Hi Geoff.

If you've used this in your project, and have a project thread, then your project thread is the place for it.

If you're still doing mock ups and sampling, keep it here for now.

We can always move or separate/merge things later if needed.

Another thing that might help, is to list exactly what you've done rather than saying 'you followed directions to a T'. We all make mistakes and maybe the process of writing it out would help isolate something. Not sayin this is the case, just sayin it might help.

I used 3 bags and two different colors Coffee and Pearl Mixed to the consistency I wanted ( never read the directions). Used in Shower Ceiling, walls and floor also bathroom walls and floor, joints were 1/8 and 3/16. I mixed 7 batches, retained 1" diameter sample from each batch, let set over the weekend then on Monday, one at a time I put sample in a bucket of water. Color and very small amount of sand washed off outside layer of 6 samples, which I think is acceptable, one sample however did loose about 1/16 of an area which was not tightly packed. I went back and checked area where sample came from and found no problems. When taking samples I used the last of what was in bucket rolled in a ball using my hands, however the sample that I would say failed was not tightly packed in the area that washed away.
Conclusion, It would appear that the amount water used in mix (within reason) is not the problem, but how it is applied. I usually pack just as much as I can in joints using Green rubber float.
P.S. Most likely will not use in ceiling any more, it is not quite sticky enough.

Thanks.

Rather than re-type the instructions please see the attached photo for reference. Here’s where I deviated.

1. To mix the package I poured the entire contents into a clean PVC bucket and gently blended it (dry) it with a clean stir stick making sure to consolidate everything.
2. Rather than mixing the complete package I removed 1 pound (as measured on accurate scale) it was put into a smaller clean container
3. I mixed it with 75ml of clean cool water (sorry for the imperial and metric measurements). See instructions.
4. The mixture was mixed by hand in a small container with a margin trowel.
5. Other than that see instructions below – they were followed on the sample board as described in earlier post

The consistency was like loose peanut butter – sorry no slump tests...

Upon drying (now pushing 6 days) the mixture readily washes away in water see photos – not just colour, but quite a bit of sand. The picture shows the effects of wetted fingers slightly rubbed over the surface the left over pancake as described above. The grout ropes between tiles on the sample board does the same.

I tried a second sample mixture, this time making it a little leaner maybe 50ml of water. The consistency was like thick peanut butter. This doesn’t wash away as bad as the first sample, but still does. I guess I'm not sure what acceptable is.

Does anyone see any user error here - before I throw in the towel and try a different product.

Use Permacolor from Laticrete and your problems will be solved. I just did a huge shower with it and I have to say they have made it even better to use.

Looking at Kevin's post above, what is considered an exceptable amount of colour and sand coming off?

(Can't find laticrete products around here)

Any of these products can be shipped. To your door, if needed.

Reply to Geoff's question what is acceptable, Color wash off discolored but could still see bottom of bucket, water was 3" or 76.2 mm deep in 5 gal or 18.927 Liters bucket and the sample was a ball rolled in hands like you would roll a meatball, diameter of 2" or 50.8 mm
The sand that washed off was half of a teaspoon.
Geoff why is your sample tapered on the ends?

It's tapered as it is a portion of a pancake I made maybe from two meatballs. Once dry, I broke in half to keep a sample 'unmolested'. A smaller piece in a glass of water discoloured the water so much you could not see the sample or through the glass to the other side. The amount of sand I don't know. I had the sand sitting on the counter to dry and Mrs. Geoff unknowingly threw it out. It was a lot from a small sample.

On my second sample, it was quite a bit better, but not what I would say was very easy to spread. Again like thick peanut butter.

I called the supplier and a TEC rep has apparently been contacted. It has been suggested you mix it to the consistency of wet beach sand. That would seem too stiff to me to spread easily. Not a lot of fun on a wall, I am sure and would result in a ton on the floor.

I would suggest to get it to that consistency, you would not use the amount of water as indicated in the instructions?? So maybe that is my issue - too much water in the first attempt.

Hi:

The one pound tests were mixed in small clean continers with a margin trowel.

Geoff, How much thinset did you add to (water was 3" or 76.2 mm deep in 5 gal or 18.927 Liters bucket ) to get mix?

Ratios as per instructions.

One pound of grout and 75ml of water. The instructions say 25 pounds of grout and 1.89 litres of water. (see post 48 above).


Sorry:
75ml is about 1/3 of a cup. Roughly.
1.89l equals 1890ml

3" of water seems like a lot to me.

At the rate you mentioned = 75" of water to 1 -- 25# bag of grout

I usually place approximately 1 to 1.5" of water in a 2 gal bucket and add 4 to 5 scoups of grout then adjust to obtain the right mixture.

Thanks Hammy;

Sorry. I think I have been confusing. Chalk it up to growing up when we were converting from imperial measurements to metrc. I readily use both.

I made up one pound of grout for a test. I mixed that with about 1/3 of a cup of water (which is 75ml (ml is millilitres)).

I am pretty sure about my math.

Geoff
