Why Seal Around Sink?
One of the most notable problems with both kitchen and bathroom sinks is the water that builds around them. This eventually leads to soap foam and mold on the rims of the sinks, both on top and on the bottom. Constant cleaning provides a solution. However, you have so many other places to clean and so many other things to do. Although there are relatively few sinks that come integrated or molded into one unit of both the sink and the countertop, most sinks in bathrooms and kitchens come as separate units from the countertop. This means that they must be installed.
During the installation process, kitchen and bathroom sinks are professionally sealed to the countertops. This makes the sinks stay in their place and makes the sink edges watertight. This prevents water from seeping beneath the sink edges which would hence lead to damage to the areas beneath the counter. Over time and as the caulk or sink sealant used to make the seal shrinks, dries out and cracks, the seal wears out and would therefore need a replacement.
Getting to know how to seal around sink to fit well with the countertop and using a high-quality kitchen sink sealant, or sealing your sink drain with silicone, will ensure that your sink remains in superb condition. This will also prevent future sink problems. In order to prevent water and other debris from seeping or entering through the gaps, you need to use high-quality and waterproof sink sealant to seal around sinks. Do you want to prevent water and mold damages in your bathroom or kitchen? Then you need to seal around your bathroom and kitchen sinks.
What Leads to Leaks?
Whether you contracted a professional to install your sink or you did it yourself, it is not uncommon for your sink to develop leaks within days, weeks, or months after installation. When you notice these leaks, know they may be caused by one or more of these possible causes;
- Using the wrong sink sealant. Using the wrong kitchen, bathroom sink sealant or undermount kitchen sink sealant is a sure way of creating sink problems. Always use pure, 100% silicone sink sealants. This is because silicone sealants are flexible and contain powerful adhesive properties.
- Problematic or poorly installed countertop bottom. The area at which the bottom contacts the sink should be well prepared. Before caulking, ensure that you have used denatured alcohol to clean off any debris that may interfere with the installation process.
- Failure to properly secure the clamps. You may have cleaned the sink bottom properly but failed to make the installation secure enough. Always make sure that the epoxy and the clamps used are tight enough so the caulk will not quickly pull off.
How to Seal Around Sink
How to seal around sink may sound daunting but it is in fact easy. You can perfectly learn how to replace silicone around sink, how to seal kitchen sink to granite, and even caulking around bathroom sink all by reading through the following simple steps.
- Make sure the clamps are holding the sink bottom to the countertop securely. You can do this by crawling under the sink and checking the clamps. If they are loose, tighten them up.
- Apply undermount sink sealant. Apply silicone sealant around the seam around sink. This will take care of any leaking problems that may have been present.
- Re-caulk. If you have made sure that the clamps are secure and tight, you can try to re-caulk to see whether the problem still exists.
However, you need to note that the best solution to sealing bathroom sink to countertop is to remove the sink entirely and reseal it to the countertop. And without wasting any time, here is how to seal around sink in simple steps;
- Turn off the water at the mains.
- Remove the pipes and other plumbing materials.
- Unclamp the sink from the countertop.
- Pull the sink away from the countertop.
- Scrape or clean off as much caulk as you can. Use a sharp cutting tool or a putty knife to remove the old sink sealant. You can also use a silicone remover.
- Use denatured alcohol to thoroughly clean the surfaces. Make sure to avoid using water in the cleaning process. If you do not have denatured alcohol, you can use a regular house cleaning agent. Spray a paper towel or a piece of cloth with a household cleaner and use it to clean the surfaces. After doing this, clean the surfaces again using a bleaching agent and then leave the surfaces to dry.
- Prepare and apply a thin globule of pure and 100% silicone sealant to the top lip of the sink. Put the cartridge in the silicone sealant gun then cut the nozzle to a good width at the tip. Make sure the sealant flow is okay by testing it on a scrap surface. After making sure the surfaces are completely dry, apply the sealant uniformly around the sink. Also, make sure that you smoothened the caulk around the sink and the countertop by using a tooling gadget.
- Quickly re-install the sink before the silicone cures. Avoid exposing the surfaces or the newly applied sealant to water until everything dries up.
- Clamp the sink tightly into place. Make sure the clamps are tight enough so that there is no possibility of leaking.
- Wipe off any sealant that may have seeped through on the sides of the sink. Remove excess sealant or any that overflowed to other surfaces. Wipe off with a clean rag or a good silicone sealant remover.
