MY 12 GOLDEN RULES FOR THE PERFECT SILICONE JOINT
- De-grease joints first with methylated spirit or acetone
- Use the right silicone for your joint - high or low modulus
- Use a FUGI Silicone Profiling Tool
- Look for the greatest gap & select smallest tool to cover gap + 2/3mm
- Cut the silicone nozzle at 90 degrees ie straight across &
- Push the silicone into the joint
- Aim to cover 2 not 3 sides of the joint
- Use adapter for smooth lines over transverse joints
- Work in short sections
- Corners - up first then right to left
- Clean Fugi with paper towel when finished

WHAT NOT TO DO
- Don't use tape
- Don't use your finger
- Don't shape silicone in a concave profile
- Don't use water & detergent
- Don't cut the nozzle really small or at 45 degrees
- Don't pull the nozzle along the joint
- Try not to cover all 3 sides of the joint

    As a girl who has never DIY'ed anything in her life, let me say, this video was amazing. As someone else said, who knew a 20-minute video on silicone could be interesting! You really do make it interesting and easy to understand, though. I now feel ready to redo my landlord's awful silicone job. Many thanks, sir!
  • @coltutley
    As a professional builder for over years, This is one of the best explanation videos I have ever seen on the subject. Thank you so much for the time you have put into this and thank you so much for the quality content, you rock!
  • One of the most crystal clear presentations I've ever seen on any topic on YT. The first seven minutes, explicating in meticulous detail how NOT to apply silicone, is invaluable. (I have for years followed as standard practice almost every single one of these DONT's.) I am a professional finish carpenter, with a keen interest of late in improving my caulking game. This video delivered more useful content, accompanied by an incredible degree of logical explanation of underlying principles, than I could have imagined exists. Thank you!
  • @stuartgc8950
    I am not a diy person, have never siliconed anything in my life, followed this video to the letter and am very pleased with the outcome, many thanks.
  • @johndoe4532
    14 years I've been a Floor Layer and I've always hated siliconing. I came across your channel when trying to find the right drill and this came up in my suggested yesterday. I tried this technique today and its so much easier with such a professional finish. For any tradesmen reading, you get a lot of waste as Charlie shows but you just need to add the cost onto the job. Nothing worse than a decent looking vinyl or luxury vinyl tile job and poor sealant finish. Thank you so much for this great demo, and if you haven't already, I would highly recommend subscribing to this awesome channel 😊
  • I like how you explain, why, knowing why is very important. Adults need a reason. Keep up the great training videos.
  • @ComicBookMalc
    Holy cow this is a game changer! I've just done the bathroom in about an hour with no swearing or covering myself/the room/kids/dog/wife in sealer. Thank you
  • Thank you for this tutorial Charlie. I followed your instructions to the nth degree and everything slotted into place. I’m 76 years old and I’ve been a DIY enthusiast for most of my life. I’ve lost count of the number of bathrooms I’ve refurbished and never as Silicone been so uncomplicated and easy to apply. You are amazing! Thank you.
  • @xuscbs
    If I had a company, I'd hire you as the VP of Quality! I love the attention to detail and the power of keen observation! Thank you for taking the time to educate all of us.
  • @Quickblood1
    Genius. I like the idea of not simply explaining why or why not to do something but demonstrating, that really helps.
  • @johnavi
    This honestly makes sense. I always thought the detergent spray method would ruin the caulk that was just applied. Thanks for the lesson.
  • @julessmith5581
    This is a really great, no BS, plain English explanation and demonstration of what I've been doing wrong but didn't really understand 'why'! Just Ordered the Cramer tool - omg they're so good; my 'grouter's-sealant finger' was delighted! Thank you so much for this Charlie; massive shout-out.
  • @spazda_mx5
    I just wanted to thank you for this video, I'd been putting off resiliconing a shower tray that had a slight leak but watching this allowed me to approach the job with a plan and do it correctly.
  • @SteveH51
    I’ve worked in construction for 30 years and what i love about this video is the open mindedness to question supposed tried and tested methods like the fairy liquid in a bottle. Youtube is such a great resource
  • @joemak100
    I like that you go with what you know works with reasoning to back it up.. Many tradesmen are taught the one way and never consider there could be a better technique. Peer pressure/ridicule among onsite colleagues ensure they never try a different method. Keep up the good videos.
  • I know this is an old video but being a pretty naff diy'r, you have inspired me to seal my own bathroom...being 41 and scared to make a mess I watched this, subscribed to your channel and did my bathroom...thanks mate, truly, thank you
  • @chrisammann4041
    What a pleasure to watch - a breath of fresh air. Loads of common sense, and lots of received wisdom challenged clearly and eloquently. Who says a 20 minute video on applying silicone can't be interesting!
  • @chriswherry65
    Brilliant pro video, I've been building and fitting out houses for 40 years and although I thought I was pretty good I got several points from this that I'd never considered! Thanks for spending the time to do a great demo.
  • @daveweston3416
    Nice one Charlie, have been ‘caulking’ for years; watched your vid and purchased the 7 kit, what a game changer, brilliant results. So easy, working in short sections, first caulking job I have ever finished without swearing or going around the house shutting doors. Thanks Charlie, well done mate 👍🏼👍🏼👍🏼
