Choosing the right paint brush

You will need two or three kinds of paint brushes.

A flat brush for plain surfaces: 
A flat brush can hold a lot of paint, thanks to its thick layers of bristles. This makes the flat brush perfect for plain surfaces like walls and ceilings, as well as doors, trims and baseboards. We recommend the wide flat brush for walls, ceilings, doors and the narrow flat brush for trims and baseboards. 

An oval brush for cutting in:
Cutting in means painting the outer edges of the area you are about to paint, making a border around the surface. That is the ceiling line, edge of walls, around door and window frames and around sockets etc. All the places where you cannot use a roller without getting roller marks on the wrong surface. One can use painters tape to help paint close to edges, but one can also skip the tape and simply cut in with an oval brush. We recommend a wide oval brush for long lines and a narrow oval brush for tight spaces. 

Cut in like this:

First stroke: Hold the oval brush vertically, parallel to the edge your are about to paint, approximately 2 cm from it. Use this first stroke to simply get paint on the surface.

Second stroke: Turn the brush to a horizontal position, apply pressure and use the second stroke to distribute evenly the paint already on the surface, up close to the ceiling line, door frame, or electricity socket etc. 

A brush for hard-to-reach spots?
In the case you need to paint behind radiators, in places where you cannot reach, an angled brush can also be of help. We recommend either a long or shot angled brush depending on your project.  
 

Pro tip:
Break in your brush by bending the bristles back and forth to loosen them up. Pointing the brush downwards, rinse the bristles with water, and squeeze the excess (away from the handle) with your fingers.
