If you are doing a lot of painting in your home, then you may have picked up a sash paint brush amongst your collection. The sash paint brush is different from the ordinary types of brush which you use to slap paint onto walls or across the outsides of buildings, and you will only be able to use it in certain circumstances. The sash paint brush is designed to be used on the edges of window frames, or along sash windows, so when you are painting your whole house, it can come in handy. Don't use this type of brush on walls or doors, as it will not be as effective as an ordinary brush, and you could damage it.

Step 1 - Clean the Area

Before you use your sash paint brush, you should be sure to give the area involved a thorough clean. You will need to use a new cleaning cloth, and simply wipe it around the area where the sash brush is about to be used. This will serve two purposes. Firstly, it will prevent the brush from picking up any dirt and dust, which will then be transferred back into the paint, and it will also stop the dust from being set inside the paint, which can leave your window frame looking as though it has measles. Keep the side clean by brushing it out if you have stopped painting for a short while.

Step 2 - Using the Brush

You now need to turn your attention to the brush. If this is the first time that the sash paint brush has been used, then you should just run your finger over the edge of the bristles. The brush has been cut so that there is an angle on the end of the bristles. You should use the brush with the longer bristles facing outwards from the window, and the shorter bristles moving on the flat surface of the window frame. Remove any loose bristles that you find.

Step 3 - Dip the Brush

You are now ready to start painting. Spread out a little oil-based paint on the bottom of a clean paint tin or tray, and then dip the brush in. You will need to hold it at an angle, so that all of the bristles are covered. Take it out of the tray, and put it on the corner of the window frame, with the long bristles facing towards you. Move the brush along the edge of the window. Repeat for all of the sides. If you are using a latex paint, then you should use shorter strokes, and try to avoid putting too much on your brush at one time, as this can leave lumps.

Step 4 - Clean the Brush

Once you have finished, if you used oil paint, then take some mineral spirits and thoroughly clean the brush. If you used latex paint, then run the brush under the sink until the water under the brush runs clear, free of paint.
