How to Fix a Cracked Sink

A cracked sink can be so disgusting. Your floor won’t look neat and presentable when your sink keeps on dropping water to it. The water that drops may cause your floor to crack or even the tiles to break. Apart from splashing water to your house, it may also cause an injury to you. When it cracks, it leaves behind sharp edges that can cut someone’s hand easily. Another negative effect of a cracked sink is that it makes the house look untidy. One of the best remedies is to fix the cracked sink. This article is going to reveal how to do it. Read on and find out more.

Steps to follow to fix a cracked sink

Rid your sink of water

Empty the sink of all the water. When the water has been fully drained, leave it to dry completely. If you want to fix it instantly, you can dry it using a handheld dryer. If you try to fix it when wet or moist, it won’t bond together. In the case that it doesn’t bond properly, it will crack again without hesitation. The adhesive that is used to hold the cracked parts together won’t be able to hold on and dry properly.

Fix the crack

After drying properly, then it is time to fix the crack. Take the epoxy adhesive and fill it in the crack. Do it slowly, carefully and smoothly. Use a thin stick such as a matchstick to do the filling. This will enable the adhesive to get in properly through the crack. The matchstick will enable the adhesive to go to where it is only needed without touching where it is not required. You have to be more careful to avoid spreading the adhesive to there it is not cracked.

Give time the epoxy to dry

After filling the crack with the epoxy adhesive, give it sufficient time to dry up completely. The best recommended time for it to dry completely is 24 hours. If you went it before the 24 hours elapses, the epoxy won’t dry well and the crack won’t hold. The crack may grow wider leading to a total breakdown in the future. When the adhesive epoxy is fully dried up, it can withstand wetness.

Paint the epoxy

When fully dried up, you will need to proceed to the next step. Get the paint with the color similar to your sink. Apply the paint to the dried epoxy. The paint will make your sink look new again. The good thing about this paint is that it is water-resistant. It guards water against sipping into the adhesive. Your sink will look uniform too as there will be no difference in coloring even after the repairs.

Let the paint dry

As you did with the adhesive, you also got to let the paint dry up properly. Do not let the water come into contact with the wet paint. This is because it will interrupt the drying process. Do not touch it with your hand too. It will distort the uniformity.

What are the main causes of the sink to crack?

Cracking can be caused by a wide range of factors such as:

  • Extreme changes in temperature. When it becomes so hot, the particles may expand causing it to crack. When it becomes too cold, the contraction of particles may cause it to crack too.
  • If you dropped something like a jar, it may end up breaking it.
  • An old sink can crack easily even on its own, without any external pressure causing it.
  • When it is not properly fixed when installing.
  • If roughly transported from the purchasing store to where it is to be installed. This may cause fault lines to develop from within the sink itself. With time, these fault lines will develop into full-blown cracks.
  • Poor structural soundness during manufacture.


A sink can be a very delicate thing. Always exercise care when using it. Be careful not to drop hard items to it. Keep monitoring the health of the sink. When you notice a crack, move with speed to fix it. If you don’t, it will eventually break into pieces. Always get a qualified person to do the fixing for you.
