silicone

A silicone or polysiloxane is a polymer made up of siloxane (−R2Si−O−SiR2−, where R = organic group). They are typically colorless oils or rubber-like substances. Silicones are used in sealants, adhesives, lubricants, medicine, cooking utensils, thermal insulation, and electrical insulation. Some common forms include silicone oil, silicone grease, silicone rubber, silicone resin, and silicone caulk.

    Can I use silicon to seal grout?

    The grout in my shower is constantly needing mould & mildew treatment, and is generally looking tired. I am considering removing and replacing any damaged sections of grout, then applying silicone over all the grout lines to seal them. Is this ok to do? Very grateful for any advice.

    Silicone between tiles and bath, I didn't bevel it, bad idea?

    I finished tiling my bathroom and used BAL silicone matching the grout along the 4mm gap between the tiles and bathtub, I used a Fugi tool with 90 degree edge as I thought it looked nicer and was easier to tool than using the curved edge. Is this a bad idea, I assume water will sit closely along...

    Replace glass tile - which adhesive to use?

    Dear all, as a homeowner, I have had to hack off a glass tile which is backpainted from a wet room.

    Fugi Kit for silicone and tiles.

    I have tiled down a wall to a kitchen worktop and want to silicone the join where the cut tile meets the worktop surface. I laid a bead of silicone and used a Fugi Kit with the "bridge" but still get indentations at the grout join between tiles. Any suggestions would be appreciated.
