How to remove silicone sealant

How to remove silicone sealant

removing silicone like this is often a
difficult job it can be quite difficult to get all that off but now there are quite a
few products on the market which will actually remove it for you and there’s
quite a few different makes of these chemical silicone removers so we’re
going to apply it all the way around the bead of silicone on the back of the sink
so that we can remove the bead it’s important when you do anything like this
that you read the safety instructions on the back of the tube so I have actually
put some disposable gloves on here because it is quite nasty stuff and it
is an irritant so now we’re just going to apply a bead around the sink and I’m
just going to leave it for between 3 and 20 hours so we’re just going to apply a
bead I’m just going to make sure that we cover the existing silicone
completely so I just need to leave that now and
then we can scrape it off using a plastic scraper so here we are now
a day later and we’ve left a silicon remover on there for about 24 hours
although I says between 3 and 24 hours in the instructions so now what we’re
going to do is we’re just going to scrape off the old silicon now you are supposed to use a plastic scraper if you’re doing this but I can actually find one
so I’ve just got a small piece of plastic that I’m going to use and again
you have to be careful with this and you need to put some disposable gloves on
and then you need to follow the instructions on your actual container and
tells you what to do with the waste afterwards I’m just going to start
scraping this off and you can see there that it has actually loosened the bead between the
tiles and the basin and you can see that actual silicone
remover has chemically attacked the silicone and it’s
loosened the bond between the two surfaces so now we’ve got all that off
we’re going to dispose of the glove’s are we are going to dispose of the actual
silicone and all the bits that we’ve used and then I’m going to clean out the area
thoroughly and then I’m going to clean the back of the sink using some
methylated spirits before I put a new bit of silicon on there so that’s the
modern way of removing silicone sealant just by using a chemical

  1. Hi, I have a spot on my home on painted stucco where apparently someone caulked an area with silicone. Would this work to remove it?

  2. Thanks for all the interesting videos. Do u think the silicone remover would knacker a vinyl floor if it was to get on it? Need to get sealant from the bath panel to the floor off.

  3. Actually I did find a product that will take off silicone residue and won't harm a vinyl floor. It's called Re-mov and I found it at a site called Silkote in Canada. They say they ship worldwide so you might want to give them a try. The site is and then click on re-mov.

  4. if i mount something with silicone, and the silicone is behind that which i've mounted, can i use a product to eat away at the silicone behind say, a wall mounted soap dish?!

  5. oops! i forgot to add–the silicone is suggested by simplehuman to mount their soap dispenser wall mount, and i would be mounting this onto tile. i don't want to ruin my tile should the dispenser fall off or if i want to get rid of it! thank you so much for any help!

  6. Go to the upvc window store and buy a container of upvc solvent silicon re mover , works in no time ans it,s not expensive … it will clean without damaging PVC windows … that what it was made for .. cost about £4 …. I'm a painter and use it most days

  7. I was searching around for a solution to remove the silicone haze from my tub and tile surround. Getting the big stuff off was easy with a razor but the haze seemed impossible. I tried nail polish remover, isopropyl alcohol, wd40… nothing worked. Then I got the idea to try the window razor scraper again, this time at almost a 90 degree angle to the surface instead of almost flat. Guess what. It worked like a charm. Don't kill your brain cells with solvent, try a steep angle with a razor.

  8. Why do you need to clean it specifically with methylated spirit afterwards?

    Is this to ensure any silicone remover residue doesn't attack the new silicone applied?

  9. Found an article saying you can use a mixture of flour & water to remove caulk. Haven't tried it yet… It was in How Stuff Works dot com.

  10. Great advice – I didn't know you could get silicone remover – will purchase some and have a go at re-silicone bath and sink! Thanks for sharing your knowledge!!! Very much appreciated!

  11. Great video, I'm literally off to a store to buy the solvent; I have a lot of it to remove given I have a leaking shower cubicle 🙁 Fed up already of trying to remove it with a blade, which is messy, inefficient & dangerous in part (for self and surfaces). I thought there must be an easier way to do this! Am worried if water is passing beneath the L-shaped trim, on top of the shower tray & behind base of tiles & then past that & into Kitchen ceiling! Well done, saved me some work no doubt!

  12. This is all set up. I bought same staff after watching video… left the smount of time it said on tube and to be honest all I could remove was this sillicon oldbone was still there evdn thought I used proper scraper then one on the video. Reterning item tomorrow back to the shop. Thanks for the vid

  13. I'm no handyman OK I've fitted a garden pond but never done anything in the bathroom . Watching this video has given me the encouragement. OK so far I haven't burn the house down… Thanks

  14. as a prank, i took a silicone gun and ran a thick bead of caulk between my friend's hairy ass. now his poop hole is totally sealed. can't shit, cant fart. could this product 'break the bond' and then i can peel it out from his butt?

  15. Will this get deep into a tight seal? I have some ceramic objects stuck together with silicone and I need to separate them safely. Great video, thanks.

  16. It's quite tricky, I think there's quite a bit of silicone behind the join on the inside. I've managed a few with a thin knife but i'd prefer something less dangerous and less likely to damage the ceramics.

  17. The prior owner of my sailboat must have had stock in 3M Silicon since it is everywhere. I want to remove it from the fiberglass. Will these removers damage fiberglass that you know of?

  18. Yes, I use WD40 as well – it works quite well, and it means you don't have to buy another product just for this job. What do you think UltimateHandyman? How does WD40 compare to the proprietary silicone removers?

  19. I've used chemical silicone removers and pretty much all are useless, the time it takes to supposedly work is just daft. I can do the same job quicker with a few tools and a some paint cleaner rags. A lot of the re-silicone jobs are on DIY attempts to silicone and believe me when I say I think they thought they had to use the whole tube and lost control of the gun while doing it. In the world of silicone, less is more.

    WD40 is probably what god uses to keep the universe friction free. lol!

  20. Hi there,could I use this type of remover on pvc trim on my bathroom window?I just had applied new trim around my bathroom window though thought I had removed the excess silicone & now a day later it has bonded to the new trim,I was wanting to just apply to overrun areas not the actual seams being I want to leave that in place what do you recommend? thank you…

  21. I don't really like that silicone remover stuff; it makes the silicone gungy and difficult to remove. I've started using a flexible sharp kitchen pushed up again the wall/tile/bath and then cut it out. My 2 cents.

  22. Great video but the stuff we used that purported to remove the silicone wasn't nearly as good.  You practically needed an atomic bomb to get rid of the silicone sealer in our shower surround.  

  23. if you need instant results, well shorter than 3 to 20 hours, i recommend using WD40, no disrespct to you ultimate handyman. As loads of your other vids have helped me out, just thought i'd return the favour…………….smily face

  24. Right. Done. Now – what's the best way to clean the surface of the silicon remover? It's left a nasty oily sticky residue that doesn't seem to respond to soap and water. I need to prepare the surfaces for new silicone. Thinners? Turps? Bleach?

  25. Stop using 2 separate faucets! That is just pure madness! How do you wash your hands? A "mixer" is such an easy system, so why not use em?!?!?! 

  26. The fastest way is to just use a razor or flexible utility knife. It won't leave a messy residue and you can immediately re-apply another bead of silicone right away. the old silicone does not have to be 100% removed, just close enough so that the new silicone will have a good contact and it will adhere itself long enough until you have to replace that. Just my honest 2 cents worth. Not trying to criticize bc you have put up many useful videos on DIYs. Keep up the good work my friend.

  27. If you plan on removing the sink and replacing, tiling, or servicing it, a strong (dacron preferred) fishing line with two dowel or stick handles can be used to cut through the silicone around the sink.

  28. Is this ok to put on a RV roof that is made out of EPDM or TPO roofs?Can it go on the siding of the RV as well?

  29. My girl used black silicone to put some wind visors on the car but the silicone is now glued to the window molding you think if I use this to removeit, it wild damage the window molding? ???? Sorry for my bad English

  30. This is just what I have to do in the kitchen. I am from Mexico and I hope getting this silicone sealant remover would be easy. Thank you so much.

  31. A friend/neighbour used this product to remove silicone sealant in their kitchen, to their horror it damaged the worktop surface. I know they should have read the instructions before using. Apparently it can also damage plastic baths, so use with caution.

  32. spray some WD40 over the silicon…It will loosen up and pull away on its own…It can be done in 1/2 hour or so.. much cheaper, faster and cleaner….no damage to the surfaces either.

  33. I ordered a tube of caulk, having never used one before, I could see it go down the spout but then get stuck and not come out so I said to hell with the spout and sawed off the whole top and just scooped out as much as I needed for the time, then left it with top exposed. I came back to it a few days later to find all the sealant in the tube completely solidified. Is there any way to turn it back into fluid so I can use it?

  34. ….between 3 and 20 hours?!!! Lol. Life's too short for that carry on, Bud. Razor blade is your friend…yeah, it's a bit of graft, but you can do another job in the morning instead of coming back to this one.

  35. will WD40 (used to remove silicone)  harm brick or mortar wall … will silicone sealant remover harm brick or mortar?

  36. I have just fitted a new black kitchen sink and I have got some silicone sealer on the surface, any suggestions for removing it.

  37. The trouble with using WD-40, which is very effective, is that even trace amounts prevent the new silicone from bonding well.

  38. Hi ultimate handyman, great vid, How long after placing the small bead behind the taps did you leave it before applying the big bead over the top..?

  39. Is it me or are the chemical silicone 'digesters' less effective than they used to be? I recently bought a small scraper which holds one of those single-sided razor blades, and because it's so sharp it cuts the silicone away from glazed surfaces very easily. If there's a trace of silicone left I then use some digester.

  40. Hi handyman, i just watched another one of your videos where you used a no nonsense silicone remover and compared it to WD40. However it seems in this video the silicone seems to remove easier. Would you prefer this silicone remover over the no nonsense and WD40? Thanks

  41. Nice. I used 100% silicone (clear) around my kitchen sink. I didn't realize what a mess I made. I want to remove it and run again taping off the area. I suck at this diy stuff but need to get it done cheap

  42. Sharp blade works well at removing the majority. For stubborn bits that remain, I've had good results with steel wool

  43. WD40 will do it, but make sure you clean afterwards thoroughly with methylated spirit to remove any traces of WD40… Once dry, reseal with new sealant using a Fuji kit…
