Roll On Rock® System 4h

Roll On Rock System 4h

Price:
Price for 4h is about 30-40% more but you have to remember that it also includes a primer coat which our system 2 does not. This will add build to the system as well as prevent the chance of holidays to to suck out of the epoxy into the concrete. 30-40% more is well worth it since you can put down a better system, do it in half the time so it doubles your production and probably your territory while reducing the inconvenience to your customer.
Concrete Profile:
Aggressive concrete preparation is not needed with this system. This is because the 5205 wicks into the concrete. Start with a clean porous concrete surface and grind the concrete using a 7-inch or larger grinder with a diamond grinding wheel to achieve a concrete texture similar to a 150 grit sandpaper. As a general rule an average 2 car garage should take about 30 minutes for 1 man to do. Do not acid etch period. Do not grind or shotblast unless there is an existing sealer or bond breaker present.
Holidays:
Another benefit is that the bodycoat will actually pull the flakes down which causes them to lay flatter (much like the system 1) and because of this the topcoat looks like it has more build since there is less surface area.
Extra Build tip:
5205 is great as a first topcoat over the flake when you want to create extra build, the reason is that you can apply it thinner so it seals the flake (Prevents the 5073 from diving into the flake) and it is dry in 20-30 minutes so you can put a coat of 5073 on top and all of it will remain on top since the flake is already sealed. This saves money for the 2 coat installer because the 5205 is less expensive, covers more and dries extremely fast.
How to Get The Most Potlife:
First, do your best to keep materials cool. Heat is the worst enemy of long potlife so don't leave it out in the sun on the driveway or in the truck bed. Unlike epoxy, all products used in the system 4 will have a longer potlife if left in the pails after being mixed. So on a typical 2 car garage you will find that it is broken up into 4 sections because of expansion joints or saw cut control joints. Start by pouring material out of the container in a fluid line on one section. Then begin to spread the material out so it covers that section. When section is covered be sure to backroll it at a right angle of first coat so the material is a uniform thickness (especially important when using the extremely glossy 5073 topcoat). Then proceed to do this process all over again on the next section, always working from material in the pail.
Touch Up a Holiday Where The Flake Did Not Hold:
This will not be an issue with experienced installers but if you do get a holiday where the flake does not cover then go ahead and use the 5205 and apply it very tight to the surface that needs more flake. Then sprinkle a very small amount of flake onto it just so it blends in to the rest of the area. DO NOT OVER FLAKE! This is the biggest mistake people make and it will be noticeable. Look at the touched up area from other angles to be sure it blends in. Allow it to dry 20 minutes then do a light re-scrape. Now your floor is ready to be sealed.
5073 Topcoat Tips:
Work the material as listed above in the how to get most potlife section. The biggest thing to stress is uniform thickness. By using an 18 inch roller you are spreading the material more evenly since there are 2 pressure points be applied to the roller (the left & right side). Also be sure to cross roll all sections before proceeding to the next section. Watch for low spots or puddles as these will become shiners (round glassy areas that are noticeable). If applying another coat after 24 hours then be sure to lightly sand the surface to de-gloss it. 5073 Tip Guide can be accessed by clicking here 5073 Rolling Techniques
New Construction Selling Point:
On most new developments the garage floor option is the last option to be done so it is usually done a day or so before the close of escrow. With most systems you have to wait 2-3 days before being able to use the floor. That is not the case with system 4, they can put it back in use the next day which means the development can release the property a day or 2 early which saves them interest and it reduces the chance of call back since the floor will be ready to take wear from other subs doing clean up.
Chip Profile
The chips will tend to lay flatter in the 5210, creating less surface profile when applying your clear topcoat.
