Sika Repair 20F for repairing and leveling concrete

Sika Repair 20F mortar is product for repairing and leveling concrete . It is a single-component PCC mortar based on polymer-modified cement . It contains within itself addition of microsilica and is reinforced with synthetic fibers. The mortar is primarily used for manual reprofiling and leveling of rough concrete surfaces. As a result, a layer from 4mm to 20mm when applied to the entire surface and up to 40mm when filling local cavities.

Capacity : 25kg

Features:

• Non-toxic material
• Increased resistance to penetration by water and chlorides
• Product with high resistance to sulphate corrosion
• Good strength, waterproof and frost-resistant features
• Compensation for early shrinkage thanks to the addition of synthetic fibers
• Good adhesion without the use of a bonding layer
• Ease of obtaining perfectly cosmetic surfaces
• Easy to prepare
• Easy to apply

What is the use of 20F putty?

Putty for repairing and leveling concrete Sika Sepair 20 F is intended for structural and non-structural repairs by hand. It is ideal for concrete exposed to increased environmental aggression. It has its uses in general construction and hydrotechnical construction .

How to apply mortar correctly?

Sika Repair 20F can be applied using traditional techniques. Of course, you can apply the mortar by hand or wet spraying . Please remember that the substrate should be matt and damp before applying the mortar. While the bonding layer is applied Sika Repair 10F onto the previously prepared substrate with a stiff brush apply it to the surface with a rubbing motion . Apply Sika Repair 20F mortar onto the fresh bonding layer using a trowel or trowel. The layer must be pressed to the substrate and then removed with a shearing movement. If the use of Sika Repair 10F is not necessary, the 20F mortar is applied in this way on a matt-damp substrate.

INFORMATION ABOUT THE APPLICATION

Mixing proportions

Sika® Repair-20 F : water - 100 : 14 by weight 3.5 liters of water per 25 kg bag. To increase the stickiness and stability of the mortar (e.g. in a vertical, hanging or ceiling position), the amount of water can be reduced to approx. 3.25 liters per 1 25 kg bag.

Wear

Theoretical consumption: ~18.5 kg/m²/cm. Practical consumption depends on the roughness of the substrate, application method and losses during application.

Layer thickness

Minimum 0.5 cm / Maximum 1.5 cm - leveling mortar. When repairing small local defects - maximum 3.0 cm.

Waiting time / Repainting

The minimum technological break before applying any subsequent layers is (at +20°C):

• for Sika® Repair-30 F: minimum 12 hours
• for one-component Sikagard® coatings: minimum 5 days
• for two-component coatings such as Icosit® and Sikafloor®: not less than 7 days and not earlier until the material moisture drops to below 4%
