APPROX 10 YEARS AGO I USED OLYMPIC LINSEED OIL SOLID COLOR STAIN ON THE EXTERIOR SIDING. CAN I NOW USE WOODPRIDE ACRYLIC LATEX SOLID COLOR STAIN OVER THIS?
Given your area of the world,I would suggest the surface has received enough weathering to allow for the linseed oil to have been depleted. I suggest you apply a cup of water to an area which does not receive a great amount of weather. If the water absorbs and is not repelled, the surface should allow the Latex solid to adhere. Check with your local paint dealer for his recommendation.
