AREAS OF UTILIZATION
• It can be used as a waterproofing material under ceramic tiles in all buildings, especially in wet places such as balconies, bathrooms, toilets, and kitchens.
• It can be used on foundations, basement walls, terraces, retaining walls.
• It can be used on surfaces such as exposed concrete, plaster, screed.
ADVANTAGES OF THE PRODUCT
• It is semi- elastic.
• Used indoors and outdoors on horizontal and vertical surfaces.
• It provides the opportunity to apply coating materials such as ceramic and alum
on it.
• It has high adhesion and water impermeability.
• Resistant to shrinkage cracks.
• Applied against positive water pressure.
• Easily prepared, applied with brush, roller, or trowel.
• After curing, it is resistant to water and frost.
PREPARATION OF THE SURFACE
• The surface should be clean, smooth and in good condition, free from all kinds of material wastes and worn surfaces that prevent adhesion.
• Before WERIMIT STROMIT SEMI-FLEX (Semi-Flex Waterproofing Mortar) application on uneven surfaces, such surface should be repaired with WERIMIT WETECH- REPAIR at least 24 hours before the application.
• The flow of water towards the drains should be provided, and it should be ensured that there is no ponding.

APPLICATION
• A: The liquid mixture is poured onto a clean application surface, B: All the powder component is poured and mixed with a suitable low-speed mixer for 3-4 minutes until all lumps disappear. Ensuring a homogeneous mixture without lumps.
• After the mixture is rested for 3-5 minutes, it is mixed again and made ready for use. (Depending on the air temperature, 10% water can be added into the mixture.)
• Can be applied with brush, roller, or trowel.
• It is recommended to add 10% water to the mixture, apply the first layer thinly with a

brush and then move on to the second layer.
• The thickness of each layer should not exceed 2 mm. Drying time should be 2-6 hours
(depending on ambient conditions) between each coat.
• In plaster mesh applications, While the first layer has a wet-dry appearance, the plaster
mesh is placed on the surface and the second layer is applied with the help of a brush, roller, or trowel.
SHELF LIFE
• Shelf life is 12 months when stored in its unopened original package, free of moisture, dry and not exposed to direct sunlight.
