Tips for 5073 Fast Drying Polyurea

5073 Polyurea

Extra Build tip:
5205is great as a first topcoat over the flake or other absorbant surface when you want to create extra build, the reason is that you can apply it thinner so it seals the surface (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 ontop 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.
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 12 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
5073 Reported Problems Due to Unique Application Techniques:
2 Quick Thick Coats. If you try to do 2 thick topcoats quickly that you can get solvent blisters or other film defects due to the blocking of solvent release of first coat. Allow the first coat to dry completely before applying second coat. Remember this material is designed to stay open in mas so if you put it on real thick it will take longer to dry, hence the long potlife when in the container. Try using a tight coat of 5205 and then topcoat that with 5073 30 minutes later, this should give you the build you are looking for.
