Praying to the Cement Gods...
Please let my mixture cure to a beautiful, hard, water resistant thing of beauty.
After reading all sorts of possible mixtures and additives and this, and that, and being generally overwhelmed.
Here is what I went with.
5 parts sand
1.5 parts portland cement
Dry mixed together.
Then added sparingly...
A latex bonding additive (mixed with 1/2 water).
Worked it until it was saturated but clumpled in my hand and my hand pulled away clean.
I used this in a test area outdoors to fill some cracks and level out some uneven areas.
If it cures nice (fingers crossed) then I will attempt to use this mixture on the inside slab and as a form for a threshold.
Have no idea what your goal is but that mixture isn't likely to last if thin (for a threshold) and being walked on.
What are you trying to do exactly?:)
Why does this have to be so complicated?
You are probably right. I just did some test areas outside. Some cracks and spots here and there to see how it would cure.
I agree that it looks a little sandy and like it could wash/erode away.
I also just mixed some pure portland cement with water and put that in some places. That comes out more creamy. I'm not sure how it will cure though.
What I want to do:
I have some gaps where the slab meets a concrete retaining wall that I would like to fill. They are not big gaps.
There is an odd brick column corner that I would like to smooth and shape the base of.
Then there is the threshold (s) issue.
I have no idea about the one that rests on a 2x8. I can't figure it out. No standard threshold fits the depth of the sill board and apparently the 3/4" depth is not enough to accomadate tile, barriers, 2 mortar beds and whatever else goes into tiling.
There is another door that opens over the slab. I thought a threshold could be formed out of cement and tiled over in that area.
Yet, that won't work if my mixture is too weak.
Thanks for your response. Perhaps I should give up. I even called a pro, but the job is too small and he didn't want to do it.
It is very frustrating.
