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

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.
