Greenseal Flexi 201 is a flexible cement based on a two component polymer modified waterproof coating. It is suitable to apply to concrete and mortar to prevent water infiltration and to fill and seal pores and voids, cracks and hair lines of all substrates and yet provide a breathable coating which allows water vapour transmission. It is ideal as a protective layer against aggressive gas such as carbon dioxide and also frost and thawing salts.

Greenseal Flexi 201 consists of Portland cement, selected and well graded sand and plasticiser, formulated with specially selected and graded fine quartz and high quality latex to create a brushable, smooth slurry with excellent bonding and adhesion to most substrates.

GS 201 is supplied in 2 components(GS 201 is packed in 33 kg set-Powder - 23 kg & Polymer liquid - 10 kg), To generate a consistent slurry, pour the liquid component into a pail and then gradually add the powder component to the liquid. While mixing, use a stirrer to stir the mixture until the mixture is free from lumps. Take note of the consistency of the slurry. The consistency of the slurry can be altered by reducing or adding in powder component.

Apply GS 201 with a stiff brush or spray onto the prepared surface with at least two coats. The interval of each coat should be 1-2 hours minimum. To avoid pin holes and ensure full coverage, apply each brush coat in different directions. For large spaces, spray is recommended by using a worm-gear type of spray equipment. For best results, apply GS 201 under shaded shelter to prevent rapid drying of the coating.
