how to use SLC?

I have to level my floor with SLC. Do I fill whole surface with SLC covering even the highest spot or just bring the lower area up to the highest?

Thanks

You really want to have at least a little over the high spot. The stuff is not like water, so will try to hold together and bridge a high point, keeping it high. Only if you have enough to exceed that high point does it flow well to level. It's actually easier if it is more than just a bit deeper than that minimum. If you're doing this over a wooden subfloor, you'll also usually need lath, and you want that covered entirely as well, thus the depth.

A gauge rake makes things easier, and a porcupine roller can help, but you can live without that. A flat blade can help to smooth any ridges. When pouring, you have to keep a wet edge, and, you do not have a lot of time, so help is often prudent, if not required so someone can be mixing the next batch while you're working with the first. You need the right mixing paddle, or you'll be mixing air into it, and creating pinholes as they pop.

Mike, a lot of that depends upon what you're pouring the SLC over. Many manufacturers require reinforcing lath and a minimum thickness over wood framed floors.

I have to add that I am talking about a concrete floor.

Over a SOG, you don't have a minimum thickness issue, but slc will still try to create a cap over a high point. You can run it to a feather edge, but you'd want to pick up some tools to do it. Most only have a working time of about 10-minutes, so you need to get the stuff mixed and placed quite quickly which works best with help. You still must ensure that the slab will absorb water if you sprinkle some on for it to work, then, you need to use the appropriate primer and cover it within the stated time (varies by brand and type, sometimes a lot).

What's the best paddle for SLC?

Paddles designed for slc look like an oversized kitchen beater - often an egg-shaped thing with round wires. Paddles for thinset will tend to be smaller, add too much air. When mixing, do not lift up and down breaking the surface. Use a scraper like you were mixing up cake batter to get the dry stuff off the sides and fully mixed. Unless you have a fairly hefty drill motor, you may either burn it out, or not mix things properly. Note that the timer starts as soon as the powder hits the water...if you can, use cold water, the colder the better, it will give you an extra minute or more before things start to cure. And, get the stuff out of the bucket...it will get hotter quicker in a large mass - spreading it out gives you a little more working time.

The stuff isn't as dramatic as hydraulic cement, but it goes from liquid to stiff solid then hard quite quickly once it reaches a certain point and there's no going back!

Laundry room floor

I have a small (5'x5') laundry room floor to tile. Substrate is concrete. In few days I will pour the SLC to remove some hills and then Ditra and tiles.
Since washing machine is producing a lot of vibration, what tin-set to use between ditra and concrete and ditra/tiles? Tiles are 8"x8" porcelain. I understand that I have to use an unmodified tin-set. Stores around me carry Mapei and Ardex brands.
My main concern is to use a tin-set that will last to vibrations.

Thank you.

Mike, an unmodified thinset mortar will say on the bag that it meets ANSI A118.1 when mixed with water. Look for that specification.

You want a good quality mortar, not the manufacturer's, any manufacturer's, bottom line product.

Mapei has a couple I'm aware of:

UNCOUPLING MEMBRANE MORTAR:http://www.mapei.com/public/US/produ...rtar_EN_lr.pdf
KERABOND T: http://www.mapei.com/public/US/produ...T_EN_LoRes.pdf

I'm not sufficiently trained to give you recommendations on the Ardex products, but I know they have at least one that will meet your requirements.


My opinion; worth price charged.

This one, or this one from Mapei will work.

I'm not familiar enough with Ardex products to recommend one.

If you can find Ditraset, that would be my recommendation.

Just finished the SLC job.
Question: How tin set will stick to SLC since is so smooth?

kerdi-Band

I am using Kerdi-Band at the joint between wall and floor. On floor I have Ditra. Wall has paint on it. What kind of thinset do I used in this situation?. Unmodified between Ditra and Kerdi-Band. What do I use between painted wall and Kerdi-Band?


Thanks,
M

The same unmodified will work just fine.
