Consumption is influenced by the roughness of the substrate. On rough substrates the quantities required will increase significantly. In these cases, to obtain real consumption calculation based on in-situ tests might be required.

Surfaces must be clean, sound and free of oil, grease and other contaminants. Carefully remove all loose particles and dust. All substrate coatings, defective renders, formwork treatments and other previously applied materials that may affect the bond adversely should be removed.

In case of active leaks, use a suitable water plug mortar (i.e. Sika®-4a mixed with cement).

Concrete, cementitious substrates
Prepare the surface by grinding, sandblasting, or wire brushing. Remove remaining dust and particles by suitable measures such as the use of compressed air. Repair any damaged concrete with a suitable SikaMonotop® mortar.

Masonry
Prepare the surface by wire brushing. Remove remaining dust and particles by suitable measures such as the use of compressed air. All mortar joints to be flush-pointed with a suitable Sika® cosmetic mortar.

Sikalastic®-6100 FX should be mixed on site in clean containers.

Blend 15 kg of powder into approximately 5.6 litres (maximum 6.2 l) of water using a paddle mixer attachment in a slow-speed drill (400 – 600 rpm). Mix for 3 minutes approximately until a thick, batter-like consistency is obtained.

Leave Sikalastic®-6100 FX to stand for 1 – 2 minutes to allow full saturation to take place. Re-mix, adding a small quantity of water, if required to restore the consistency.

Do not mix more material than the quantity which can be used in 45 minutes.

For the first coat, additional 0.5 litre per bag can be added to the mixture. Do not exceed 6.4 litres water addition per bag.

Sikalastic®-6100 FX can be applied by brush, trowel or roller. Roller application is possible, but not recommended.

Always apply the mix to a pre-dampened surface. High suction substrates require more dampening then dense substrates. However, make sure there is no freestanding water.

 
First coat

The first coat must be worked into the substrate with a stiff brush, while still wet, to ensure an intimate bond to the substrate.

Care must be taken not to spread the material too thinly.

When the material begins to drag or “ball”, do not add more water, but dampen the substrate again.

Allow at least 2 hours (can be up to 5 hours, depending on application conditions) to cure before applying a second coat.

Second coat

Dampen the first coat and remove excess moisture. Brush or broom the mix onto the surface, finishing in the opposite direction to the previous coat.

Finishing

To improve the aesthetic appearance an additional layer can be applied by spray, eventually sponge floated to give a uniform surface.

Under hot or excessive drying conditions fog-spray after the initial set has taken place for as long as practicable.

In cold, humid or unventilated areas it may be necessary to leave the application for a longer curing period or to introduce forced air movement.

Do not use dehumidifiers during curing periods.

Clean all tools and application equipment with clean water immediately after use.

Hardened / cured material can only be removed mechanically.
