A new layer of paint lights up a room and expands the value of your home when it’s available and makes it a place to be while you’re living in it. Windows particularly advantage from new paint, as dampness, bright beams and ordinary use break down the old coat. The best strategy for painting a sash window is to work from the external sash – the piece of the window that is on the outside side – to the inward sash, the piece of the window that is on the inside side of the room. To guarantee great paint adhesion and legitimate curing, paint the window on a dry, quiet day when temperatures are at or more than 50 degrees Fahrenheit.

Preparing the surface

  • Press the low-tack painter’s tape immovably against the glass along all edges. The tape will shield the glass from paint should your brush falter.
  • Press wood putty into any openings or breaks in the wood with a putty cut. Smooth away any overabundance and enable the putty to dry.
  • Sand the wood with 150-grit sandpaper. Tidy off the garbage and wipe the wood with a tack rag or damp cloth. Guarantee that all sanding dust and debris is totally expelled or the paint won’t cling to the wood. Permit to dry.

Painting the sash window

  • Open the sash windows so the inward sash is raised totally and the external sash is brought down completely with the exception of an inch or two.
  • Apply the paint to the external sash’s level muntins to start with, if your window has these. On the off chance that your window does not have muntins, apply the paint to the external sash’s base flat rail. Position the brush so that the broadest end confronts you and the thin, limited side of the brush skims along the muntins or sash. Move gradually one way, guaranteeing an even globule of paint that covers the surface of the sash. Try not to move the brush one way and after that move another, as this prevents an even coat and makes unattractive lap marks.
  • Apply a similar painting strategy when painting the outside sides of the window; even muntins, vertical muntins, sash base rail and top rail, and at that point sash stiles.


  • Abstain from painting in direct sun light.
  • On the off chance that any tape buildup adheres to the glass after expulsion, tenderly rub the glass with a utility knife blade situated at a 45 degree point. Spritz a little measure of window cleaner on the paint to avoid scratches as you rub.
  • On the off chance that tape is excessively troublesome, making it impossible to apply in tight corners, utilize a wide blade, metal putty knife as a shield to shield the glass from the paint.
