- Indoors and outdoors,
- It is used for bonding building elements with high water absorption rate such as gas concrete and bricks.
- Ambient temperature should be between: +5°C and +35°C.
- Make sure that conditions such as frost, rain, strong winds and high temperatures are not present.
- The application surface should be cleaned from dust, dirt, paint, oil and similar substances that will reduce adherence.
- Using a scale, pour 5,75-6,25 liters of clean water into a clean mixing bowl.
- Slowly add ExperWall CG 21 to the bowl filled with water and mix with a low speed mixer until a homogeneous and lump free mixture is obtained.
- The mixture is allowed to rest for approximately 5-10 minutes, then mix again for 1-2 minutes and made ready for application.
- The adhesive should be spread over the entire surface, combed with a 10x10x10 mm comb and applied with the same thickness.
- The mixed mortar is applied to the surface with a trowel or a 10x10x10 mm wide notched trowel. Make sure that the mortar is applied over the entire surface.
- Horizontal and vertical joints should be maximum 3 mm.
- The bounded blocks should be fixed by ramming from the top and side.
- The bottom and side surfaces of the gas concrete blocks, which will be applied in the first row, are wetted with water and then the masonry process is started. It is not necessary to wet the gas concrete blocks during the laying of subsequent rows.
- Bonding should be done on the combed mortar within 10-15 minutes.
- Do not apply in weather conditions below +5⁰C above +30⁰C, in rainy and/or windy weather.
- Avoid application in areas that are frozen, in areas with the risk of freezing within 24 hours, in conditions that may prevent the application or that may damage the surface after application.
- Should be stored in its unopened original packaging, in a closed, moisture-free, dry environment, protected from frost. Products should not be overloaded in a way to damage their packaging.
- Shelf life under appropriate storage conditions is 12 months from the date of production.
