Epoxy mortar system KERACRETE RM120

1. Requirements:

1.1. Requirements for labor protection work

– During application, workers must wear full labor protection (hat, clothes, shoes, glasses, mask, and gloves).

1.2. Requirement for moisture

– Substrate moisture content < 6%.
– Maximum relative air humidity 85%.
– Min. substrate temperature 13ºC.
– Max. substrate temperature 39ºC.
– Construction areas require good ventilation.

2. Mixing:

2.1. Mixing KERASEAL PS60

– Material includes composition A and composition B.
– Use specialized mixer, approx. 600 rpm with a suitable mixing paddle.
– Add the composition B to the composition A and mix a further 3 minutes until homogenous (may take a longer depending on weather conditions and equipment).

2.2. Mixing KERACRETE RM120

– Material includes 3 components: Composition A, B and C.
– Add the composition B to composition A and mix a further 3 minutes, leaving for 2 minutes. Then, add composition C and mixing mixture for 1 – 2 minutes.
– Mixed material is homogeneous, no clot and deposit.

3. Application steps

3.1. Surface cleaning and treatment

– The surface ensures no dust, dirt, oil and other impurities.
– Remove weak adhesion on the surface to be patched and repaired.

3.2. Mixing KERASEAL PS60

– All positions applied KERACRETE RM120 must be primed with KERASEAL PS60 first to increase adhesion between material and concrete surface.
– Do not apply primer too thick or to create puddles will cause cracking and blistering.
– Allow to dry 6 hours before applying patch sealant on top.

3.3. Mixing KERACRETE RM120

– Use a steel trowel or putty to fill the material in the position to be applied. It can be filled several layers for maximum effect.
– Allow the sealant complete dries before applying the next sealant or topcoat.
– Allow to dry at least 8 hours before applying the next steps.

3.4. Notes during application

- Because the curing time of the material is very fast, it is recommended to note that the mixing volume should be applied in a short time to avoid waste.
- Allow to dry at least 8 hours before applying the next steps.
