The Quickrete company manufactures a number of rapid setup compounds that bond to a variety of building materials, including concrete and cement. Quikwall is a compound described by Quikrete as a "surface bonding cement" made from a Portland cement base, which can be applied to walls crafted with cement blocks. When using Quikrete, the blocks do not need to be mortared together first. The Quikwall bonds the blocks together through the surface application.
Things You'll Need
- Rock dust
- Cement blocks
- Stirring stick
- Garden hose
- Metal ties
Dig a footer for the wall that you want to build that is slightly wider than the width of the cement blocks from which you plan to create the wall and at least 6 inches deep. Fill the footer with rock dust up to level with the top of the footer.
Lay the first row of cement blocks directly next to each other all along the footer. Lay a level across the tops of the blocks to make sure they sit evenly on the footer. If the blocks tilt in one direction or if there are visible gaps between the bottom of any blocks and the footer, add more rock dust to the footer in those areas until all the blocks sit evenly.
Take the cement blocks off of the footer once they're even. Mix a batch of Quikwall according to the packaging directions and spread approximately a 1/8-inch layer of Quikwall over the footer. Place the first row of blocks back onto the footer, once again checking for level to ensure that the footer stayed even during application.
Stack cement blocks on top of the first row of blocks to build the wall to a height of four to six rows. Alternate the seams in the blocks as you would to create a standard, mortared block wall but do not apply mortar to hold the blocks together.
Moisten all the blocks in the wall with a fine spray from a garden hose. Spread a 1/8-inch layer of Quikwall SBC coat over the entire outside surface of the wall, including both sides of the wall and at the ends.
Build any walls that intersect with the first wall once you finish the first four to six rows for the first wall. If you build an intersecting wall, build it to the same height as the first wall and place a metal tie on the top row of blocks in the wall between the intersection block on the second wall and the blocks on the first wall. Continue building the walls up four to six rows at a time and place ties every four to six rows between intersecting walls.
