How To Paint Over Polyurethane
Prepare The Room For Painting:
Prior to performing any of this work you need to decide whether you have to work in place as is the case for window and room trim or remove the item [door, window sash or furniture] to outdoors to a better ventilated space.
Outdoors:
1. Choose a spot where you will not stain or damage landscaping or patios.
2. Work in the shade – direct sunlight will dry your paint too fast and ruin your finish.
Indoors:
1. If you are working indoors I recommend placing a box fan in the window blowing outside. On the other end of the room open a window to bring in fresh air.
2. Prepare a room for painting; you should first remove all of the furniture. If you don’t have enough extra space in your house to make that possible, then you should move the furniture to the center of the room. Cover it completely with plastic sheeting or an old sheet so it will be protected.
3. Remove any floor coverings like throw rugs.
4. Lay drop cloths down on the floor to protect it from paint spatters, drips, and runs. If you don’t have any drop cloths, sheets can be used in a pinch
5. Place drop cloths or sheets on the floor to protect for spills.
6. Remove electrical wall plates or anything attached to what you want to paint.

1. Use TSP for heavy duty cleaning. TSP is an excellent cleaner for removing heavy deposits of greasy grime, smoke, soot stains and chalked paint from walls, woodwork and floors. It also removes mildew and mildew stains is non toxic and mixes with hot water.
2. Wash all surfaces to be painted.
