Base Mounting Block Installation
For wood & synthetic porch floors (& masonry floors if using PVC Block). Not recommended for use with Steel Core Posts.
Follow Installation Instructions for type of Porch Posts you are installing to determine Post trimming, placement, etc. Attach Block to bottom of Post prior to installing Post using 4 wood screws long enough to penetrate through Block and at least 1" into Post. (For Polyurethane Wood Core Posts, use 2 screws and penetrate the wood core.)
1. Pre-drill 4 holes in Block completely through. Hole size should allow screws to pass through snuggly.
2. Hold Block into position with equal amount projecting beyond all 4 sides of the Post. (If working alone, use tape.)
3. Insert a nail into one of the holes and tap it once with a hammer. Mark this hole on the bottom of the Block and on the bottom of the Post, as you will need to know later which Block hole matches which Post hole.
4. Remove nail and Block. Pre-drill into bottom of Post for first screw. Hole should be just slightly smaller than screw to provide good holding power.
5. Reposition Block, with the marked hole over the pre-drilled hole at the bottom of Post. Screw the first screw into place. Using nail, tap a mark onto the bottom of Post to locate where to drill other 3 holes.
6. Remove the first screw once more. Completely smear bottom of Post with a premium grade of long lasting caulk.
7. Reposition Block into place, matching marked first hole. Replace first screw and then install the other 3 screws.
8. Once dry, trim any excess adhesive or caulk from around the edges of Post.
9. Place Post into final position. Since Base Mounting Block projects beyond edge of Post, you can screw through this projecting area for anchoring into porch floor. You will need to pre-drill these screw holes, probably at an angle. These holes can be countersunk, filled with wood filler, sanded, and painted over as needed.
