>8.0 N/mm2 (mean value after 28 days)Adesive tensile strength
>1.5 N/mm2 (mean value after 28 days)Suitable Substrates
Normal, heavy and light-weight concrete. The average adhesive tensile strength of substrates must be 1.5 N/mm2, with a minimum individual value of 1.0 N/mm2.Substrate Preparation
Treat reinforcing steel with Disbocret® 502 Protec plus (as an anti-rust priming coat) according to the manufacturer’s recommendations.
If manually applied, fine repair mortar Disbocret® 504 is to be applied only on concrete surfaces previously treated with a bonding slurry of Disbocret® 502 Protec plus according to the manufacturer’s recommendations. Then apply the fine repair mortar wet-on-wet on the bonding slurry. If applied with wet or dry spraying method the adhesion promoting layer (bonding bridge) is not required. For anti-corrosive treatment of concrete reinforcement steel Disbocret® 502 Protec plus must be used.
Concrete surface must be sound/solid, clean and free from loose or brittle parts. Substances preventing adhesion, e.g. existing paint coatings, oils, fats/greases, etc., must be removed by suitable method. Substrates (hardened cement paste) must be free from corrosive substances, e.g. chlorides, and removed where required to guarantee proper adhesion of he subsequently applied fine repair mortar on the treated surface.
The edges of repaired areas must be chamfered between 45° to 60°. Substrates must be pre-wetted. Care must be taken to ensure that most of the moisture has been absorbed before the fine repair mortar is applied (flat surface aspect).
Preparation of Material
Pour measured quantity of tap (potable) water into a container and, while stirring with a suitable electric paddle (max. 400 rpm), add the corresponding quantity of dry mortar gradually. Keep on stirring for approx. 3 minutes until a lump-free, homogenous mixture is achieved.Mixing Ratio
| Dry mortar | Water |
| 1 part by weight | 0.12 – 0.15 parts by weight |
| 25 kg bag | 3.00 – 3.75 l |
Method of Application
Fine repair mortar is applied with trowel or scraper, wet-on-wet, blending (pressing onto it) on the bonding slurry. Deeper spalling on vertical surfaces is reprofiled in layers. Fine repair mortar is either dry-spray (e.g. Aliva, Jetmaster) or wet-spray applied (e.g. PFT N2V).Quick drying, caused by sunlight, high temperatures and draught (draft) must be prevented by suitable protective measures or after-treatment. Formwork must be handled according to generally acknowledged rules of technology. A prematurely applied surfacer serves as an after-treatment for fine repair mortar.

CE Labelling
EN 1504-3
CE labelling is based on EN 1504-3 "Products and systems for protection and repair of concrete load bearing structures – Part 3: Statically and not statically relevant repair”, defining the requirements for the repair products.
Products matching the above mentioned standards are to be labelled with the CE mark. Additional engineer standards are effective for the use in Germany in structural safety relevant areas. Conformity is documented by the Ü sign (Überwachung = supervision) on the container. Established by documented evidence of conformity 2+ with controls and tests on the part of the manufacturer and notified bodys.
