Chunky cherry roll

In my house on an exterior wall of 15 cm more than thirty years old I have made it repaired two or three times, but without existing more than a few months. For this reason I decided to see what happened myself, proceeded to chop a loose part of the plaster and I noticed with surprise that at the top of the room, there was an important crack, the one that opened to be able to repair it, and I also noticed that the external plaster of it was strong but really separated from the mortar given to the wall
at the time of construction (from what I could find out, it could have been done when it was dry and was already waterproof.
Choose to chop the entire loose thick plaster, seeing that between the mortar and the plaster the wall had moisture, which dried the next day., proceeded to cover the cracks, with a mixture of 3 sand 1 of cement and 100 ml of cherry per liter of water, leaving the cement well and then apply three rows of belts to be able to give the thick plaster again, leaving 2 mm for the fine plaster, below the level of the wall. and covered the entire wall with plastic to prevent burning.
My doubt was created when making the strips, since the wall moistened it but the mortar rejected the water, (did not reach the brick) and thought to make a thickness with the same proportions of 3 sand 1 of cement 1 100 ml of cherry that does not exceed 1 cm thick, will it be possible to fix it to the original mortar or is it at risk of detachment?
I have a few years and I planned to finish it in 4 or 6 days but I see that the reboque must be done immediately, that is correct. or it is variable if it does not suffer heat, sun or too cold. I attach a photo. Thanks to those who can give me help or advice to avoid having to chop everything again.

Hi. Apply a coat of SIKA latex before plastering. This produces a bridge of adhesion between both layers that are of different age. You can add a little of this product to the mix and you will see how it adheres without problems and will not peel off. regards

Thank you for your explanation, I interpret that
interpret that previously it would be necessary to place for 2.5 meters to cover, according to the information of the link about 0.700 milliliters of the product that you recommend mixed with 9 tablespoons of cement for 9 tablespoons of sand and mix
either to paint beforehand with a brush with a thickness of approximately 3 to 4 ml then within 20 minutes, I mix 3 sand, 1 cement and 100 ml of ceresite proportionally according to need
for the 1 cm thick thick plaster or MY GREAT DOUBT I PUT OR DOES NOT CERECIATE THIS REVOKE. THANKS
