C800 (M) is a dry pre mix, water resistant, cement based thin bed adhesive for the fixing granite, vitrified tiles, glass mosaic, glass bricks, and ceramic wall and floor tiles. It is suitable for internal and external use and complies to ANSI A 118.4:2005 and BS EN 12004:2017. C800 (M) has a long open time with excellent adhesion and workability. It consists of White Portland cement, oven dried, processed sand and chemical additives including vinyl acetate/ethylene copolymer redispersible powder.

C800 (M) supplied in 25 kg bags must be mixed with potable water only, in a clean plastic bucket or a clean, non-corrosive, uncontaminated metal tub. To ensure a homogeneous and uniform mix, an electric agitator or paddle mixer must be used. The amount of water to be added is 7 liters per 25 kg bag (i.e. approximately 28% by weight). Add C800 (M) to water, turn the contents of the bag carefully and stir frequently. Once mixed allow to stand for 5 minutes and mix again before applying. No further water should be added to the mix. The mixed mortar must be used within 30 minutes. Hard and set mortar should not be remixed. No further water should be added to the mix.
Conmix C800 (M) is rendered in one coat, having a thickness of 3-6 mm. To achieve a uniform thickness, the mortar is leveled with a serrated trowel. The thickness of the ribs will depend on the size and type of tile. Do not spread more than 1 m2 at a time, spreading larger areas may result in the mortar drying out before tiles can be pressed home, resulting in poor adhesion. Once the mortar has been applied, the working time will vary according to the porosity of the surface and ambient conditions. While tiling in wet areas, i.e. swimming pools, shower rooms etc; ensure solid bedding, no voids or air pockets behind the tiles. Do not apply the mortar sparingly, buttering the mortar onto the back of the tile is not recommended but if essential it should be spread over the entire back of the tile to an even depth.
Conmix Technical Service Department will assist in these procedures upon request.
Tiling in newly constructed buildings should not commence until all shrinkage movement and creeping has taken place. Cement based mortars, plasters, renders and floor screeds must be allowed to harden for a minimum period of 14 days before tiling commences. Ceramic tiles should never be fixed with tight joints. Leave a minimum space of 2 mm around every tile. Grouting should not be carried out for at least 48 hours after completion of the tiling. During this period proper water curing must be carried out for hydration of cement.
Conmix C800 (M) must be stored in a dry place, off the ground and well covered. Hard and lumpy material must be rejected.
