Successful plastering is very much reliant on the cleanliness of your tools and water. The slightest contamination will make the perfect finish almost impossible.

Dried flakes of old plaster can find their way into your mixture and onto your wall which leave an obvious scouring mark right across your hard work.

A properly finished plaster surface will have the touch and feel of an egg shell and is not perfectly smooth like glass.

You are almost certain to encounter problems without any adequate preparation of your surface.

If you want to attain a good smooth finish which lasts, then remove loose dust, dirt and crumbly material from the surface which is to be plastered. 

Before applying any primer, wash the surface properly and brush down accordingly. In general, this will be a mixture of PVA glue and water.

The first coat of primer is designed to give a foundation for your plaster and a great fence between the plaster. Without it your plaster may dry out.

Cracks may develop as the wall adsorbs moisture from the new plaster. Prior to plastering, a second coat of the mixture should be applied directly.
