Application

1. Preparation of Substrate

• The substrate preparation must be in accordance with DIN EN 1504-10 section 7.
• The substrate must be free of dirt, grease, laitance, loose concrete, loose particles or layers that could adversely affect adhesion.
• Remove damaged concrete and prepare the substrate by sandblasting, shot blasting or, high-pressure water jetting or other methods until the grain is exposed and sufficient roughness (bonding) is achieved, and the pores are open.
• The substrate must be moistened in advance with clean water. The substrate should be damp, but without standing water. The substrate must be frost-free and have a surface tensile strength of at least 1.5 MPa.

2. Mixing

• The product has to be mixed using a suitable forced action mixer (400-600rpm). The mixing head must be completely immersed in the powder.
• Add the entire required amount of water to the mixer and mix for 5 minutes until a lump-free, homogeneous mixture is obtained.
• The amount of water can be varied to achieve the desired consistency. Never use more than the maximum permissible amount of water.
• The mixing time depends on the type of mixer and is at least 5 minutes.
• The mixture must be left to rest to release any air trapped during mixing.
• The grout should be poured into the area to be grouted as soon as possible after deaeration. Only mix as much grout as can be used within the processing time of the material.
• If the grout cannot be processed immediately, it should be briefly remixed before pouring. Never compensate for reduced flow behaviour by adding additional water.

3. Application

• The material is always poured or pumped from one side or corner in a continuous operation. If formwork is used, it should be impermeable and non-absorbent. To prevent air pockets, sufficient ventilation holes or slots should be provided.
• Due to the self-levelling properties of the grout, additional poking is not necessary. The use of vibrators is not permitted.
• When casting large areas, apply the grout using screw pumps.

4. Curing

• After treatment must be carried out in accordance with DIN EN 13670/ DIN 1045-3.
• In warm ambient conditions or when exposed to wind, the grout must be protected against drying out by covering it with foil, placing water-retaining covers on top or continuously spraying it with clean water. In cold ambient conditions, protect against moisture loss and cooling with insulating tarpaulins, insulation materials, heatable cover sheets or other insulating materials. Protect surfaces from frost and rain until final setting.
• In cold, damp or unventilated areas, it may be necessary to allow for a longer curing time or to use forced ventilation to prevent condensation. Never use dehumidifiers during the curing period or within 28 days of application.
• It is recommended to leave the formwork in place for at least 48 hours.
• The curing period should be at least 5 days.
• Curing should take place as soon as possible, at the latest when the surface of the material begins to set.
• Suitable curing agents can be used as an alternative to conventional curing methods.

5. Cleaning and maintenance

• The mixing tools should be cleaned with clean water immediately after use. Hardened material must be removed mechanically.

6. Special remarks

• Under certain conditions, cement-based building materials can lead to incompatibilities in connection with non-ferrous metals (such as aluminium, copper, zinc).
• Low temperatures slow down flowability and delay setting behaviour and strength development. High temperatures can accelerate setting behaviour and strength development and reduce the processing time of the material.
• Depending on the geometry and grouting height, the use of reinforcing steel may be necessary.
• The lateral grouting protrusion should be kept as small as possible (approximately 20-50 mm).

Health & Safety

BETEC® 110, 140, 180 and 516 are cement-based products and can therefore cause irritation to skin and eyes, which should be protected during use. wear gloves and protective eye shields. Wearing a dust mask is strongly recommended. Rinse splashes on the eyes or skin immediately with plenty of water. Consult a doctor if irritation persists.
