Is your plumber insisting on using a copper pan for your shower but you remember reading that rubber membranes were not only much more economical, but lasted forever, and did not leak or rust? You can't remember the details, but you want to talk to the plumber and ask questions or insist on using a rubber membrane, but you need your facts.   "ask chris", the do-it-yourself,  and consumer friendly tile installation blog of Tile Excellence, Inc, is written and answered personally by owner Chris Lawson based on his 34 years experience. There are posts all about copper pans vs. rubber membranes.

Doing it yourself? Tile on top of wood? Durock vs. Hardyboard? Is the tile from the designer store necessary, or can he purchase nice tile at a discount store or at Home Depot?

Hired a contractor or tile installation company?  Is three days a long time for installing a backsplash? Is uneven marble floor installation "expected" as you are being told?

At Lowe's or Home Depot and have a question about a product or material? Do you need sanded or unsanded grout? Less expensive thin set, or the more expensive one the salesperson recommended?

Tile Installtion FAQ: Sanded Grout or Un-Sanded Grout?

Tile Installation and Tile Repair 

Most Frequently Asked Questions from Consumers:

  From Newly Forming FAQ on Tile Installation, Tile Repairs & All Things Tile Related:

Many people have asked me over the years which grout to use in their house particular to their tile installation. There is a simple answer to every question. Always use sanded grout whenever possible.

The industry standard states that un-sanded grout be used on grout joints 1/8  or less and sanded grout is used on grout joints 1/8 and larger up to 1/2 inch. So 1/8 inch grout joints can have sanded or unsanded (non sanded) grout applications. The reason sanded grout is always the best option in my opinion and experience is because it is undoubtedly much stronger and longer lasting. The reason being the sand in the grout acts like the gravel in concrete and binds the concrete together and keeps it from cracking. Unsanded grout doesn't have this binding strength and cracks and chips out over the long term and from my experiences doesn't last as long as a sanded grout. Some applications require a un-sanded grout when joints are too small for sanded grout to penetrate or in instances when sanded grout may scratch the installation material. Such materials as Marble, Travertine and soapstone are easily scratched and a sanded grout is not applicable [according to the manufacturer].  But anytime there is a choice between SANDED AND UNSANDED  grout, and sanded can be used, it would be advantageous to use the SANDED GROUT  whenever possible.

Below are pictures of examples installed this past week in Manchester MA of both sanded and sanded grout applications. As well as glass and 'metal mosaic tile that manufacturers recommend be installed with unsanded grout  But  I will explain how and why I used sanded grout for the installation.

Glass tile can be easily scratched when sanded grout is applied with a grout float especially when applied by an unskilled tilesetter. Manufactures recommend using the unsanded grout to install their product. But if sanded grout is applied with the hands and not a hard rubber float sanded grout can be used without scratching the tile giving the installation the long lasting strength that I would prefer in my home .

The advantage of  a UNSANDED  grout is that the finished product has a smooth finished  grout line, clean and smooth to the touch. Sanded grout ends up being rough like sandpaper to the touch.

I always try to bring my customers the highest quality installations at the most economical price , and for DIY and consumer readers with tile questions/concerns here on this blog I have the same philosophy; to bring my readers the information of options for both quality, longevity and economics

This is my opinion only based on years of tile experience. But other tile installation professionals may have different responses based on their training and experiences, so I welcome any to share their thoughts here with my readers. I want this to be a place where people can get help. 

Feel free any time to ask questions and inquires and I will do my best to help anyone in any country regarding any tile situation where my opinion can help you in making the best decision for your job. I realize my opinions are based on my experience, training and perceptions, so other professional tile installers may have different, not necessarily right or wrong just different than mine, so consider it one man's  make to make the best decision about your job  thanks.
