DIRECTIONS

Wear adequate protective clothing, safety glasses and chemical resistant gloves. On a sealed surface wet your stains before applying GG Grease and Grime Remover. On a bare surface apply directly on your stains.

A. SURFACE PREPARATION

1. The substrates must be structurally sound, solid, stable, dry, clean and free of grease, oil. paint, dust, tar, wax, curring agents, primer, sealer, or any other substance which may prevent or reduce the adhesion of this product. Painted surfaces surfaces must be stripped to it’s natural state.
2. Uneven concrete surfaces can be smoothed out with DYNAPLAN 150. Expansion joints shall be probuded through the Adhered Manufactured Stone Masonry Veneer (AMSMV) from all construction or expansion joint substrate. Do not cover expansion joints with mortar.
3. Installer must verify that deflection under all live, dead and impact loads of substrate do not exceed industry standards of L/360 for ceramic tile and brick or L/480 for AMSMV units or stone installations where L=span length.

B. MIXING

1. Use a clean mixing vessel and pour approximately 5.5 to 6 litres of cold clean water and then add 22.7 kgs. (50 lbs.) of MVM gradually while mixing. Use a slow speed mixer (approximately 150 R.P.M.). Mix thoroughly to a homogeneous and smooth consistency. Avoid air entrapment by prolonged mixing, which if occurs will lower the compressive strength of the mortar.
2. Permit the mix to slake for 10 to 15 minutes.
3. Re-stir the entire contents of the vessel without adding any more water to the mix.
4. The pot life of the mix is approximately 4 to 6 hours.
5. Some stiffening of the mix may occur before all the material is consumed. When this occurs, simply re-stir by hand or machine, but DO NOT add any more water.
6. Wash your mixing tools immediately with water after use.

C. APPLICATION 

Use a recommended notched trowel with adequate depth to achieve a 100% mortar contact to the back of the Masonry Veneer. Use the flat edge of the trowel to spread a thin coat over the substrate then apply additional material and comb the mortar with the notch side of the trowel. Do not spread more mix than can be covered with the tiles within 10 to 15 minutes. Otherwise, a skin may form on top of the mortar and proper adhesion will not be achieved. Place the veneer firmly into position with a slight twisting motion.
Then once the veneer has been set, properly beat in the veneer with a beating block in order that at least 1/4 of the thickness of the veneer is set into the mortar bed. Finished mortar bed thickness should be between 3/32nd to 1/8th inch (2.5 - 3.0 mm) thick after veneers are beaten in without any voids or air pockets. Ensure that all alignments and adjustments are performed immediately, do not exceed 30 to 40 minutes. Should skinning occur, remove the dry or skinned mortar and replace it with fresh mortar. Clean out any joints from the face of the veneer immediately with a damp sponge. Do not soak the veneer before application. Ensure that there is 100% mortar contact.

NOTE: Ensure that the veneers are clean of dust, laitance, curing agents, sealer or any
other substance which may prevent or reduce the adhesion of this product.

NOTE: Check the back of the veneer for 100% coverage by periodically removing veneer or tile to make sure 100% of the mortar has been transferred on to the back of the veneer or tile. There is a wide variety of veneers, tiles and stones on the market. Make sure a “non-sag” test is performed prior to installation. Depending on the type of job and veneer, shims, spacers or any other type of mechanism may be required to maintain a level finish.

D. EXPANSION AND CONTROL JOINTS

Provide expansion and control joints where specified. Do not cover any expansion joints with mortar. Cut veneer on both sides along the edges of the expansion joints. Also insert
the specific compressable bead and sealant to caulk the expansion and control joint.
Follow ANSI AN3.8, “Requirements for Expansion Joints”.
