Added to the above the caulk holds the sink in place, seals between the sink and the counter top preventing moisture from getting into the particle board the counter top is made from. If the particle board gets wet it will swell and bulge further breaking the seal. If it is a marble top any moisture will get into the cabinet Which is usually made from particle board and cause damage, swelling and mold! It also provides a nice clean joint between the sink and the top.

Silicone is waterproof and mould and mildew proof, it is usually only under ceramic sinks and is used to attach it to a granite, marble, acrylic or laminate surface.

See answer above and add to it that it helps the two surfaces stay where you want them to be.
My answers are short and sweet. Common sense mostly. If you are trying to get something for nothing...Don't waste my time! Remember if something sounds to good to be true that it usually is. I've spent many years of my life trying to cheat the system and was pretty good at it. This all changed when I discovered that people were doing the same thing to me. What comes around, goes around. Karma! Now I assist people in making win-win deals...that are legit!

Silicone-based caulk is often applied to the underside of bathroom sinks in order for the caulk to seal the gap between the sink and the wall, preventing moisture from getting underneath the sink.

My tub is plastered into the wall with caulking. Recently, I have noticed that the caulking is dissapating and loosening up the tub. Fortunately, I have not see a change in my water flow. I want to


Unfortunately this is usually caused by a leak and the drywall is wet , and or the tub is sinking due to water damage to floor. If the drywall is solid then use a utility knife to remove old caulk, then after area is clean apply silicone caulk around the tub. apply neatly but with plenty enough to fill the void. I then spray a dish soap an water mixture on the calk then remove excess by pressing thumb down and sliding it long caulking. This presses it into the gap and also removes excess, which leaves you a neatly caulked tub.

Remove bathroom sink flange


Turn off the water valves at the back of the sink and place a bucket underneath the drain to catch any water that may run out.
2 Loosen the nuts that hold together the drain tailpiece and the P-trap with a wrench. Disconnect the the two pieces.
3 Unscrew the drain tailpiece from the drain flange. Depending on how the drain flange is held in place, you may need to hold it down firmly as you twist the tailpiece below. Remove the tailpiece and set it aside.
4 Remove the old drain flange. It may come straight out after the tailpiece is removed, or it may be held in place with putty or silicone. If it is held in place tightly, grasp the edge with a pair of pliers and pull until it comes free.
5 Wipe down the sink area that was underneath the old flange. If the metal was discoloring or rusting, clean the porcelain well and dry it to keep the new flange clean.
6 Apply a thin bead of silicone caulk to the underside of the new flange. Push the new flange into the drain hole in the sink.
7 Push the drain tailpiece back up into the sink's drain from below and screw it into the flange tightly. Use a wrench to tighten it up securely.
8 Reconnect the P-trap to the tailpiece and tighten the nuts that hold it in place. Turn on the water supply to the sink and run water through the pipes to ensure everything is securely fastened.

When installing do you silicone each piece for example the faucet , the soap dispenser ,the sprayer , and the tap


Hi seawitch678,

If you have a granite or stone countertop/sink, use silicone as plumber's putty will stain the stone. Plumber's putty is petroleum based so it will not adhere to stone. Normally you should use what the manufacturer recommends and where they recommend. When installing a faucet, put either around the base of any piece that goes through the countertop.

Hope this helps. If it does, I'd appreciate your vote. Thanks,

Difference between black basket strainer 900 and regular strainer.also i want white. are there different sizes or universal.


Unless you have a special purpose sink all basket strainers are standard size. You should be able to use strainer from any manufacturer that has the color that you want. If you are doing this yourself make sure you use rubber gasket and fiber friction ring. These go on the underside of sink in between sink bottom and retaing nut. I would recommend you use a small amount of pure silicone caulking in between flange of strainer and sink surface. Be ready to wipe off excess caulking as soon as you get retaing nut snug as it starts to cure in about ten mins. I use paper towels and wipe till its clean. Hope this helps. Thanks

How do you remove uncured silicone fron the silgranit sink?


Well this must be coming in late. I'm sure the stuff has cured by now. I tell everybody, silicone is for one thing, FISH TANKS!!! Do not use it for anything else. You will have to razor the excess off now, it will still leave a film on the surface. The proper stuff for your sink would have been siliconized acrylic latex caulk, It is cleanable with water, molds right in nice, seals, super strong, waterproof. That is what we use. We have stuck houses together with the stuff. Don't know if they are still standing.
Granite guys use silicone to stick their tops on and caulk up under the counter, but you don't see their joints. That is OK, They could use any caulk but they like the adhesive bond of the silicone. Hope this helps.

How do we install the clips on the bottom of a top mount sink


The clip with the screw together, with the screw head down and the claw up, go into the channel on the underside of the sink, they go through a slot in the channel then slide to fit about 3 or 4 on each side. Tighten up the screw and it should pull the sink down and clamp onto the wood under side of the counter top. Put a bead of siliconized latex caulk around the edge of the sink before dropping it in, DO NOT USE SILICONE!!!, then with a wet rag, clean it off what gurks out. You should be all set.

Sink Basket leaks and cant be removed cause of silicon adhesive


steady pressure from under the underside of the sink should cause the silicone to flex and eventually release.

You might also try some caulking remover available ot hardware stores. It's a product that comes in a tube and eases the removal of caulking products.

Be sure to look at the label for cautions and materials that it is safe to use it on.

Installing an undermount sink in case it need to be removed


under mount sinks are 'glued' to the underside of the granite countertop using clear silicone caulking. Clean both surfaces really good with alcohol or acetone (or even disc brake cleaner, apply caulking to bowl flange and position bowl up to underside of counter. Temporarily block in place and let cure for 48 hours. To remove bowl later, use a thin cutting blade like a hacksaw blade to slice through the caulking line. It helps if you don't squish all the caulking from between the bowl and the counter so that you can just get the hackwas blade in there in the future.
