TP REPAIR-800

Cement-based, polymer-modified, fibre-reinforced, class R4, high-strength structural repair mortar

A cement-based, coarse-aggregate, thixotropic, high-performance repair and filling mortar. It is enriched with fibre and polymer additives. It has high strength and does not crack.

Areas of Use

• In the repair of concrete structures
• In the repair of holes, breaks and cracks
• In filling tie-rod holes and core-drill voids
• In forming chamfers before waterproofing
• In vertical repairs

Advantages

• Easy to apply and flexible in structure.
• Does not shrink.
• Provides high adhesion to concrete.
• Thanks to its thixotropic character, it can be used on vertical surfaces.
• Can be applied indoors and outdoors.
• Can be applied up to 7 cm thickness.
• Polymer- and fibre-reinforced.

Consumption	Approximately 16.0 kg/m² per 1 cm thickness
Shelf Life	Shipped in 25 kg kraft bags, on pallets or as sling-bags on request. It is recommended to use the product within 1 year of the production date, unopened in its original packaging in a dry, frost-free environment, stacked no more than 8 bags high, and within 1 week once the bag has been opened. When not in use, the bag must be tightly resealed.

Application

The application surface must be cleared of substances such as form oil, paint and dust. Loose parts with poor adhesion should be removed from the surface. Rust on metal parts should be cleaned off and their contact with the mortar cut with an anti-rust primer. Application can begin after the surface has been dampened. The appropriate amount of water (4–4.5 l of water per 25 kg bag) is placed in a mixing container. The powder is added and mixed with a low-speed hand mixer. After waiting 2 minutes, the mortar is mixed again until a homogeneous mix is obtained. The prepared mortar is applied at up to 5 cm thickness. If greater thickness is required, make sure the first layer has hardened before applying the second. In large-surface applications, the surface is levelled with a finishing trowel. Application tool: trowel.
