 How To Paint Over Polyurethane Or Varnish Finishes

Applying Wil-Bond:

• Saturate a rag with Wil-Bond and rub over the surface until the rag “pulls” or “drags.”

• Change the rag frequently as it picks up grease and dirt.

• Promptly dispose of these rags in a metal container. [They are a fire hazard]

• On heavily waxed surfaces use #00 Steel Wood saturated with Wil-Bond.

• Treat as much surface as you can prime in 30 minutes. The “tact” will only last that long.

Tip: Use the 3M green scrub pads to apply the Wil-Bond to contoured and detailed areas, such as moldings and window mullions.

Tip: Use a plastic pail or make one by cutting the top off a clean recycled container. Pour the Wil-Bond in your container and dip the green pad in to saturate.

Applying Primer

Make sure you have all of your priming supplies set up and ready to go. [oil paint, brush, paint thinner] Remember once you start applying the Wil-Bond chemical you have 30 minutes to apply primer.

Tip: Work in a left to right fashion and in a methodical manner.

For example:

  •  Do one side of a door at a time,
  •  One window sash at a time.
  •  Treat and prime one wall of baseboard at a time. [30 minutes]

10. Prime all of the surfaces you have applied Wil-Bond to with-in 30 minutes.

11. Apply Wil-Bond to a new area and prime.

12. Continue in this fashion until your project is primed.

Tip: You will need to keep your primer and paint brush handy.
