DO:

• Make sure the main structure and columns meet the requirements and are dry.
• Use a mixture of PM-200 or PM-600 as first horizontal layer adhesive with 2-5 thickness. Apply it with a trowel.
• Use block adhesive PM-100 on the vertical blocks.
• Use a waterpass to ensure the blocks have been layed evenly.
• Use PM-100 for horizontal and vertical blocks in the second course and in the next courses
• Make sure the blocks are even and in 90-degree angle to each other, using a waterpass.
• Use a rubber mallet to level the block.
• It is recommended to use PM-200 plaster from Prime Mortar because it has been tested and proved to meet technical requirements
• Remove the excess of block adhesive PM-100 which sticks out from the surface. Cover the hollows between blocks using PM-100. Use a trowel to apply it.
• Place an anchor in every 3 courses of vertical block and every 2 courses of horizontal blocks.
• The overlap length of vertical shear in the lower course and vertical shear in the upper course is 20 cm or 1/3 of the overal length.

DON’T:

• Don’t work on a damaged, leaned, or visually unreliable sloof, beam, or concrete column.
• Don’t use conventional adhesive mixture or plaster which has unstable or unmeasurable composition and homogeneity.
• Don’t use fake AAC Blocks which will affect the quality of the final result of the wall construction.
• Don’t use water that is contaminated by mud, oil, or salt to mix instant cement.
• Don’t use a mixture of PM-100 that is too thin or too thick because it can reduce its ability to stick objects.
• Don’t use a bucket that is dirty or has some paint on it.
• If the surface of a vertical block looks leaned, correct it right away, because this would cause extra use of plaster.
• Don’t use a trowel or a hand to level a block, because the pressure won’t be strong enough. Don’t use a metal mallet, because the pressure would be too strong.
• Don’t wet the surface of a wall before applying plaster.
• Don’t use a hammer to cut a block, because it will cause an uneven vertical surface.
• Don’t make a passage for electricity pipes with the depth more than 1/3 of the block width.
