Epoxy Flooring Tools Information

Epoxy Floor Coating Preparation


Floor Grinders: Floorex 480mm Grinder | Husqvarna 450mm Grinder | Scintex 250mm Grinder

Vacuums & Dust Extractors: Floorex | Husqvarna S36 (3 motor phase) | Husvarna S13 (single phase)

Diamond Grinding Plugs: Rectangle | Arrow | PCD (to remove previously coated or adhesives on the floor)

Redi-Lock Diamond Plugs: Sydney Industrial Coatings (9 pack)

Diamond Grinding Cup Wheels: 125mm to 250mm



  Step 2 

Polish the concrete using a higher grit diamond cup wheel

Ensure the floor is level and polished consistently to avoid grinding marks or imperfections showing in the completed application.


Diamond Grinding Cup Wheels: 125mm to 250mm



  Step 3  

(OPTIONAL) Repair cracks and imperfections using two-pack epoxy fillers

As this is a clear floor coating system, patching imperfections will be very noticable on the floor. It is completely up to the applicator’s preference as most prefer the natural look of the cracks and feel that the imperfections are what make the floor perfect for them.
Fill in all your cracks using a 2-pack epoxy filler and wait until the patching mortar is fully cured before grinding or coating the floor, this process usually takes a minimum of 6 – 8 hours.


For larger cracks and spalls: SIC Epoxy Coving & Repair Kit | Sika Sikadur 31 CFN

For smaller patching and cracks: Sika Sikadur 33 | Sikadur 513 (magic powder mixed into epoxy to thicken up)



  Step 4  

Apply the first coat to the floor and allow the coating to cure

General curing time (at 20°C) is a minimum of 8 hours. This can vary further if solvent has been added to the coating. General curing time (at 20°C) is minimum 8 hours. It is always reccomended to back roll the product against the natural light to assist with achieving a more uniform finish. Wearing spike shoes to walk over the epoxy can help ensure the product is applied evenly, however you must apply safety practices and be cautious of injury.


Aliphatic Polyurethanes: UltraKote UVSeal (Gloss only)

Waterbased Polyurethanes: UltraKote SuperClear (available in Gloss or Matt)

Waterbased Epoxies: EpiMax 999WB (comes in Satin or Matt)

Concrete Sealers: Sikafloor Duraseal



  Step 5  

Return within 24 hours to apply the second coat, apply as per technique from step 4

If this step if not completed within 30 – 36 hours (depending on temperature) of applying the previous coat, the floor will need to be scratched using an 80 grit sand paper.



  Step 6  

(OPTIONAL) Return and apply another coat as per above

If you are applying the system over porous concrete, a third coat may be required. If a third clear coating is required, repeat above.


Antislip media can be added to the topcoat to achieve a higher slip rating


Your floor will be trafficable after 24 hours and heavy items such as cars, boats or trailers shouldn’t be parked on the floor for 7 days after application of the final coat
