Last fall my contractor installed 6 inch cedar lap siding. The siding is vg cedar with a factory prime coat (oil based - all six sides) and a finish coat (acrylic) on the exposed side. We used stainless steel nails. The trim is finger jointed pine, also factory primed on all six sides, with one finish coat (acrylic). My intent is to wash it all with a mild solution of TSP, then paint the second finish coat.
If I set the nails, and fill, what is the best filler to use and do I need to prime before I fill, and do I need to prime after I fill. If I need to prime, will a latex based primer be better than oil based. It seems to me that putting an oil based primer over the acrylic finish coat is not a good idea. (In either case, I plan on a touch up of one finish coat over the filled areas before I put on the second coat.) In the past I have used 2 part epoxy filler (Abatron), but it is a pain. Would Elmerís int/ext wood filler do the job?
If I donít set the nails, I will insure they are flush. Do I need to prime them? If so, is a latex based primer okay. Again, I am not sure about using an oil based primer over the acrylic first coat.
Any advice will be appreciated. Thanks.
