APPLICATION INSTRUCTIONS

MIXING

For larger volumes, pour approximately 4.1 litres of clean fresh water into a suitable mixing container and slowly add all of the powder while mixing continuously with a Sika mixing paddle attached to a slow speed (500 r.p.m) electric drill. Reduce speed if required so not to untrap air into material. Thoroughly mix until a smooth, lump free consistency is achieved - minimum mixing time of 3 minutes is recommended.

For small volumes and partly mixing by hand, add 3 volumes of the Sika MonoTop® FC to 1 volume of clean fresh water and mixed thoroughly until fully lump free consistency is achieved.

The consistency can be adjusted by using less water if desired.

APPLICATION

Apply Sika MonoTop® FC to the prepared and dampened surface according to general plastering methods using a spatula, trowel or similar. Maximum thickness in a single layer = 3mm. If the Sika MonoTop® FC is to be over coated, as soon as the mortar layer has initially hardened, a fine gripping surface, comparable to sand paper, should be achieved by evenly rubbing down with a dry sponge or similar.

CURING TREATMENT

In moderate ambient conditions Sika MonoTop® FC does not require curing.  On hot substrates and windy conditions protection to the substrate and  curing may be necessary. If curing is required cure as soon as possible using in line with sound concrete practice.

CLEANING OF EQUIPMENT

Clean all tools and equipment with water immediately after use. Hands and skin should be cleaned with warm soapy water. Hardened Sika MonoTop® FC can only be removed mechanically.
