Why Millions Get Silicone Caulk Wrong

In this eye-opening video, we delve into the common misconception surrounding the application of silicone caulk. For years, millions have been misled into believing that using washing up liquid, dish soap, or window cleaner during the caulking process is essential for achieving a smooth finish. However, what many fail to realize is that this seemingly harmless practice can actually lead to long-term problems.
I reveal the truth behind the widespread practice of spraying solutions directly onto the silicone and tiles during caulking. While it may appear convenient, this method compromises the adhesive properties of the silicone. When tooled improperly, the edges and areas behind the silicone fail to adhere properly, paving the way for mold growth and premature deterioration.
But fear not! My video demonstrates a simple yet effective alternative. By eschewing the use of solutions and employing the appropriate tools, you can achieve flawless results that stand the test of time. Say goodbye to wrinkly, ineffective silicone caulk and join us in revolutionizing the way caulking is done. Watch now to discover why millions have been getting silicone caulk wrong all along.

Да это и так любому нормально думающему человеку должно быть понятно

[@christophergallagher3845]

Applying the bead of silicone is just as Important if want it even and uniform without it spreading everywhere . In my own home where I have unlimited time I sand down the silicone nozzle to the shape of the corner being sealed I then mask of the lines and apply silicone and smooth down with finger . Removing the tape leaves slight ridges so I then use the soap water method to smooth over a second time knowing almost all excess silicone was wiped off in first smooth over. Takes longer but the finish is unmatched and you know that it's bonded properly

[@glennwhitlock1272]

I've always pushed the nozzle along the gap instead of pulling, which sort of injects the silicone into the gap and doesn't leave a rounded bead. So much less waste when you pass your finger along. I'm only a DIYer and probably don't know what I'm talking about, but it works for me

[@zweed69]

na 💯 bro you nailed it

[@PeterJ-ij6mm]

100% correct. A professional cuts the nozzle back to a larger diameter and then pushes it along the joint. No need for fingers, liquids or tools if done this way.

[@armoris66]

Never use your finger. Oils allow bacteria to form = mould; use tools whenever possible. However, if DIYing it you probably don't want to go to the expense of buying tools.

[@robertgraham2926]

After 35 years doing kitchens and bathroom renovations that's the best method in my opinion. Cut the nozzle flat, not on an angle and push.

[@ScratchyBaws]

Met a guy 30yrs ago and all he ever did all day was silicone kitchens after they were fitted and he showed me to just dip/dab a finger in part water part washing up liquid in a wee glass then finish off your silicone bead with that finger. Also it helps to cut the silicone nozzle correctly and apply evenly. Practice makes perfect

[@evanpenny348]

Professional tiler for 25 years - retired now. Agree with this 95% but pushing the tipis definitely correct, for reasons given by others below. Also do not agree with the no fingers brigade. You can use your finger to shape the silicone, does a great job, but wet finger first or silicone will adhere to the skin and make a terrible mess. Also, note that mold growing on your silicone IS NOT caused by licking your finger. It is caused by the gap between the tiles being unclean. Always used toluole to clean all grease and oils off the joint area before applying the silicone. Well, that's my two bobs worth.

[@selflession]

To be honest I'd never even heard of spraying the tiles with water and washing up liquid as a thing. It seems completely counter intuitive to me. You want a clean, dry, dust free surface for the silicone to stick to so why you'd then want to put water anywhere near it until it's dry is beyond me. Great video though, as always.

[@seanmellows1348]

Excellent demonstration. I’ve been a tile guy 20 years, started using soap water only in the last several, on account of Sal Di Blasi. I must adjust my technique, I’m certain to have some poor caulk out there. The challenge is with lumpy tiles, uneven stone, and cushion edged mosaic tiles. I can’t get a tool to work, finger finish is always required. Spray prevents spreading and smearing.

[@jdoogg100]

Exactly he didn't have a grout line to deal with or bumpy tiles

[@grrinc]

I mostly tackle bumpy tiles by using the silicone tool in both directions and maybe adjusting angle. Not perfect, but better than one pass. I always informed customers that silicone bead will follow bumpy tiles and ridges

[@jtcheng84]

When really bumpy or if there is a stark contrast in silicone colour to the surface colour, I use green painters tape to get it pretty close to a straight line before tooling.

[@webbo73]

Great demo - I've never used washing up liquid for this - didn't even know it was a thing. Best discovery I made was using the profiling tool rather than just the finger to stop it going concave.

[@MrJohnnyboyrebel]

Sorry if this is redundant, but I made the mistake of using an expired tube of silicone sealant. I had no idea that silicone has a finite shelf life. It was printed on the tube but I didn’t bother to look. Not only would it not skin, but it would not set up at all. I have to scrape it all out and get a new tube that had not expired.

The washing up spray method is ok but can leave flappy edges, plus, getting sealant wet while it’s in a liquid state can introduce bacteria to the surface making the sealant discolour, as I had to do mastic work professionally I moved on to a “Cramer Fugi Kit” these are professional sealant tools that give a much better finish as the job is kept dry, they also have a brilliantly simple attachment to stop the dents you get in the finish when the smoothing tool drops into the grout lines, this kit is not easy to use and will, (like every skill) require practice. Having learned how to use these kits you will look forward to mastic work instead of dreading it.

[@noire1001]

The main reason for peling silicone is because everyone just buys the cheaper acetoxy silicone. Spend a little more and get low modulus neutral cure silicone. Its thicker, easier to tool and will last much longer. Cheaper 'general purpose' silicones are not fit for purpose and a total waste of time. If it smells like vinegar, you got the wrong stuff.

Not sprayed directly) a few spots that didn't tool cleanly, but I got a spot or 2 wet ahead of me caulking. Didn't stick at first tried to brute force it I guess wanting to get the job done. Carefully dabbed with paper towel it stuck then I tooled it. Am I going to have adhesion issues where a little mild soap water / residue could have been between counter and porcelain? It's maybe two 1" spots but enough to irritate me. Caulk was injected well and completely filled, tooled not concave. Will the silicone caulking absorb some part of that or nullify it & adhere? Water dries and silicone adheres? Since it's not exposed to air to dry while it's wet? Thoughts? 🤣I'm experienced but no pro.

Partly agree... There are infinite ways of doing this. *Using only fiber or rubber leaves thin marks on sides of gap, after some time they become visible...

Proper preparation is key. Ensure tiles are clean and dry and finish off with a clean cloth and meths and allow that to dry before applying silicone. I retiled my shower 7 years ago and applied silicone along the corners and usual grout elsewhere. Silicone is as bright as the day it was applied and grout has slightly discoloured as expected. And yes, I do take showers regularly!

"Meths"? What is that...methylene chloride? I have 60 yr old tile laid in mud and one spot still rejected the nice water fingered silicone bead that I laid down (squirted into gap using push method) in spite of a final prep with isopropyl alcohol. Please clarify meths... for a desperate Yank if you don't mind? [Yes... filled the tub with water for a day while drying]

[@russelldawson9560]

In US I think you call it denatured alcohol@@dhgmllcshea5038

[@kathydoyle1857]

​@@dhgmllcshea5038 I think he means Methylated Spirit (which I think has a slight blue colour to it). But do some research first and also search for White Spirits. Both are very strong smelling and need to be used in areas with good ventilation. We also have White Spirits (clear liquid) that we use here in UK all the time for a number of jobs.... painting jobs...it cleans your brushes of oil based paints So it removes grease. It can be used to thin down oil based paint. It's also used to clean bare wood of any grease and left to dry, then sand down before using wood stains. Hope this is of some help.

I'm a commercial caulker and all I use is slickers ( caulking spatula) made by Albion. They are made out of stainless steel and come in different sizes, I even have ones that are off set. The better bead you have the easier it is to tool. We also use backer rod that comes in different sizes that are used to put in the joint. Just remember you never want to have a 3 way bond.

Cleaning the corner first with denatured alcohol always helps the bond. Gets rid of any possible oils and dirt.

I’ve been using a weak washing up liquid spray for 20 years in over 300 bathrooms, never had a single problem. In fairness your bead laying is shocking, your test pieces are are super smooth and flat ceramic, try doing your test on a rough riven tile or a split face tile. I’ll continue doing it the way I know works for me.

[@THE-AIDEN-PROJECT]

That's fine, you do you 👍 I've done riven slate before without needing soapy water 🤷 there's been a few people saying the beads were shocking, the average DIY'er would lay down similar though and that's why I've shown what happens. If you laid down the perfect bead, logically you wouldn't need to use soapy water in the first place 🤷

[@christophergallagher3845]

He's right about the film , his initial application is shocking though lol may aswell not even use the nozzle 😂

[@christophergallagher3845]

​@@THE-AIDEN-PROJECT I try lay as close to perfect bead at first and then smooth over lightly . If there's excess silicone left ill then spray iver it knowing my seals made and can take off the excess without the wall material getting covered, not an issue on tiles but on textured wetwall and stuff it definitely matters . Combine both methods if you know how both work/fail . Like you say though common diyers need it made si please for them as they're following instruction rather than having an understanding as to why they're doing it

[@grantskelton1219]

Absolutely. Totally agree. Those beads were shocking.

basic physics and chemistry, soap prevents adhesion.
