FARCOTOP 50

Uses

• Fairing of exposed concrete or masonry surfaces
• Fairing of concrete or masonry surfaces to receive protective or decorative coatings
• Levelling new and old concrete surfaces, infilling surface imperfections, filling small holes
• Filling and covering tiny cracks in precast and in-situ concrete
• Joint filling of cement and gypsum boards in combination with polymer nets
• Levelling the mosaic and stone surfaces prior to parquet installation

Advantages

• Good adhesion to prepared concrete, masonry, mosaic and stone
• A waterproof layer, Low permeability
• Resistant to freeze-thaw cycles and deicing salts
• Recommended for industrial areas as a fairing coat beneath protective coatings
• A good cosmetic for preparing the surface prior to decorative coatings

Instruction for Use Surface Preparation

• The substrate must be sound, firm, clean and free of oil, grease, loose particles, cement laitance, old layers of paint or other contaminants.
• Concrete and concrete block work surfaces should be adequately prepared by use of suitable mechanical means such as grit blasting, high pressure water jetting or needle gunning to produce a lightly textured surface to ensure a good key.
• Open the cracks with mechanical means
• Repair the thick removed areas with polymer modified mortars such as SA12, Sa46 or PC110
• Dampen the surface prior to priming and application

Mixing

• According to the type of work choose one of the emulsion polymers SA12 or SA46
• Dilute SA12 or SA46 with the ratio of:

Polymer: Water (1:1 to 3)

• Gradually add powder to the solution while mixing, until a homogenous and lump free paste is achieved.
• Only mix that quantity of material that can be used within an hour at 25˚c.
• In order to have the same colour as exposed concrete, mix white and grey FARCOTOP 50 with each other

Application

• Apply the primer after dampening the substrate and prior to FARCOTOP 50, by brush.

(1 part polymer+ 3 parts water (volumetric))

• The suitable working temperature is 10˚c to 35˚c.

• Apply with trowel, the maximum thickness for each layer is 2 mm and recoat if necessary with 5 hours interval.

• Avoid direct sunlight and wind at the early ages as it may increase the water evaporation and leads to cracks and lower quality. Dampen the treated surface a few hours after.

• At hot days keep the materials in cool and dry place, at high ambient temperatures use cool water.

• At cold days keep the materials at least one day before usage at room temperature and mix with warm water. It is not recommended to apply at ambient temperatures lower than 5˚c as it contains cement.

Coverage

• It depends on the substrate condition and the porosity, but generally it is about 2 to 3 kg/ m² for 2 mm thickness.

• For local usage and crack filling 0.5 to1.5 kg. The consumption of SA12 or
