Management i asked to decide if the sale of the 387-Msw of Vinyl Hwofiry Paints, whose performance has been generally inferior to rointauM expected performance lewis * should he di* eoatintsed by Expert Sales and replaced by sals of the proposed line of scry lie emulsion paints, whose anticipated improvement in resistauce to the effects of efflorescence has not yet teen fully established*, In consideration of this proposal the fol lowing point are felt to tea pertinents
Cl) 3 aery lie emulsion paints are not expected to prevent the - "efflorescence1 s of alkaline salt from .the concrete substrates. Being more alkali resistant than tha vinyl' emulsion paints they are, however, expected to have tetter chalk resistance and color retention under these alkaline conditions,, louse . tests up to even months old in Puerto Eieo are confirming
this expected fNurfo&MQes*
(2) approximately 800 gallons of the proposed quality products
have teen used in Puerto Sieo by paint contractor in a trial marketing program., Customer acceptance of initial' properties
has teen well established, based partially m m average 25%
- increase in coverage compared to comparable vinyl masonry
product.
<3) - These products use RC-11005 B!10" acrylic latex whose supply

(4) Average mill' costs are about 7d/gal. higher than comparable Vinyl Masonry products based-on current actual costs af'HC11005. Costs are.expected to te equal or slightly less when EC-11005 is produced at the Fort Madison facility.
(5) Reproducibility has not teen established on any one of the
. proposed products although the several 150 gallon batches md
one 500 gallon batch of four colors made last fall indicate
no unusual problems .

. Close observation during application Of spainfe cm eight of tte test houses showed that initial properties of ease of applica tion by brush and roller, gloss and color uniformity, appearance at
laps and touch-up properties are all very good to excellent and equal
to fete comparable vis^rl masonry product. Hiding is very good with
an gverdga-increase in square foot coverage of about 25% 0 M m ess-
ample, in one test tte white acrylic paint gave 370 sq. -ft./gal. eh first coat and 410 q. ft,/gal. On second coat, to 920 Whit Vinyl
paint gave 250 sq. ft./gal. on first coat and 340 mqc ft./gal. on
second coat. Both systems were rated very good, for hiding. Osi
another building where #657 Oyster White was applied''to all interior
and exterior walls,, only 17 gallons of paint were used whereas- ex
perience indicated that 26 gallons of 387-364 Vinyl dyster"White wonId. haws teen required, ibis property alone has created a ready
acceptance of this line of paints by the few contractors who have used it.
