Semi Flex Waterproofing Mortar

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.

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.
