Construction instruction of ADO 121 coating system

   1. Requirements:
1.1. Labor protection

– Workers are required to use all the necessary personal protective equipments including shoes, gloves, safety glasses, hard hats and work clothing.

 

 

1.2. Humidity

– Humidity level of concrete floor must not be higher than 6%.
– Humidity of air must not exceed 90%.

 

 

 

   2. Mixing materials
2.1. Mix the PrimeSEAL PS60 (PS50) lining including two components A and B

– Pour component B into component A and mix well for three minutes (may take longer depending on weather conditions and machinery …)

 

 

 

 

 

2.2. Mix the Epoxy KeraSEAL ADO121 paint – including two components A and B.
– Using a mixer, mix A for three minutes (may take longer depending on weather conditions and machinery quality …)

– Pour component B into component A and mix well for three minutes (may take longer depending on weather conditions and machinery …)

– Can mix up to 5% more of the solvents to facilitate the construction process.

   3. Steps of constructing coating system – 1 lining and 2 coating layers.
3.1. Hygiene and surface treatment

– Ensure the surface is free of dust, dirt and grease.
– The surface is roughened by special machine with suitable sandpaper.

 

 

 

 

 

 

3.2. Apply the first layer of KeraSEAL ADO121.
– Spread the mixed KeraSEAL ADO121 material the area that is to be constructed with a short haired roller.

– Apply roller in many turns and in two perpendicular directions, ensuring uniform coverage of the layer.

– Finishing the process, make sure the layer completely cover the lining layer and be relatively uniform in color.

– Let it dry for at least 8 hours before proceeding with the next steps.

3.3 Apply the lining layer of PrimeSEAL PS50 (PS60)
– Use a long-haired roller to spread the PS50 (PS60) mixture on the surface

– Applying roller in turns to ensure uniform coverage of the layer.

– Do not apply too thick lining which will cause cracking and blistering of the surface.

– Let it dry for 8 hours before patching or applying the basecoat of Epoxy KeraSEAL ADO20.

– Supervisor must record the rate of mixing and batch number of materials in each construction day.

 

 

 

 

 

 

 

3.4. Apply the finishing layer of KeraSEAL ADO121.
– After the basecoat has completely dried, the pockmarked areas on the remaining surface should be covered with KeraCrete NS50 glue.

– After the patching positions are dry, apply 1 coating layer on these positions to ensure color uniformity before applying the finishing paint.

– Using a scrubber with suitable sandpaper, rub on the entire surface of the first coat to create roughness and remove impurities.

– Spread the mixture of KeraSEAL ADO121 materials mixed on the area to be constructed with a short hair roller.

– Apply roller in many turns and in two perpendicular directions, ensuring uniform coverage of the layer of materials spread on the surface.

– The coverage, uniformity in gloss and color must be ensured.

– Let it dry for at least 24h before operating gently above and 72 hours when using.
