Circa 1850 Prime-It is an acrylic primer that's like sandpaper and sealer all in one. It is the only universal primer that goes on virtually any surface and under virtually any paint. Prime-it totally eliminates the need for sanding most glossy surfaces. Prime-it goes on in half the time and covers twice the area of other conventional primers. It dries on most surfaces in 20 minutes and is ready for painting in 2 hours. Remove loose paint, rust, plaster, etc. Clean the surface with TSP and warm water. Remove existing mildew with household bleach. Stir the Prime-it until consistent throughout can. Do not apply below 50 degrees F. Apply Prime-it with brush, roller, or spray. Wait 2 hours before applying top coat. Under condition of high humidity or low temperature, additional drying may be required. Clean up with soap and water.
