I did a search and found some on-going discussions abnout d-mix, but I wonder where the original instructiuons are. What ever happened to the FAQ section of the forum? (That was a rhetorical question.)
I know it’s a mix of ready mix, plaster, and pva primer, but I have a few questions …
Some one said that it stays workable in the bucket for sevral hours but sets quickly on the wall. How quickly?
What type of ready mix … standard or lightweight or plus 3?
I have read comments in other discussions about puitting a few drops of detergent in the top coat to make it more workable. Is that useful here as well?
How do you calculate how much you will need? I know the sf of my walls, but how far does the mix go?
I’m sorry, I thought you wanted it done the right way.

The D-Mix is one of this things that you have to get your hands dirty. Instructions and the right mix for each job and each person is relevant to your plastering skills.
The good thing about the D-Mix is that is very forgiving. You can rework the same materials by applying more stuff or even water.
The way to learn is to get 5/gallon JC (green is fine) one gallon of PVA primer. The cheaper the better. And some plaster of Paris.
The basic mix is 2-1/2 gallons of JC. With enough primer to make it rollable (like heavy soup) and one quart of pop. (one coffee cup.?)
First you mix the JC with the primer and the pop comes last. You need to use 100% lambskin roller and apply the mix in 4x4 feet sections. When you apply the second section you go back and rough smooth the first. And keep going. If you have a helper is much better. When you finish the whole wall you can go back and do the final finish with clean taping knifes. If you have a problem with the finish, spray some water or roll more d-mix.
The pop makes the d-mix to dry faster and pva is your thinner.
One more thing. Apply the mix the same way you apply sand finish paint. You don't empty your roller in one spot. You empty the mix in 3-4 spots then you rock & roll.
Good luck.

I'll have a helper so it should go ok.
Any idea how much mix will be needed?
You empty the mix in 3-4 spots then you rock & roll. Can youy explain this a little more?

For a small room you need a 5/gallon.?? But is relevant to how thick and how you apply the mix.

You dip your roller and you hit the wall on 4-6 spots before you start the rolling.
You don't want to empty the mix in one spot then try to spread with the roller.
Is like applying sand paint.

Thanks. In this case it would be a thin coat, just enough to cover surface flaws.

Wet your roller for 5 minutes before you use it.
Make your d-mix like thick paint.
Roll and skip an area 4x4 before you start the rolling just like sand mix paint.
And don't try to make it very smooth until you have one or two walls done.
Good luck.

Dino-Do you ever use a bonding agent before D-mix?You get out of life what you put into it......minus taxes.

Hi Marv.
The bonding agent can create big problems some times.
You can use it on new surfaces where you don't have the possible delaminating problem. The bonding agent can soften the previews paint and cause the paint to come loose......
..together with the d-mix.
I use it once and it turn out to be the best wall stripper.
The joint compound on the other hand is ...a bonding agent. This thing sticks to anything.
