How to Prevent Your Sink From Cracking and Chipping

Although the process of fixing a cracked porcelain sink is relatively straightforward, it’s not a project you want to do more than once.

How can you prevent cracks and chips?

Avoid extreme temperature fluctuations. If you’ve been running hot water in your sink, abruptly switching to cold will shock the surface area and could cause a stress crack.

If your drain is clogged, use a drain cleaner product. Don’t pour boiling water down the drain as the spill-over could cause unnecessary stress on the porcelain and lead to cracks.

Keep the soap dispenser, hairdryer, and any other heavy objects a safe distance away from your sink.

If you are remodeling or moving heavy items, put a protective barrier such as thick cloth around your sink to protect it from bumps and scratches.

This DIY porcelain repair kit will leave you feeling like a home improvement specialist and save you money in the process.
