grout discoloration issues/bad application

Hello to all,

We bought our house in 2008 and had interior exterior painting done. What we didn't know the contractor was going to do was put a "coat of something" on about 1700 sq ft of 18 x18 tile, and the grout. The original bad application led to a discoloration type haze that we had to remove...since then, we've had to use those small rollers w an off white color to keep the grout clean.

What we want to do is clean all of the tile and deep clean the grout, then after fully dried, seal the grout so it does not oxidize so fast and discolor as in pic #1, Am I on the right track or do you recommend another route?

If you have any questions, pls let me know. Thank you in-advance.

Hi Tom,

A sealer won't prevent the grout from getting dirty, especially if it's sanded grout. It's like trying to clean sand paper -- sealer or no sealer.

You could clean the grout and then use a grout stain over the entire floor. Make it a lot darker.
