Ecodur 201M: Manual Floor Coating Instructions


Safety glasses, gloves, and protective clothing must be worn at all times. Gypsum and castor oil in the Part A mix will separate over time.

Ecodur 201M Storage Recommendations

Part A:

1. It’s recommended that Part A be stored at room temperature. No less than 32°F (0°C).

2. The Part A bucket should be stored upside down for ease of mixing when used. Flip over several (min one day) days before use.

Part B:

1. It’s recommended that Part B be stored at temperatures between 75° to 105°F (24° to 41°C).

2. Product must be kept free of moisture. Keep container closed because the product absorbs moisture from the air over time. Moisture in the product causes it to produce CO2 gas which may cause pressure build-up inside a sealed container.

It is important to ensure Part A is fully mixed before adding the Part B to it.

Ensure your Ecodur 201M coating material kits are kept at room temperature prior to mixing. Cold material is hard to mix and work with. Hot material may cure too fast.

Remember to Mix Part A Well.

Paint Shaker_sm

1. Put Part A into a paint shaker to aid with the mixing process. Then mix the Ecodur 201M coating material Part A container well with a suitable mixer such as those used with heavy duty hand drills for mixing small batches of masonry or mortar.

2. Check to ensure that all gypsum pieces are mixed in once removed from the paint shaker. Mix until there are no lumps and the bottom of the container has been reached. Use the metal mixing blade and tap on the inside walls of the container including corners where the container bottom meets the container sides to be sure.

Adding & Mixing Iron Oxides (Optional)

1. After mixing Part A well, pour the pre-measured iron oxides into the Part A bucket.

2. Mix until there are no iron oxide lumps and the bottom of the container has been reached. Any unmixed iron oxide will result in unwanted streaking and color issues. It is best to allow the iron oxide a “wet time” to soak into the Part A. Best to mix and add the iron oxide at the start of a job to allow an hour or so of soak time. Then fully mix again.

Do not worry about over mixing of Part A. It is important not to have any gypsum clumps in your mix due to incomplete mixing. This will affect your mix ratio.

1. After completion of Part A mix, add entire Part B material from jug into the premixed Part A container.

2. Mix Part A (white) with Part B (brown) until Part A and Part B are fully mixed together.

3. Once Part A and Part B are fully mixed get the coating out of the bucket by pouring onto surface. Do not leave bucket standing upside down on the surface being coated.

Be Prepared to Coat

4. You will only have 30 to 40 minutes (See curing estimates chart) to apply your coating material (after Part A and Part B are mixed together) to the surfaces before the coating material starts to harden.

5. In order to begin coating, the substrate must be dry which is generally not achievable without having the dew point temperature being at least 5°C or 10°F below the substrate temperature.

6. When you finish mixing the Part A and Part B, the pot life will be about a half hour at room temperature and a 24 hour cure.

Dispose of unused material as directed in MSDS.



1. After thoroughly mixing the Part A and Part B together start applying the mixed material to the floor. The mixed product is exothermic (ie creates heat while curing) so mixture needs to be emptied out onto surface being coated to avoid overheating and curing too quickly in the bucket.

2. Start by pouring the contents of the bucket on the floor evenly in the area to be coated.

3. Wearing spiked flooring shoes, use a squeegee or notched squeegee to evenly apply the Ecodur 201 to the desired thickness across the floor.

4. After squeegeeing the material use a 3/8 nap roller (an 18″ roller cover works best) and cross roll all the material that has been put down to ensure adequate coverage of the area. Use smaller rollers or brushes to “cut in” the tight areas (baseboards, stem walls etc.).

5. After an area has been poured, squeegeed, and rolled add the desired amount of flake (colored paint chips) and or non-slip grit to desired look and feel you are trying to achieve.


6. Wait approximately 24 hours (depending on temperature) for the Ecodur 201 to dry prior to top coating with the clear coat of your choice.

7. Applying the top coat can be done in the same way you applied the Ecodur 201 or by dip rolling. Just follow the manufacturer recommendations for the specific top coat you decide to use.
