BETEC® FLOORTOP 860

Product Description

BETEC® Floortop 860 is a cement based, steel fiber reinforced filling mortar with high initial and final strength development to class C80/95. BETEC® Floortop 860 is suitable for high performance repair and surface coating in industrial flooring and road applications.

Advantages

• High early- and final strength development to strength class C80/95 and high flexural strength for a durable repair for static and dynamic loads.
• Frost and de-icing salt resistant.
• CE certified according to EN 1504-3.

Certification

• CE certified according to EN 1504-3.

Field of Application

BETEC® Floortop 860 is used in industrial flooring and road applications, such as:

• Repair and surface coating applications in industrial floor areas.
• Cavity filling and expansion joints repair in road constructions.

Application

1. Preparation of Substrate

• Substrate preparation has to be according EN 1504-10 part 7.
• The substrate has to be free from dirt, grease, laitance, loose concrete, loose particles or layers which could adversely affect adhesion.
• Remove all damaged concrete and prepare substrate by sand or grid blasting, high pressure water jetting, or other methods until base concrete is exposed, offering sufficient roughness (bond) and open pores.
• The substrate must be pre-wetted with clean water until saturated. The substrate should be damp, but without free standing water.
• The substrate must be frost-free and have a cohesion of minimum 1.5 N/mm².
• Exposed or corroded reinforcement steel needs to be treated with OMNITEK® CPC.
• A bonding primer with BETEC® 022 needs to be applied to prepare the substrate.

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 4/5 of the required quantity of water into the mixer and mix for 2 minutes. Add the remaining quantity of water. The water content can be varied to obtain the desired consistency. Never use more than the maximum water quantity. Mix for an additional 2 minute until a lump-free, homogeneous mixture is obtained.
• The mixing time depends on the type of mixer. 4 minutes is the minimum.
• Once the mortar is ready mixed, apply immediately. Do not prepare more material than can be used within the open time of the material.
• When the mortar starts to set, remix but never add more water.

3. Application

• The mortar is manually applied. When grouting large areas, apply the grout by using worm/screw pumps.
• Apply fresh-in-fresh to the previously applied BETEC® 022 mineral bonding primer.
• Press firmly into the application area to ensure proper adhesion and to compact the material. Take particular care in the areas around and behind reinforcement bars.
• The material can be applied in several layers. Especially when repairing large voids it is recommended to work in several application steps.
• Do not apply the material if the ambient temperature is below 5°C or expected to fall below 5°C within 24 hours.

4. Curing

• After treatment has to be according EN 13670 in combination with DIN EN 1045-3.
• In warm or windy conditions protect the applied
  material from dehydration by mist-spraying with clean water or protective tarpaulins until the initial set has taken place.
• In cold conditions cover with insulated tarpaulin, polystyrene or other insulating material. Protect surfaces against frost and rain until final set has taken place.
• In cold, humid or unventilated areas it can be necessary to allow for a longer curing period, or to introduce forced air movement to avoid condensation. Never use dehumidifiers during the curing period or within 28 days after application.
• The after-treatment should be at least 5 days.
• The after-treatment should take place as soon as possible, at the latest when the material surface starts to set.
• As an alternative to the conventional treatment methods, suitable curing agents can be used to prevent rapid water loss.

5. Cleaning and maintenance

• Mixing and application equipment should be cleaned immediately with clean water. Hardened material needs to be removed mechanically.

6. Special remarks

• Cementitious materials can lead to incompatibilities under certain conditions in combination with non-ferrous metals (such as aluminium, copper, zinc).
• Low temperatures reduce flow and delay the early strength development. High temperatures accelerate the strength development and decrease the open time of the material.
• Depending on geometry and application thickness, adding reinforcement steel can be necessary.
• Repaired areas can be coated after 7 days with protective or waterproofing coatings depending on the ambient conditions.

Health & Safety

BETEC® Floortop 860 is a product based on cement and can therefore cause burns to skin and eyes, which should be protected during use.
Wear gloves and protective eye shields.
Wearing a dust mask is advised.
Treat splashes to eyes and skin immediately with clean water.
Consult a doctor when irritation continues.
If accidentally ingested, drink water and consult a doctor. Users must comply with all risk and safety phrases. MSDS’s can be obtained from GCP Applied Technologies or from our website. GISCODE ZP1.
