Preparation of surface
Wash the surface from easily removable foreign materials.
Curing
Wet the coated surface with water 6-8 hours after application.- Application Instructions
- KF-E-admix is an admixture to concrete, mortar and stucco mixes. KF-E-admix increases compressive strength, impermeability to liquids and corrosion resistance, with 2-3 times lower shrinkage. There are no cracks, flaking or sliding. Stable, permanent color will not fade.
- KF-E-admix PREPARATION
- Mix the KF-E-admix powder thoroughly before use in a drum mixer or in a high speed blender. This will re-homogenize the mix, as the contents can settle or segregate during transportation and handling.
- APPLICATION
- Prepare at least 0.5 m3 (½ cubic yard) of any dry concrete or mortar mix. Use Portland Cement Type I or II, and blend all the dry ingredients of the mix first for 10 minutes.
- The surface of the wall, floor, or pavement should be wetted before KF-E-admix application. Spray surface with water at 1 Liter per m2.
- Strew 3 Kg - 12 Kg KF-E-admix for every 100 kg of Ordinary Portland Cement type I or type II in the concrete/mortar mix. Mix it all dry for 20 minutes. Clean the mixer’s walls from any residual pigment.*
- Turn on the mixer and add water. Start with a water-cement ratio of 0.38. The less water, the better the results.
- Mix for 5 minutes. If the mix is still stiff, add 0.25 Liters (1/16 GL) of water while continuing mixing, until the mix is workable and creamy. The "creamy effect" is a sign that mixing is complete and the product is ready for application. Application on walls should be done with standard stucco technology.
- CURING
- Spray the surface with water 10-12 hours after application, until the surface is slightly wet (without any remaining water spots).
- Please watch for any possible water spots and wipe them off with a mop immediately.

Safety & Health
- Safety
Operation with KF-E is similar to cement mixing and finishing jobs. Always use an approved respirator and rubber gloves. In case KF-E is inhaled or gets in contact with the eyes, rinse and wash abundantly with water. KF-E is non-toxic, non-flammable and non-explosive for transportation and handling.
Packaging & Availability
- Availability
There are three types of KF-E available for different application requirements: KF-E-coat (cement-based paint), KF-E-hard (curing & densifying topping), and KF-E-admix (admixture to stucco/mortar mixes).
