Aggregate for PAP

5 replies [Last post]

There is an existing commercial office building with a brand new Terrazzo (epoxy/quartz) floor with some sort of very thin sealer, I'll guess an acrylic sealer, that's already looking scratched.  The building owner is considering a different topcoat.  I suppose a good plan of action would be to scuff (with 40 grit?) to remove the sealer and create a surface profile and apply two coats of clear PAP with the second coat containing an aggregate for anti-slip purposes.  What type,  mesh size, and volume per ounce of aggregate do you recommend?  Tabular alumina, Shark Grip, Shamrock Technologies, etc.?

THANKS!

If you have a brand new epoxy

If you have a brand new epoxy terrazo floor you would not cover it up with a pap IMO, thats just crazy. If their final sealer is comming of then something has gone wrong during the last stage of polishing. Just strip the sealer and insall a good qualitylitium based sealer. Installing a pap over a long lasting floor like epoxy terrazzo is not the answer.

i also believe using epoxy

i also believe using epoxy terrazzo can be crucial, i am also in the same doubt! whether to use it in the first place or go for the substitutes!

Epoxy terrazzo floors are

Epoxy terrazzo floors are very tough/durable if professionally installed, ground, finished (less labor intense than that associated with cementitous terrazzo).  As for applying PAP (polyasaprtic aliphatic polyurea) over industrial epoxy surfaces   ... PAPs (high gloss reflective image, no labor intense/costing ongoing waxing regimes, easy to clean/maintain/sanitize) are frequently applied as highly wear/abrasion, chemical, stain resistant, long lasting protective shield over commercial/industrial/instutional floors (epoxy/flake-vinyl chip floors, 3D image epoxy/metallic additive floors, seamlessly applied epoxy/colorquartz, and other 100% solids industrial epoxy coatings).

PAP can be, and has been, successfully applied over epoxy or cementitious based terrazzo floors so long as they are property profiled (high performance/high solids PAP will increase the degree of wear/abrasion, chemical, foreign matter resistance associated with epoxy based floors while providing lasting high gloss/reflective imag)e; however, epoxy or cementious based terrazzo floors can be restored to their original shine/high gloss reflective image by regrinding/polishing them if/when deemed necessary as part of routine restoration/maintenance procedures.

If you do opt to apply PAP over the epoxy/terrazzo floor you MUST of course strip the acrylic complete (as you well know) then profile mechanically.  One coat, having approximately 4-5 dry mils (see tech data/spec sheet of PAP that will show the sq.ft per gallon "dry mil" coverage rate, the high the solids of the PAP the higher the dry mil build will be). If you were apply Flexmar Coatings NextGen High Solids/93% (note: they are a valued DCF site Sponsors, see banner ad link) at 4 mils coverage would be 360 sq.ft. per gallon (at 5 dry mils 288 sq.ft. per gallon).  You can add a fine micro anti-skid media directly into the PAP/batch mix that will not sink or float for uniform ease in application and safety engineered traction (about 4 ounces of it per gallon).  NextGen High Solids has virtually no odor, is envio-safe/non-hazardous, 25 minutes open working time, dries in 1 hour, and floor can be returned to service/use 2 hours after it is dry (has many other highly sought after features/benefits).

I have personally worked with Jack Bracco/President and successfuly applied Flemar's PAPs since 2005 ... I'll be glad to promptly answer any questions/concerns you may have based on my experience and knowledge of them (feel free to give me a call on either my DCF direct line 254-212-5536 as shown on the top of all DCF forum pages or drop me a email message at your convenience Lindy.Ausburne@gmail.com).

I agree a pap coating on this

I agree a pap coating on this floor would be a total mistake. Just burnish it every so often to get the shine back.

I agree, as stated in my reply, and agreed to by professional's replying ..."epoxy or cementious based terrazzo floors can be restored to their original shine/high gloss reflective image by regrinding/polishing them if/when deemed necessary as part of routine restoration/maintenance procedures" ... PAP will bond to it so long as properly prepared and profiled; but, why do so when can just re-grind/re-polish in order to restore and revive it.
