Best Practice High Performance High Build floor coating application

Tools Needed

Depending on the area size,

Either diamond floor grinder or  hand held diamond grinder- industrial vacuum- slow speed mixing drill- plus appropriate extension cables, brooms, scrubbing brush, good quality, masking tape, medium pile roller sleeves, roller frams, paint scuttles, paint brushes, pallet knife, trowel

 PPE needed- dust masks, safety glasses, gloves, knee pads

PREPARATION & APPLICATION

·         Keep all products inside the building at the working area temperature as soon as arrival. 10°C to 15°C

·         Sweep clean the area free of all debris

·         Locally de grease any oil / grease spills. Scrub wash & dry prior to grinding.

·         Diamond Grind using a Floor sander , Hand held grinder or larger DFG 200 or similar make Diamond floor grinder. Grind the entire area to remove all  dirt & surface Laitance.              Shotblasting can be used on larger areas but it tends to leave minor pitting & track marks visible in the finished High Build coating.  

·         Grind the substratete clean. Be sure to remove surface laitance & any loose flaky paint. All grinding machines should be connected to a Vacuum.

• Thoroughly vacuum (twice if necessary) the area to ensure there are no loose particles and surface dust.
• Inspect the clean floor for any Cracks/ poor joints/ frail areas/ bolt holes & the like. Make the repairs as appropriate.  (For deep Cracks >5mm) use Resin Crack repair or deep fill resin mortar for repairs < 5mm other use Fine Filler P38).
• Grind all the patch repairs smooth & flush

·         Set out a mixing station outside the working area, if possible protect the base with thick Polythene & hardboard floor protection.

Ensure all products are side by side Part A (base) by Part B (hardener) 

Try to use the mixed product within 20 to 30 minutes to avoid it becoming gel like. 

At all edges & stop points fix strong adhesive masking tape edge protector to guarantee the straight finishing line. Press out the tape with a clean dry roller to ensure the are no air voids to remove the bleed risk.

Step 1- Mix base A (colour unit) to blend the colour together. Mix for 3 minutes using a slow speed mixing drill & paddle. 

Step 2- Pour all of hardener B into the part A container. Allow to fully drain out. Mix together for 3 minutes until fully blended. 

Step 3- Pour approximatly 50% of the product into the plastic paint scuttle container. 

Step 4- Carefully cut in the edges & other floor extrusions using the small paint brush. 

             At the same time & keeping in line with the cutting in, roll out the product using to medium pile roller. Apply product evenly, ensuring to cover all the base, always keep a wet                 edge. Once the first rolled out section is completed, cross roll over again using a dry roller. This will remove any excess & lines, leaving a consistent finish. Remove any         edge  tape if accessable. 

    Step 5- Allow minimum of 12 hours to dry, test with your hand to ensure the floor is fully hardened before the second coat application in the same method.

     Apply a further coat in the same method of the superior resin store High Build Epoxy. Remove edge tape

For machine movement on the finished floor. Firstly, allow it to fully dry for 24 hours minimum. Where you are moving any heavy equipment place clean new floor protection or thick gauge (1200) polythene. Prior to movement to avoid scratches.

• For the Yellow lining, decide on the Line width & fix good quality (no bleed) tape in parallel lines. Apply the Yellow High Build by brush & carefully remove the tape after approximately 2 hours.

A few simple steps to help you with best practice in application are.

• Prior to commencing the application,  place all products together.  All base A with hardener B, on the protected mixing area. Be sure everything matches before commencement. For example, 5 x Base A High Build  with 5 x Hardener B High Build.
• Ensure to mix each unit correctly. Using a slow speed drill & paddle, mix the base A alone to disperse any colour separation. Add all the hardener into the base & mix for a full 3 minutes. Pour into a scuttle. Do not leave for more than 10 mins in 10kg volume.
• Once mixed, start & continue until you have 100% completed an area, or up to a masking tape line. Never stop part through.
• Never either cut in or not cut in the edges on a standalone operation. Always cut in at the same time as the roller work to keep the application of brush & roller at the same time.
• Roll out evenly on to the floor & cross roll in the opposite direction to ensure the application is even. Roll in straight lines. Careful not to spray the product on any machinery. Roll out slowly.
• Always work to tape lines, never just uncontrolled random roller, or brush applications.
• Never empty the mixed product bucket upside down to drain on the floor.  

Suggested Plan for 3-person team if 100% of the area is to be done. On smaller area, it’s possible to complete the preparation & priming/ first coat in one day.

222m2 typical area whole area Plan

-DAY 1 preparation: 1 person on edge work & 2 people on big machines. 1 man removing dust bags, arranging vacuums & keeping leads tidy

-DAY 2  for primer ( if required)

-DAYS 3 & 4  for two colour coats of high build

Allow 5 days including 1 day untouched drying time,  

 The programme will be continuous if the temperature inside the building is 15°C & rising & there are no obvious drafts.

The substrate should be kept at 3°C above dew point whilst in application & 1 week after completion. 

Usable Pot Life @ 20°C = 20 minutes maximum

Tack Free (overcoat time) @ 20°C: 8-12 hours (overnight)

Hard Dry Time (for client use) @ 20°C = 24 hours
