What is the normal practice for tile setters sealing grout? One of the guys I work with just had a new house built and he said the tile guys he used don't seal the grout? Is that common practice, or do most companies finish by sealing?
It can vary by parts of the country and neighborhoods depending what most contractors do and what customers want to pay for. But in most cases homeowners would rather do the sealing themselves and not pay someone else to do what is normally a simple task. Also, sealing usually can't be done until the grout has cured at least 2-3 days and after the final cleaning. Wouldn't make sense for most people to pay a tile setter for something simple like that.
In some cases sealing might be necessary to do before grouting, with certain porous natural stone tiles, and usually needs more sealer after installation is complete too. So it depends on the situation.
For some customers who would rather not get on their knees or get their hands dirty, we can include both sealing and final grout film removal too.
