SURFACE PREPARATION: As with all coating systems, surface preparation is of prime importance. Remove all grease, oil, dust etc.
Spelled concrete should be cut back to sound concrete and made good with suitable cementitious repair mortar. Conventional concrete curing compounds should be removed before application. Roofing tiles should be firmly bedded and grouted before application
MIXING: RHEOSEAL CM supplied in pre-measured units and should be mixed on site utilizing clean containers. Slowly add the powder to the liquid and mix, using a slow speed drill fitted with a suitable paddle. Mix and use. Do not mix more material than can be used in one hour.
NOTE: Although RHEOSEAL CM is supplied in pre-measured packs. Part packs can be used by mixing 2 to 2.59 volumes of powder to 1 volume of liquid. Mix thoroughly and keep mixed during application. DO NOT RETEMPER WITH WATER.
APPLICATION: Damp down the concrete surface with clean water. Whilst damp, but free from standing water, apply using a short, stiff bristle brush or roller. Trowel application can be undertaken as necessary. For heavy 6-10 mm depressions, honey-combs etc. use less gauging liquid and mix to the desired consistency. Where more than coat is found necessary to achieve the desired thickness, apply the second or subse- quent coats after the previous coat has dried.
It is recommended to reinforced all corners, joints & cracks with Rheotec Mesh 65. The Rheotec Mesh 65 shall be embedded into the first coat whilst it is still wet and covered fully with the second coat. All liquid application should be applied in atleast two coats to achieve the desired thickness.
For general resurfacing, each coat should be of minimum of 1 mm thick
