Can C2M be brush, sprayed or rolled?
Maxon C2M can be applied using a sprayer, brush, or roller depending upon the application tools available, substrate, volume of surface to cover, vertical or horizontal surface, hard to reach areas or unique thickness requirements. A light application of water could be applied to the area in hot conditions but if sprayed it is NOT mandatory because of a high volume, low pressure sprayer (15-80psi) rebound or splash back should be minimal.
What is the best preparation system to follow before applying C2M?
• 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 petro-chemical substances
I have flash rust on my surface, can I still apply C2M to it?
Application 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.
What is the mix ratio for C2M?
The ratio between Maxon C2M Powder and Maxon C2M Emulsion is essentially 1 to 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.
What happens if I encounter mud cracking in my C2M application?
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 to 1 ratio (emulsion to powder) and apply an additional coat.
Do I need to sieve C2M before mixing? If so when is it needed?
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 with 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.
What is the proper procedure to follow when spraying C2M?
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 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.
What are the proper points to follow if brushing or rolling C2M?
The applicator should treat the brushing or rolling of Maxon C2M the same as a latex paint when it comes to consistency when mixed properly. When brushing on a vertical surface, there should be virtually no liquid running down the substrate during a horizontal pass. Brush marks may be visible after the first brush or roller pass, but after a second pass the surface will be smoother. Brushed or rolled surfaces will not have as glossy a surface as a sprayed application. Continue to agitate the C2M solution during application. Let each coat dry completely before applying a second coat.
Is there anything that others frequently overlook when applying C2M?
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.
How do I mix the C2M? What is the best method?
For all application methods, the following protocol is advised: Maxon C2M Emulsion should be first 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 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, color and results.
Can you over mix the C2M?
Yes, if you over-mix C2M and introduce too much air into the mixture, it will harden prematurely.
How do I clean up my tools and equipment?
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.
Do I have to remix the C2M after the initial mix?
Only if the C2M has been sedentary for a long time.
Does the C2M come in different colors?
No
Does the C2M bridge cracks? Can I fill holes with it?
Generally, no, if the crack or hole is more than 5 mils thick C2M will mud crack. Small hairline cracks are not a problem.
When can I paint over the C2M?
A minimum of 24 hrs. cure time is recommended before painting
Can I add sand to it for non-skid?
Yes, however, the key is adding the amount of non-skid required and back rolling with C2M. It is always best to use a concrete paint as a top coat if the area is exposed to the elements, rain, water, etc.
Why would I put C2M over a new slab before coating it with an epoxy or other flooring material?
Before putting an epoxy, paint, tiles or Polyaspartic top- coat on a slab, it is typical to bead blast, grind, shot blast to provide a profile for the next coating. All these require time and costly equipment. C2M can be applied quickly and provide a strong substrate for your next product. Data regarding pull tests are on the website. All you need is a clean, dust free surface on the slab.
Is the C2M flexible?
Yes, C2M is bendable up to 90 degrees.
Can I add water to the mix? Acetone?
C2M liquid carrier is a mix of several products and will not tolerate thinners, acetone, or additional water. Both the powder and the liquid are factory formulated for the best possible outcomes.
What type of spray equipment do I need?
Conventional spray equipment, low to moderate pressure depending on the job site, tip 517 to 519 is average, find the spray pattern best for the job. C2M is heavy and over sprays will not carry far in the wind. Because of the hard and powerful aggregates in the powder, the orifice will need to be replaced is used for larger jobs.
What type of tip and spray pattern is best?
17 to 519 is average. 10-14-inch spray pattern is beat (25.4 to 35.56 centimeters)
Will the aggregates in the C2M harm the tip?
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 size 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.
Can I use the C2M as a bonding material between the original concrete and the new patching concrete?
YES. One of the best aspects of using C2M is its ability to act as a bonding agent over cold joints and for patching. Please check our website for more test results and details.
Is C2M a good product for spalling repair?
YES. One of the key features of our spalling repair protocol is the C2M. Cleaning lose rust off the rebar, and applying CRS is the first step. Second step is to apply C2M to the rebar coated with CRS and the surrounding damaged concrete before the patching concrete is applied. This allows the patching concrete to have a new and strong similar product to bond with. Lastly, cover the cold joint with C2M. A complete spalling protocol is available on our website.
Will C2M stick to rebar?
YES. C2M means Cement to Metal. That is what it has been designed to do.
Will C2M stick to FRP Fabric Reinforced Polymer structural material?
YES. Because the resin on FRP is so smooth there can be issues in applying paint. C2M will provide a strong and cement base substrate that is perfect for any topcoat.
