• Remove all loose debris using a hand pump, spray on degreaser over the entire area
• Let sit for 5 minutes (allowing degreaser to sit for longer will NOT increase effectiveness)
• Completely rinse degreased area 2 times
• Let dry for 30 minutes before any further application
• With extreme surface dirt or oil, you may have to apply a second time
• You must repeat this process until the substrate is free of any petrochemical substances

Application of C2M over flash rust is normal and acceptable for C2M if any flash rust is completely covered, and none is visible. If applying multiple coats of C2M, previous coats must be completely dry before a subsequent coat is applied.

The ratio between Maxon C2M Powder and Maxon C2M Emulsion is essentially 1:1 for spray applications. However, brush and roll on application methods will require slightly different mix ratios and application techniques.

For brush or roll-on applications, a mix ratio should include slightly more (10-30% depending upon conditions, substrate and desired result) Maxon C2M Powder for each unit of C2M Emulsion.

Using any application method, to avoid mud cracking, do not use too much material on a single coating. Instead, use less material on more layers, and make sure the previous layer properly dries before adding a new layer. If mud cracks develop, simply wait until the coat dries. Then re-coat the surface with a 1:1 ratio (emulsion to powder) and apply an additional coat.

If the applicator is spraying Maxon C2M, it should be sieved before application. This removes any particulates which might both prohibit a consistent finish and remove any particulates which may jam the applicator’s spray gun. The size of the sieve should be proportional to the nozzle size of the applicator spray gun. All spraying equipment must be cleaned. If there is any break in the spraying procedure, water should be immediately used to clean the nozzle and hose.

During the application, there should be approximately 6 to 12 inches between the tip of the spray gun and the substrate – depending upon the spray equipment and substrate. Adjust the spray gun valve so the gun is spraying a 6-inch fan, using minimal pressure. A 50% overspray technique is recommended. For optimal results, a dual coat program should be applied. First spray one coat horizontally across a section, and then complete the process next with a horizontal spray direction. Do not spray at higher pressures than recommended above, as the mixture may dry before landing on the substrate. It is an acceptable practice to brush hard to reach areas after spraying. Continue to agitate the Maxon C2M solution during application. Let each coat dry completely (to touch) before applying a second coat.

All spraying equipment must be cleaned. If there is any break in the spraying procedure, water should be immediately used to clean the nozzle and hose.

Ensure proper coverage on edges, as during normal hydrolysis-induced cure, the material may become thinner than expected. Make two vertical passes on edges, and then finish with a horizontal cover to ensure proper coverage and that enough material is in contact with the substrate.

For all application methods, the following protocol is advised: Maxon C2M Emulsion should first be added into a clean container. Maxon C2M Powder should then be slowly added in the appropriate ratio, so the fines of the powder are not dispersed in the air. Mix 1/3 of the C2M Powder and stir until the product looks consistent. Continue adding 1/3 of the powder and re-mixing until the entire Maxon C2M Powder has been introduced into the Emulsion. Mix each step for at least 2-3 minutes rotating the mix so that all areas of the container are free of clumped powder and the material should look consistent. Before putting it into the spray unit, the material shall be sieved using a mesh screen to remove any hard particles that may foul the spray equipment. It is recommended that the applicator sample the mix on a non-critical asset before application on the desired asset to ensure mix consistency, colour and results.

Yes, aggregates will harm spray tips; aggregates should only be added to C2M right after it is applied while still wet.

The aggregates in the powder/cement portion of the C2M are very sharp and tough. These aggregates are very small and will not be easy to distinguish in the powder before or after the liquid is introduced.

These aggregates come in several different sizes and shapes and fit together with the cement mixture to provide the client with an exceptionally tough and flexible coating.

Over time the tips will begin to show wear and tear and will need to be replaced on the job. When you see an ineffective spray pattern, it is time to change the tip.
