Tips for 4001 Waterbased Epoxy

Prevent Streaking
Because 4001 provides a wet look it can cause streaking if not applied correctly. keep the material cool and do not apply at the hottest time of the day. Also it is extremely important to maintain a wet edge. If the material is allowed to dry before the next roller pass is applied then you have the possibility of it streaking.
Prevent Whitening or Blushing of The Dry Material:
There are 2 causes related to the material turning white when wet. 1.Mixing, it is not mixed correctly so be sure your applicators understand the importance of mixing correctly when using 2 component products. Just because it is thin does not mean you ca use a stick to stir it, if you do be prepared to get white blush spots in areas that are exposed to water or MVE. 2. Potlife 4001 will still remain fluid after the potlife has been exceeded and the problem that this creates is that the applicator still thinks it is ok to use because it looks and smells the same. So to try and save on material they will apply it and sometimes it looks ok or other times it will turn white like when it becomes wet. DO NOT USE AFTER THE STATED POTLIFE!
Its Too Late I Already Have White Areas:
First , do not seal over white 4001 that has not dried clear, if you do chances are the sealer will prevent you from repairing the 4001 and removal will be needed. If it is do to poor mixing then take care and wipe down the area with xylene until the white goes away. Then lightly sand the area and re-coat. This will work to resolve minor problems like barely over the potlife or slight variations from the potlife and if the whiteness is caused from water coming from above (instead of below up thru the slab). If the problem is more severe then removal of the 4001 and then proper re-application may be needed.
I Love the 4001 but I Need a Matte Finish:
Apply a coat of 5400 Matte over it.
It is also possible to pre-wear the surface by using buffing machines and proper pads and this will also provide a matte finish.
I use the 4001 as a Primer For Other Systems:
4001 is often used as a primer below finish resins, microtopping's or other clear sealers and it works great when used correctly. It is very important to apply the material over the 4001 shortly after it has set up and within a few hours of it drying. If you wait too long to apply the next layer over it then you risk the chance of the 4001 becoming a bond breaker. This is due to its high hardness and most material will not bond well to it. If the 4001 is very hard (check by using a fingernail, it will be difficult to scratch) then you will need to re-apply. If it is longer than 24 hours then it will need to be lightly sanded before re-application of 4001.
