Did the magnetism work? How many coats did you need?

It does work but is very weak even after 3 coasts with Neodymium magnets

How long does it take to cure...and so how long do I have to wait before writing on it with chalk

Hi Most paint coatings have a curing time of 7-10 days, this product is no different. Please allow 7 days for dry paint film to achieve its full cure time before using chalk on the finish. CT Paints

Would this paint work on matt melamine? or would i need to use primer in the first instance?

Hiya, I have used it on plastic soffit board, I did use a magnetic primer first as l understood it would work, with ordinary blackboard paint but it didn’t work, so then l bought this and used 2-3 coats on top of the magnetic primer and got good results. This is not supposed to be necessary but it’s more belt and braces! Prob 3-4 coats of this would do just as well,, but can’t guarantee, hope this helps! L

can this be used on bare plaster?

For any bare plaster you want to mix some emulsion paint with water 50/50 and give it two layers of watery paint before you paint this.
