Regrouting pool tiles for better appearance

Postby PoolShark » Sun 25 Oct, 2009 16:59

Hi all

I want to drain the pool now it's Autumn in Spain and regrout the existing tiles to give a fresher, cleaner look. Can anyone tell me the correct preparation method please before I start and also the best way to apply the grout. I will be doing this on my own and my pool is a rectangle and measures 8 x 4 metres.

Regrouting can be tricky. We hand scrape as much of the grout as possible and then give an acid wash (concentrated). The results still tend to vary and we have new grouting lifting after only a few months in some cases.

Not only tricky, but also tiring and lot of it.
It is so much more of it compared with bottom of your shower stall!
You may want look into buying a Dremmel tool.
High speed tiny drill motor with masonry bits that in angle will remove needed depth of a stuborn grout.
The tool is not cheap, but lot faster and easier to guide than a grout scraper.
As your hand gets tired you will tend to slip out of the line onto the tile surface, scratching the glaze of the tile. It is next to imposible to avoid it, every once a while.
Than comes the need of building a scaffold for the deep part of the pool.
You actualy need better access to the tile than for re-tiling because you need to be closer to handle tool properly.
Good luck and remember, that everything has it's end.
Even when it looks like it never does! :wink:

Hi poolshark, I just find an article that I think can help you with re-grouting your pool tiles.


The first thing you need to do is determine whether you have sanded or non-sanded grout. This is important because regrouting should only be done to non-sanded grout joints.

It is important that you remove at least 1/16 of an inch of grout for the new grout to embed itself in. If you do not, it will surely flake off the next time you clean.

Important tools to use to make the job easier:

First, for the grout removal process you will need:

* First choice: Roto Zip with a diamond tile cutting blade and attachment (This tool is for an advance user and should only be used by someone who is not afraid of the speed in which it spins. This tool will yield the best results for all field areas but it an also cause damage if not handled properly.
* Second choice: Fein Multimaster with a diamond cutter not carbide. (This tool is for an advance and novice user and is the safest tool for removal but takes a little longer. It has alot of other uses also and in my opinion is a great investment)
* Dremel with tile cutting bit (This tool is for edges, corners and touch-ups)
* Wet or Dry Vac
* Razor Scraper for removing old caulking

These are the most important tools for the removal process and will yield the best results for both minor removal and removal on a large scale. There are other hand tools you can use but are only good for very small jobs.

Next, you will need tools for the grouting process:

* 2 Buckets (One for mixing grout and one for water)
* Grout Float
* Margin Trowel for mixing
* Grout Sponge
* Terry Towels for cleaning, final dusting and sealing

Now you need the supplies to clean and prepare the joints for the new grout and seal the new grout.

* Phosphoric Acid Cleaner
* 511 Impregnating Sealer
* Chemical resistant spray bottle
* Scrub Brush
*3M Heavy Duty scrub pads

You can clink the link below to know the procedure. Hope this helps.

What do you use to seal the grout? Our pool company said not to seal the grout around our salt pool. :eh:

If grout is white "the good epoxy grout", no need to seal. If grout is sanded tile grout it should be sealed. Deck and coping or cantilever should be sealed with a good quality sealant. These are the water based ones that we seal pavers and flagstone with.

We are replastering our pool and adding a mosaic design on the bottom. What kind of grout do I need to use? I have been told that I can use regular sanded grout.
