Thoroughly dampen the block wall with water - dry block will draw the water from the mix making it difficult to finish and can cause inconsistent color and cracking especially in hot temperatures.Īpply a consistent 1/8 to 1/4 inch coat of QUIKWALL to both sides of the block. Once the first course is set, dry-stack the remaining block in a running bond pattern to the desired height - all corners should use an interlocking pattern. Tip: check your alignment and level every 3 to 4 blocks. Remove the blocks and lay a 1/8 inch bed of QUIKWALL on the footing - the QUIKWALL mix should be workable but firm enough to support the weight of the first course. The proper consistency is achieved when the wet QUIKWALL will “hang” on a trowel held at a 90 degree angle. NOTE: each 50 pound bag of QUIKWALL will require about a gallon of water - additional water can be added in small amounts to achieve a workable mix. Stage the first course of block and snap a chalk line on each side of the block wall as a reference line to ensure corners are square and walls are straight. NOTE: it is important to check local building codes for construction requirements in your area footings should be a minimum of twice the width of the concrete block (for example, an 8”x8”x16” block would require a 16” wide footing) and extend below the frost line to prevent shifting during freeze-thaw cycles. When working with QUIKWALL, rubber gloves and safety glasses should always be worn during mixing and placing procedures.Įnsure a solid footing or base slab for both structural and non-structural walls.
