The product is very good but the quantity is very less

It's very useful for cracks & unwanted gap on walls . this is a foam based formula which is easy to use

Phone quality is good but the outlet tube once is used can’t use more time

After opening foam, the can will start leaking. The valve of the can does not close properly and will keep leaking foam. It is just a waste of money. Avoid buying it.

I recently used Sika Boom for sealing gaps, and I’m thoroughly impressed! The foam expands well, fills gaps effectively, and provides strong insulation. It adheres securely to different surfaces and dries to a firm, durable finish.The application is easy with the precise nozzle, allowing controlled dispensing without excessive mess. It also cures relatively fast, making projects quicker to complete.
