Technical ?'s re: concrete & breaking up tiles for small patio

18 years ago

Below are photos of 1) a small patio I'm wrestling with how to fill in, and 2) some 16" tiles I scrounged & am considering using. My ideas change daily as I discover new options. Today's discovery is the idea of simply filling in the shape with concrete & using ferrous sulphate to stain it. Yesterday's was to break up the tiles into more organic shapes & use them mosaic-style on top of decomposed granite, adding pebbles in spaces between. Now I'm wondering about filling in with concrete & setting tile pieces into the concrete, & then using ferrous sulphate to color the concrete between the tile pieces. [This idea sounds like a more stable surface, since the tile pieces might be apt to crack more easily on DC than if set in concrete.]

Each option raises technical questions I could use help with.

1. What makes concrete come out smooth on top? Is it related to the type of concrete used or a process done to it or both? Staining w/ferrous sulphate works best on smooth surfaces, so whether I just use concrete for the whole thing, or as something to set the tile into, I need it smooth.

2. When I go to the supply store, there are several types of concrete. Is it all gray, or is some whiter or lighter gray? This would relate to the color I get after applying FeS.

3. Regarding breaking up the tiles, I have a chisel, tile nippers and a mallet. I'm wondering if there are techniques or tips for breaking the stuff up into shapes I want. I'm aiming for more pieces with rounded edges, especially for the roundish borders of the patio. Do I just hammer at it & hope for the best, and then use the nippers to take off corners? This particular tile seems quite layered & almost flaky.

All answers, input & brainstorming will be appreciated.

Thanks,

Karen

Karen you win the 'most tenacious Creative persons award ! '

you got spunk !

Q - What makes concrete come out smooth on top ?
A - It is the way one floats the finish. - mix it up, dump it into your form, and then level it out ( partial floating ) with a 2 x 4, - wiggling it back and forth. as you do this the concrete will smooth out . you can then use a variety of trowels to float the finish.

Q-... there are several types of concrete. Is it all gray, or is some whiter or lighter gray? This would relate to the color I get after applying FeS.
A. - If you buy your concrete in bags it is all one standard color grey. You can mix in dry colorant into the dry mix. - Shamrock Supply in San Rafael has all of this for you .
The application of iron sulfate to the colored concrete will definately change the color of the concrete.

Q. -...techniques or tips for breaking the stuff up into shapes ?
A. - Lots of different types of techniques for breaking up your travertine tile.
The best tool for your money is a $ 45.oo Angle Grinder with a diamond blade .
I have a Ryobi 4.5 Angle Grinder that was given to me as a gift over 15 years ago. I LOVE IT and have used it on all kinds of projects over the years.

You don't have to cut all the way thru the tile, you can simply score it and then snip off the corners . afterwards you can round them off with the saw again.

If you're interested come on over to my house in Novato and I'll give you a demo.
We are also working on a project in Kentwoodlands and you could see the guys doing some really interesting stone work .

you got my email. give me a buzz and I'll give you the nickle tour of my garden at the same time

Pouring concrete patio against basement windows

It is the screen slider that threw me off. I first thought it was all a slider. When you said it was french doors, It appeared to be on the outside of the door frame which would not open inward and the handle is on the left. So from the outside, it is effectively a slider on the left side as I thought. The part that is no good is the fact that it puts the user walking out along the face of the house wall whether it is a french door, slider, dutch door, or conventional pass door. That is compounded by the cellar window. If budget is not a big issue, I'd change the door. It would be an issue for me, so I don't blame you for sticking to it (but it is poor building design). The sensible solution, barring changes to the door, is to build a wood landing the full width of the wall with the door on it. Then have the steps coming down off of that onto a conventional patio layout away from the house. There are many good ways to do that. Put in two standard metal window wells so that you can fill to proper grade for your slab. Keep a planting bed between the slab and the house where there is no landing. You may as well have the concrete guy waste his extra mix in the area that will be covered by the landing (what they call a dust cover). That will keep burrowing varmints from taking up residence (see that that also pitches the water away). The dust cover does not need any fancy finish, so should not cost very much at all. As long as you resign the idea of keeping both windows open to daylight this is a very standard wood frame step and patio.

Converting enclosed concrete patio into zen garden
Q

"I'd like to turn into an enclosed zen garden..." What do you mean by "enclosed"? "... with gravel or flagstones ..." added how? Do you mean place on top of the existing slab? There is NO possibility of raising the slab grade. You don't even have room to add tile. Given the utility doors and lack of a patio door, this looks like a strictly utilitarian area. Wouldn't you be making sacrifices of utility in order to convert this to a zen garden? The only realistic solution for dressing it up is to add a few movable planters. You could also kill the weeds in the crack and paint the slab with concrete paint if you want an improved surface appearance.

What color will help break up all this brown?
Q

Good old Navajo White! So here's my take--I personally don't like the variegated tiles on the right, I think they're overused. (I seem to see them on walls a lot in awkward foreclosure remodels. They're better on floors, but still....) For paint, what about going with something slightly browner than the Nav White, but not as dark/yellow as your sample above? Then you can still paint the outline of your door a bright white for contrast. (Remember to paint the front bottom part of the doorframe too, so it doesn't look like the door is floating in space.) Back to tile, I like the bottom middle one, or the small square on the left above it. The samples on the far left are too gray to coordinate well with your brown/cream.

Concrete patio sinking, NEED advice on remedy
Q

They are manufactured blocks/tiles, not poured in place. You might call them paving blocks or patio tiles. They look quite worn & weathered, meaning that it might not make sense to spend money on resetting them, only to have an old, near-the-end-of-its-life patio when you're finished. It would make more sense to reset them as a DIY project, since it wouldn't cost much. Or, to suffer along with what you have while saving money for a new patio. The picture does not show much of the surroundings, but the yard looks quite flat, which would make it difficult to capture water at the patio edge and then run it underground by gravity to a different location. A stop-gap measure could be to install an underground cavity -- a literal French drain -- but that's an iffy proposition (and a fair amount of work.) You don't have any way of measuring the actual volume of storm water that would come to the outer edge of the patio. If the underground cavity was a little shy of handling the capacity, the patio would still flood. It would drain away and dry up quicker, but that might not be enough to justify the effort. What it would cost to have it reset by professionals would vary, depending on your location and its market for this type work.
