Welcome to Home Improvement Stack Exchange

Home Improvement is a question and answer site for contractors and serious DIYers. The core of this site is around parts of your home that are typically included when you buy or sell it, the structure, utilities, and major appliances.

It's built and run by you as part of the Stack Exchange network of Q&A sites. With your help, we're working together to build a library of detailed answers to every question about home improvement.

We're a little bit different from other sites. Here's how:


Ask questions, get answers, no distractions

This site is all about getting answers. It's not a discussion forum. There's no chit-chat.

Just questions...

...and answers.

up vote

Good answers are voted up and rise to the top.

The best answers show up first so that they are always easy to find.

accept

The person who asked can mark one answer as "accepted".

Accepting doesn't mean it's the best answer, it just means that it worked for the person who asked.

grouting or caulking? bottom of tiled wall at tub rim

up vote 14 down vote favorite

At the tiled wall surrounding the tub, at the bottom of the tiles where the tiles end and intersect the tub rim, should it be grouted ( epoxy grout)? or leave it open and caulk with silicone caulking? Please advise!

Caulking always! Fill the tub 50% with water and caulk it. Allow the caulking to dry then drain the tub. If you caulk with no water in the tub poly, fiberglass and composite tubs stretch and tear the caulk when filled. Cast tubs are usually solid enough to not make a difference.

I always use a color match caulk on any right angle or edge of tile,silicone is not a good idea for too many reasons.


Get answers to practical, detailed questions

Focus on questions about an actual problem you have faced. Include details about what you have tried and exactly what you are trying to do.

Ask about...

  • Questions you would typically ask a home contractor.
  • Which tools, materials, and best practices for home improvement task.
  • Identifying the source or cause of a problem within your home.
  • National building codes (of any country).
  • Installation, maintenance, and repair of major appliances.
  • Carpentry and woodworking.

Not all questions work well in our format. Avoid questions that are primarily opinion-based, or that are likely to generate discussion rather than answers.

Questions that need improvement may be closed until someone fixes them.

Don't ask about...

  • Anything not directly related to home improvement
  • Hobby projects, decorating advice or landscaping.
  • The cost of a job or the price of tools as these will vary between locations and over time.
  • Questions that are primarily opinion-based
  • Questions with too many possible answers or that would require an extremely long answer

Tags make it easy to find interesting questions

All questions are tagged with their subject areas. Each can have up to 5 tags, since a question might be related to several subjects.

Click any tag to see a list of questions with that tag, or go to the tag list to browse for topics that interest you.

When they are water based and clean a wet finger is a great tool. I will only use tub &tile calking as it has mold inhibitors. The trick is getting the old stuff cleaned out first. With new tub surrounds I will use a 400 grit sandpaper inside the joint then wipe it down and calk the small scratches inside help the sealant hold, some of these surrounds look great because they have a slight coat of wax the sealer fills the void but falls out later, I once had a home owner swear I should be able to purchase this seal that fell out in one piece. - Ed Beal Sep 30 at 0:34
