- Dries similar to off-form concrete
- Excellent workability and smooth finish
- Good adhesion and mechanical strength
- Can be sanded to achieve a smooth finish
- Suitable for thin layer applications (0-3mm)
Suitable Surfaces
- Honeycombed or surface-damaged off-form concrete
- Blowholes and concrete surface imperfections

Application Instructions:
Substrate quality / pre-treatment
All surfaces must be clean, and free from any loosely adhering particles, or contaminants such as dirt, oil, dust, grease, etc.
Cement laitance should be removed by sandblasting, scabbling, etc. to allow for maximum adhesion. All blowholes, honeycombing etc. should be filled with Sika MonoTop® FC mixed to mortar consistency.
Dry and absorbent substrates should be thoroughly pre-wetted, and the surface allowed to dry (to achieve what is referred to as a ‘saturated surface dry’ condition) before application commences.
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.
Colour Accuracy Disclaimer: We have taken care to display the most accurate visuals of our products. However, we are not responsible for the colour accuracy of the device you are viewing our swatches on. These variations arise due to different computer monitors and devices (make, model and technology, as well as resolution, contrast and brightness control settings) in much the same way a scan will differ from an original image and a colour photocopy. Furthermore, coatings can exhibit variation in perceived colour depending on gloss level and application method. If you require a very specific colour match, please make your selection via actual swatches and colour boards available at our showroom.
Product Disclaimer: Ensure you read all product, technical and safety data sheets prior to application as liability falls on the applicator. All products must be applied in accordance with manufacturer’s recommended method.
