New paint brush time

I am going to buy some quality paint brushes and a lot of decorators here recommend Purdy or Hamilton perfection brushes.
The brushes will be mainly used to paint around the edges of wall and ceiling prior to rolling.
And for undercoating & glossing architrave, skirting board and internal doors.
I have noticed Purdy do a large selection and am a bit lost as to which brushes to choose, Hamilton also do a large selectional, its over to you to help me make the right choice.
Will i notice any difference to the finish of the paint when i buy good quality brushes?

probably will notice The trouble with DIY kit is - it`s so C-rap sometimes , even a tradesman finds it hard going . It kind of defeats the object of doing -a good job- yourself . I`d use Hamiltons for Emulsion and Purdy`s for the rest - In fact I do - But I don`t have customers, just my own house

Which Purdy brush do you use for undercoating & glossing?

Purdy Monarch Elite Brushes are the best for undercoat and gloss.

take good care of them. An old, well-cared for brush, paints better than a new one because the tips of the bristles wear finer. Never leave them clogged with old paint.

My old dad taught me to use one set of brushes for white, and one set for colours. I still have some of his old brushes.

A tip you might not know is that if you put your brushes in paraffin after using oil paint, it loosens it and makes it fall out much better than white spirit or brush cleaner does. It is very cheap and the paint residue falls to the bottom so you can use it again (it does not just dilute the paint). I always use brush cleaner afterwards though so there is no paraffin left.

get yourself some tall glass jars like pickle jars. To prevent the tip of the brush lying on the bottom of the jar, getting bent and standing in paint residue, drill a hole in the handles so you can put a long nail through and the brush will hang with the bristles and stock immersed

He's a wise old bird at times.

and when you buy a new brush, break it in with the primer and undercoat before you use it for topcoats. Then any shed bristles will be little extra trouble
