SC 200
DESCRIPTION
Grants SC 200 is a fast setting high build modified cementitious screed for use with Grants waterproofing membranes and tile adhesives. SC 200 can be used for internal/external applications but not for immersed situations like a swimming pool spas etc. It is suitable for concrete floors and fibre cement sheets prior to tiling.
SUB FLOOR PREPERATION
The surface must be clean, dry firm and free of dust oil, grease, wax and curing compounds.
The substrates must be installed according to the relevant standards and manufacturer recommendations.
• All porous surfaces must be primed with Grants PR 100 Primer - 3 parts water to one part primer.
• For non-porous surfaces such as existing tiles, it must be primed using Grants PR 100 Primer neat. For more information not listed, please contact National Tiles for further information.
MIXING
Mix 2-2.5 litres of water to 20kg of Grants SC 200. Mix with a mixing paddle until a creamy consistency is achieved and powder is free of lumps. Allow mixture to stand for 3 minutes remix and use the screed.
Note: Do not over water as this will promote bleed and separation with a reduction in bond and strength.
APPLICATIONS
Apply Grants SC 200 to the primed substrate using a screed bar or trowel to give the required thickness. Minimum thickness is 15mm for bonded screeds or external areas. Minimum thickness should be 25mm on concrete or 35mm on F/C sheet. Maximum thickness applied in any one application can be up to 200mm. Grants SC 200 has a work time of approximately 30 minutes @ 230C.
MOVEMENT JOINTS
Movement joints must be in accordance with Australian Standards AS 3958-2023
COVERAGE
SC 200 will cover approximately 0.5m2 @ 25mm in thickness.
