Method of Application
All Chemsol Products are recommended to be applied only by Approved Applicators and should be handled after using proper PPEs like Gloves, mask, goggles, etc
Substrate Quality
Ensure that the concrete substrate has a minimum compressive strength of 250 kg/cm2. The CDS (clean, dry, sound) test must be conducted before application of primer/scratch coat to the concrete substrate. The substrate must be free of all contaminants such as dirt, oil, grease, coatings and surface treatments, etc. Consider applying a test area if necessary.
Application conditions
Substrate temperature: 10-40°C
Substrate moisture content: Chemotec EIPN can even be applied on substrates with high moisture content like 10 days old concrete but ensure that the water is not ponded on the surface.
Relative humidity: 8o%max
Note: The substrate temperature must be at least 30 °C above the prevalent dew point temperature to reduce the chances of condensation on the floor.
Substrate Preparation
Mechanically prepare the concrete substrate to achieve a concrete surface profile between 3-4CSP this will also aid in removing weak concrete and cement laitance. Suitably established methods like grinding, abrasive shot blasting, etc., should be employed to achieve the same. Scarification is not recommended. An anchor groove of 5mm depth is recommended every 2 meters and on the periphery. Fully expose the blowholes and voids and repair them using appropriate products like Chemprime, Chemseal, etc. Remove oils, grease, wax, etc. by using detergent, low-pressure water, steam, or suitable chemicals, as they create a hindrance in developing a strong bond between the concrete and Chemotec EIPN.
Prime the surface with a 0.5 mm scratch coat of Chemotec EIPN. Priming can also be done with Chemotec EIPN LV primer. Chemotec EIPN should be allowed to flow and fill the anchor grooves while doing the scratch coat. Your Chemsol solutions expert will choose the suitable primer depending on the substrate condition. Identify and treat the expansion joints properly. Refer to the method statement for doing the same.
Mixing and Application
Pour Chemotec EIPN [R] into a 20-liter bucket and add Chemotec EIPN pigment paste to it. Stir with a helical paint mixer for 1 minute, now add Chemotec EIPN [H] and continue stirring for 1 more minute. After this, add Chemotec EIPN aggregates and thoroughly mix for 2min. Always mix complete packs, never split packs. Note that Chemotec EIPN aggregates are specially formulated reactive materials, and their quantity should not be altered to adjust the viscosity for workability. Visually ensure that the mixture has become homogeneous.
Immediately lay the mixture on the floor and spread it with a notch trowel/ pin rake to the desired thickness. Use a spike roller immediately (in less than 2min after laying) to deaerate the coating. Adhere to the following curing schedule before bringing the floor to service:
Curing Schedule
| Temp. (°C) | Foot traffic | Full cure |
|---|---|---|
| 10°C | 24 hours | 7 Days |
| 20°C | 24 hours | 5 Days |
| 35°C | 16 hours | 4 Days |
Cleaning of Tools
Clean all tools and application equipment with thinner PT 36 immediately after use. Hardened and/or cured material can only be removed mechanically.
Packing
Chemotec EIPN is available in pre pre-weighed kit consisting of Resin, Hardener, Aggregates, and pigment paste.
Handling & Safety
Keep the containers tightly sealed when not in use. Avoid skin contact and inhalation of fumes (if any). While spraying, it is advised to wear a mask. If it comes in contact with the body, wash affected parts with plenty of water. In case of persistent irritation, contact a physician.
