If you are re-siliconing around a bath, shower enclosure or in the kitchen, it's a good idea to remove as much silicone as you can, particularly if the existing silicione has gone mouldy or is susceptible to mildew build up.
However, there are situations where it's not necessary to remove the silicone as I will be explaining in this video.

  • Oh Man! Thank you for confirming this! Had to do an awkward thick bead over kitchen sink under window sill today. Came out a bit wavy as the stuff dries so quick between the mess and the tooling. Gonna go over it with another coat and soapy water to smooth it out clean. Relieved to see it sticks that well even to old silicone.

I also like how you explain why it is important to use a tool. I had always used my finger, but as you showed, this leaves a concave imprint on the bead. I will go get one of the tools you recommend and use it from now on. Videos like this are great, you prove your point well and help a lot of people!!! YOU ARE THE CAULK MASTER!!

    • Charlie DIYte: Charlie, many thanks for the acknowledgement - wasn't expecting it! Yes, good to use water and detergent to remove any greasy buildup on the silicone - we all know it exists, that's why we have to clean our baths from time to time. But it's essential to then flush away any trace of detergent using plenty of water as detergent is a perfect silicone release agent. Lots of flushing is the key. Merely wiping with a wet cloth, while it will dilute the traces of detergent, will still leave some traces as the water evaporates. This is a common misunderstanding amongst people trying to clean any surface prior to getting anything to stick to it. Rub to get the worst off, then flush copiously, allowing the surface to drain off at an angle and then dry without wiping. This applies to degreasing solvents as well as water. In industry, hot vapour degreasers offer the best cleaning but are beyond the scope of DIY because of cost, the hazard of inhaling hot solvent fumes, and the need for regular maintainence. And I can vouch for the effectiveness of a 45 degree edge. There's a golden rule in industrial design when casting or moulding rubbers to bond to a rigid item, that there must be a 45 degree edge, either machined into the rigid item or built into the rubber mould. A 90 degree edge fails at a lower applied stress because any mechanical load including temperature cycling, results in a higher stress concentration at the edge of the rubber and so reaches the strength limit sooner and encourages peeling. A 45 degree edge allows the stress to taper off towards the edge due to local flexing of the rubber, so the stress at the edge is minimal and therefore offers the best resistance to separation or peeling. Hope this is of help to everyone generally.

They've also used silicone to fill the tile edge that meets the bath and I just can't remove it no matter how much scraping I do so it's great to know I don't need to do anything extensive other than remove the mouldy silicon, clean and reapply.

  • This was really helpful, thanks for sharing Charlie. Off topic, my shower grouting is cracked in between the lower tiles. I tried to re-grout after watching your tutorial but the results were messy. I’m hopeless with DIY. I’m going to be selling my property soon hopefully and I can’t afford to have a professional in to do the job properly. Can you recommend something that I can fill the tiny cracks? I’ve seen various products on Amazon, one being a white liquid rubber product that has good reviews and can be applied using a paint brush. I’m at my wits end and currently have polythene sheets stuck with Gorilla tape to prevent damage to the actual wall behind the tiles. Any suggestions would be greatly appreciated. 🙏

  • I'm glad this video just tells it undeniably. So many sites say you can't though look closely they are either major builders or the silicone manufacturer - go figure the motives! Chemically speaking so long the silicone is the same the new silicone has no way of 'knowing' whether the last layer just cured is fresh or old. The real issues are due to a layer or grease / dirt / mould which obviously DOES make a big difference. An interesting counter case: in the toy model world they have the opposite problem of having to deliberately spray a barrier between the silicone mould and the new casted silicone material so that they don't stick - so it can't be that in one industry the chemical properties suddenly behave differently to another!

  • Great videos on caulking and appreciate the empirical testing on silicone on silicone. One question, I know on the other video you did not like to tape above and below the caulk, because the thin ledge/lip created on the top edge acting as an obstacle to down flowing water. But I wonder would that really be a problem on the bottom side since the water would flow over the bottom edge (assuming you're doing a 45 degree or convex bead?)

    @ly776@ly7765 жыл бұрын
    • The thing is, you don't want a concave profile, and if you use the FUGI or similar forming tool there's no need for any tape, top or bottom. The silicone I did in this video looks as good today as it did 2 years ago because the diagonal profile is so strong. The lip created by the tape will become a breeding ground for mould.

If I decide I want to do 10mm, do you think I can just lay more silicone down over my current bead after I degrease it with denatured alcohol and tool over the old bead? Or do I have to remove the entire original 8mm silicone and start over? Thanks!

Just put a clear silicone along the wall behind taps (can't tell it's been done obviously) so hope that fixes it. Touch dry just now but seems to have done the job.

  • I have to fix a botched blobby silicone job done several months ago. None of the joints are flush with the surfaces and there is plenty of cavity left to fill. If I understand correctly, I can clean the existing silicone with methylated spirits (deantured alcohol here in US) and once it evaporates, the original silicone will be OK to caulk over. It won't degrade the silicone? I removed a bunch of slop from the tiles with mineral spirits (white spirits in UK I think) trying to be careful not to touch the joints. Will that cause a problem if it did touch the joint or will the methylated spirits be able to clean it away? Thanks for the video, I agree with your technique as you were able to prove all your points. Thank you for taking the time to explain everything.

    • Hi Vicki, cleaning is always a tricky one as some solvents like acetone can damage plastic or acrylic baths/ shower trays. We have a cleaner in a spray can here called Multi-Solve which is great as it removes silicone but also evaporates without leaving an oily residue. You can never use WD40 for that reason - it's very hard to remove the oil and so the new silicone often degrades almost immediately. In answer to your question, I think there's a risk the methylated spirits will degrade the silicone. I can't remember whether I swiped it across the existing siliconing as in the video you only see me using it on the shower screen section which I'd totally removed the silicone from. My advice to you would be to use a degreaser like sugar soap solution or Zinsser degreaser and cleaner, rinse it thoroughly afterwards and then when it's fully dried you're good to go.

I ordered the cramer profiling kit 5. I also ordered the best fish tank sealant you can buy. After stripping the old sealant off of the tank, I found that on the bottom, of course, that the bottom piece did not contact the side glass and instead they just filled in the gap which is about 14mm. Using the 16mm is cutting it very close, but i am determined to give this a try. What is the chemical you use to clean the old caulk? The site of leak is on the opposite side of the tank just to mention. I can send pictures if needed, which may help alot. What is your opinion on this issue? Also is their something I can use to deal with this wide gap in the tank? All other parts are close together. Any help would be greatly appreciated and passed along to others.

I haven’t ever seen it NOT fail either. When sealing anything the number one rule is to over prep the area you’re going to seal. This includes roughing up the surfaces and cleaning it of any oils before you continue. Removing existing silicone is extremely labor intensive. Sure, the bulk is removed easy enough but what’s penetrated into the surface area is fairly permanent creating a big problem because it won’t stick to its self let alone anything else." Q: If not silicone, what would you suggest for a bathtub? A: An acrylic bathroom caulk containing a mildewcide. It may not last as long as silicone on a NEW installation, but it will be a lot easier to remove and replace than silicone.

  • Watched all your silicone videos before having my first go at it yesterday and have found them all super useful. One thing you didn’t mention, it’s like working with marshmallow fluff! So glad I had some decorators wipes on hand or I’d likely still be stuck to the kitchen. 😂

    • Yes, decorators wipes are a great thing to have handy. I tend to clean off the silicone in between runs with tissue, having a bin handy to put it in, and then at the end of the job I give the tool a good clean with a decorators wipe. How did you get on?

  • Why is soapy spray so bad for silicone? Surely it will not penetrate beyond the surface? Silicone dries under water. Please elaborate as I am confused.

    @LEO-xo9cz@LEO-xo9cz2 жыл бұрын
    • Because the soap invariably gets into gaps that the silicone hasn't yet bonded to, and once it's in there, the silicone will never bond to that surface meaning water in the shower will instantly penetrate the joint.

  • Your video was great. I bought the Cramer set with the scraper. I completed 2 vertical lines for the tile above my bathtub. I’m letting it dry and then I’ll do the horizontal lines so that my inside corners don’t get messed up. The only thing I didn’t understand in your vid is when you showed the 45 degrees vs 90 degrees... they looked the same to me in the video.... :-(

    • Hello my dear, I already realized that you can get the same width of cilicone, but not as thick as it is when you cut it 90° , so with a 90° line, the line you get would still be thicker, which is better to avoid having some gaps. Thanks!

  • Hi, in the U.S. what did you use to clean the silicone? I want to clean where a new bead will butt-up against an older bead and want the best possible adhesion. Either that or I remove it all and start new. I removed a section and it was slow going with a razor knife. I might need a chemical if I strip it all out. Thanks.

    • Are you wanting to keep the existing silicone, in which case you want a degreaser like acetone. If you're wanting to remove it, Google "silicone remover". I'm afraid I'm not totally up on what the best products are in the US.

  • I need help with my bath tub and I hope you can help me! I really need to re- silicone my bathtub. I seem to have a lot of movement with my bathtub and every time I redo the job it is only a matter of months before I seem to be doing it again. I have Mapesil AC to do it this time round. Do you have any tips for me? Should I fill the tub up with water for example to add extra weight...? Thanks in advance.

    • Sort out the movement of your tub first, use L brackets to secure it to the wall from underneath. Check the legs are levelled, I've even used bricks with a bit of wood on top to wedge under both ends of the bathtub to limit movement. Mapei is a good silicone, i use it for its colour range, it goes off quite quick, so be ready to smooth off.

  • The sliders that fit on the side of the Fuji sliders are great to give a smooth finish but if you need a second, final attempt you may have to take off the sliders. Using a diagonal finish is a real discipline 'cos you cant just finish it off with your finger so use the above suggestion for a 2nd attempt.

    • Interesting tip. Presumably it doesn't degrade the silicone, just reduces the friction when you scrape it off - so the primary benefit is not damaging the surface.
