You don't mention what kind of drain you have, but if you need to switch to a clamping drain you can remove the grate off the current drain and use an inside pipe cutter in your drill to cut the drain off.

An inside pipe cutter is basically a drill bit with a toothed wheel on the end. It can cut inside or outside the pipe.

The material to build the pre-slope is very similar to Quikrete Sand Topping Mix. If you want to make it a little easier to work with, throw a couple of shovels of sand in with a 60lb. bag of topping mix. You can add a little water at a time until it will hold together.

Well i have my drain in and i am ready to start with the mud bed. I have some 4-1 but it says to use a "slurry bond coat" on the bare concrete before i put down the 4-1.

What do i use for the slurry bond coat?
Should the mud be go on top of the slurry when it is still wet?

Thanks.

You can use a modified thinset mixed a little wetter than normal for the drypac bond coat. A 3/16 v notch trowel works well for the bond coat application.
Apply the drypac mud onto the bond coat while the thinset is wet.

Thanks, thats what i figured. And after the liner goes down do i have to put down a bond coat before i add more 4-1?

No, it goes straight down on the liner.

Hello...I am new here....I have a problem..The marble surface of my counter tops are badly scratched, worn, or needs major work...what can i do..Looking for solutions...

Please start your own thread on the topic Kate.

For minor wear and scratches I'd recommend Aqua mix stone enhancer and buffing, but it sounds like you have a more serious problem.

Marble is a relatively soft stone and takes sanding and polishing well. What needs to be done is sanding the counters with a progression of finer grits, starting at 50 and going to about 4000 grit. Then a sealer/enhancer and a final polish. This should be done profesionally and will involve taking your counter tops off and away to get worked on. Contact your local granite and marble shops. Unfortunately, you should expect a bill of a couple of thousand dollars or more.

Thanks for the reply...

Drain in, ready to start.

Bond Coat

Finished, I guess i should have cleaned the cement dust off my camera...



How long should this cure? It is Mapei 4/1.

Overnight should be fine.
