CONSTRUCTION INSTRUCTION OF ADG20 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%.

– Construction site requires good ventilation.

 

   2. Mix materials:
2.1. Mix the PrimeSEAL PS60 (PS50) primer 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 KeraGuard ADG20 lining 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 primer 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 PrimeSEAL PS60 (PS50) primer

– Use a long roller to spread the mixture PS60 (PS50) on a clean surface.

– Applying roller in turns to ensure uniform coverage of the layer of materials spread on the surface.

– Do not apply too thick lining to create puddles that will cause cracking and blistering of the surface.

– Allow to dry for 8 hours prior to patching, surface treatment or subsequent operations.

– The pitting, cracks on the surface should be filled with KeraCrete NS50 non-shrink Epoxy glue.

3.3 Apply the first coating layer of KeraGuard ADG20

– Spread the mixed KeraGuard ADG20 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.

 

 

 

 

 

 

 

 

3.4. Apply the finishing layer of KeraGuard ADG20

– After the first coat 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 coat of paints 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 KeraGuard ADG20 material was 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 dry for at least 24h before operating gently above and 72 hours when using.
