Add glue at the back of the block at the back and then place a block sitting in a vertical position.
Don’t put any glue past the middle point, stay within the end of the hole.
Alternatively, you can just apply the glue to the end of the back support block if you aren’t sure where the glue should go. Now just place the block vertically on top.
Step 7. Assemble The Cinder Block Bench Seating And Back Posts
Be sure to let the glue dry enough to get tacky before placing the posts into the holes, 10-15 minutes should be fine.
First, consider which side of the posts you want facing up since some sides of the post look nicer than others, depending on the grain and knots. Just gently insert each into the holes, leaving equal spacing on each end.
Wait 24 hours before testing out the bench seating. The reason for this is that the glue hasn’t cured yet and your blocks may slide out of place while the glue is still wet under the added weight.
Feel free to add seat cushions and decorative pillows for extra comfort and ambience to your super sweet cinder block bench!
