SLC: Mixed Feelings


Looks like my feelings are no longer THAT mixed. SLC is wonderful product. I think I could get it right even with RS if I would do it properly.

Yeah, I guess laying out tiles and then do the walls would be gross.

What protection would you recommend? I usually use plastic while painting. Some people recommend paper.

SLC: Mixed Feelings


Plastic should never be used as a drop cloth on the floor. Plastic is to cover furniture. Use either paper or cotton drop cloths, like the ones painters use.

Plastic can be slippery and will easily move. Plus when a drop of paint falls on plastic, it will not soak in, so you step on it and track it somewhere else. Use cloth.

SLC: Mixed Feelings


Thanks Jaz,
Actually, let me rephrase myself.

Normally I don't put any cover on the floor except for the strip of blue tape where roller touches the floor. Then am trying to be as neat as possible. Even if I have 1-2 drips here or there I can wipe them off easily.

Now here I have different story. Floor is unfinished. There will be a lot of dust from sanding. So you're right, I am gonna get myself roll of brown paper from Lowes and use it as a cover.

Sounds good to me. Drops are easy to see and wipe up. Roller mist you can't see.

SLC: Mixed Feelings


Heya guys,

I am back! Wow! Its been 5 months since my last post.
Sorry for the delay. I had to do some other projects.

Anyway, walls were finished and painted, tiles were marked and cut. But before I'll start laying them down I have couple questions.

First is that I have some cracks in my SLC. They dont look very deep. I hope its nothing serious.




What do you think? Can I lay the tiles over it?

Second, its rather belongs to another topic, but since I am here... Is this AcrylPro Ceramic Tile Adhesive a right stuff for the job? Will it hold well? Is there shelf life for it because I have it (unopened) for few months.


Thank you in advance,
almazon

AL,
Are those your pencil marks or did you pour over existing tile?
As far as your MASTIC that came from Home Depot - NO don't
use it on your floor. A bag of Versabond from HD is about 15 bucks
a bag. Use that- BACK-BUTTER your tile also.

Sorry those cracks are more than a little.

How deep was the pour. Was it primed right. Water mixed to the T .
Or maybe you are having movement on the substrate. Whatever the case may be, that SLC will need to come out.
It will only just progressively get worse once tile is laid ....and tiles will crack.

Yes, those are my pencil marks. What is BACK-BUTTER?

PS. Yes, I got it about BACK-BUTTER. Nice Idea!

Damn, thats really sad news. And there is nothing I can do? Maybe seal it somehow.

It was 2 pours. Both times primed well.
Water mixed to T?

It's not the sealing. You have a cracked substrated. You need to determine what cause it. Could it be flex on the floor. Whatever the case may be, identify and address this before you tile. Just because you poured SLC and now have a level floor, it does not mean that you can tile it. Waste effort if you tile ontop now. The tile will crack on the loose substrate.

Ok, but the tile was there before and it did not crack. It was sitting on mud bed though.
Maybe I have a chance?

Almazon,

If you don't take that j**k back, both products, I will never talk to you again!

Cracks; Did you forget to make sure the floor was stiff?

Makes all the difference in the world pal. Your old tiles were no where near the subfloor. Besides the cracks, is the SLC solid? Tap with the handle of a screwdriver how does it sound compared to other areas? Any give when a heavy person steps on and off? Can you tell? Maybe look from below.

Jaz, thanks for your response!

By tapping I found a few hollow spots near the cracks.
Just few. The rest of the floor is solid.
What are my options?

I had no idea about checking the floor for stiffness.
By same tapping?

Almazon -

IMO, I would just out the brakes on, take 3 step back and just do some basic reading.
Mastic is a big no. Pre mixed grout. The only thing premixed I would consider is urethane or customs epoxy - but those are even a far stretch....I'd choose Spectralock anyday.

But fundamentals like a $18 bag of thinset, having the right substrate, are your joist ready to support your tile, etc - these are all fundamentals you should know before taking the project headon.

SLC aint' cheap nor is I assume your time and labor.
I could live with 1 hairline surface crack but what you have is a bigger problem.

I know you mentioned those 2 big tile stores are just a earshot away. Have you considered just getting a bid or 2 from one of their tilesetters....

There are no joists involved here since I am doing this on Concrete Slab of 1st Floor. Unless there is something I missed.
And I have no basement either.

It look like those cracks are from 3rd layer of SLC at the thinnest part. At least I think so.

What worse outcome will happen if I use these materials over those cracks?
