How do I properly seal a pedestal sink to the wall?
Hi I am going to install a pedestal sink in my bathroom, however, aside from the screws that anchor the sink to the wall, is there any other sealant/caulk/glue I should buy that will ensure that the sink adheres properly to the wall so that it is firm and rigid (so it doesn’t wobble while turning on the faucet etc)?
Silicon sealant – but the fixtures should hold it solid really; the sealant only stops water going where it shouldn’t!
If you position it correctly you shouldn’t have a problem. However that was not your question. The product, "liquid nails" is an adhesive that you would have to pull the wall out to remove it. If you don’t want your sink to move, I suggest this product. There are other adhesives that are effective, but not as much as this one. Bear in mind that once this sets, it will not move. If you choose to change it in the future, it will take the drywall with it.
If secured properly it will not move.To fill small gap between wall and basin use white mastic in a mastic gun then wipe lightly with damp sponge.
The anchors should hold the bowl firmly to the wall. Use silicone caulk around the edge to prevent water from going between the bowl and wall if splashed.
