also adhere to 2 layer fabrics.

**Q: I have a raincoat made of ripstop nylon.  The current clear seam tape is coming off.  Would this likely work to re-cover the seams?**
A: This should do the job. However please note that the tape will only adhere to the PU coating on the inner side of the rip-stop nylon so if the existing tape has pulled away the coating leaving just the nylon you will have a problem. Be very careful removing the existing tape to avoid this occurring - suggest you heat the tape with a domestic iron so it can be remover without damaging the waterproof PU coating. Best of luck.

**Q: Will this work on canvas?**
A: No but suggest you try our Seam tape T-2000X (22) which normally adheres well to canvas.

**Q: Will this work on Sil-Nylon?**
A: The Tape will only adhere to polyurethane (PU) coated nylon. If the abbreviation "Sil" relates to silicon as we suspect then unfortunately it will not adhere to this - silicon is a low cost option used on some fabrics to repel water and it pretty much repells everything including the tape adhesive.

### ⭐⭐⭐⭐⭐ Seals SILnylon effectively but be patient when applying it!
*by R***E on 1 October 2022*

Used this tape to seam seal a pair of waterproof trousers I had made from SILpoly. Care and patience is required in its application but the result seems good. Best arrangement I found was to lay the garment (inside up) with the seam lying along a length of wood about 30mm wide (ie a little wider than the tape) and with a remnant of a soft fabric ( I used and old thickest T-shirt) between the wood and garment. Run the tape (inside of the roll downwards) along the seam. With an iron set to 'wool' and a piece of greaseproof paper between it and the tape press firmly moving the iron back and forth over the tape. The dwell time and pressure need to be experimented with but a guide, quite high pressure and several second dwell time. The remnant of material between wood and garment allowed the seam stitching to 'sink' into the material and so present a flatter profile to the iron. Be patient and test your set up first to perfect pressure and dwell.
