Do I need undercoat over primer?

Fatih

Hi,

I have newly plastered walls. I already painted them with a primer for newly plastered walls. I want to apply silk emulsion paint. I was wondering if I can directly use it over primer. Does primer act as undercoat or should I use undercoat before silk emulsion?

thanks for your help in advance.

Defnitily use an undercoat, it will be a far better finish in the long run......

You generally don’t need to apply an undercoat for emulsion paint for basic redecorating work. It’s usually only necessary where you are painting over a much darker colour, in which case you simply apply an obliterating coat of white matt emulsion. Your primer is probably a milky white colour, so that would be a good base to emulsion over.

Check the paint can: you are unlikely to see an instruction from the manufacturers to undercoat ahead of applying emulsion.

No such thing as an undercoat for emulsion.Not even a primer is requied just 20% thinned contract emulsion for a mist coat.Silk is not ideal for new plaster but If you do use it just apply a 10% thinned coat of contract emulsion on your primed walls first, then apply the silk emulsion on to this
