COMPETITIVE DEEP TINT FUT MALL PAINTS
Products from 14 different companies in deep tint flat wall paint quality hare recently been examined at this laboratory. The attached table shows the comparative performance of these paints and of our own deep tint flat wall paints. For this evaluation small brushouts were made of each of the paints on a primed wall board,
1-1/2 x 3-1/2 feat. An 8 minute lap was made in the center of each panel, Brushouts of this size pick up only large differences or deficiencies, and it is therefore to be expected that some of the paints receiving a good rating in this evaluation might look inferior
when applied to a large wall area,
'
Slight evidence of color streaking was observed in only
one paint,., "Wall-Fix'5 Deep Blue, In many instances, however, very
serious color differences were observed at lap points<>. This lap trouble
and the poor hiding, often found in the redjand the maroons, are the
two chief causes of poor appearance in one coat systems. All the
paints showed at leapt some "shiners" at the lap points, Paints which
showed differences in color at lap points or excessive shiners, also
looked bad when applied in two coat systems,
Ben Moore, Custom Color Corp. llason, Elliott, Felton-
Sibley, Baltimore Paint, and Hydall products have film textures similar
to our 47 F Xafc. The other products mentioned in the table develop
smoother films (similar to our deep tint flat wall paints) and con
sequently have better mar resistance. The best offthe competitive
products are made by Fuller, Obrien, Martin Senour, (Hidden and Great
Lakes, Sven in this last group there are great differences in quality
from color to color,
We conclude from this investigation that' our deep tint
flats as covered by Release Letters #1184 and Supplement #ll84-A, are
as good as the* best of the competitive products and better than most
of them.
