Drying tests: actual sire. K3USS PAINTS dry faster! Drying tests, under controlled temperature and humidity conditions, of four sets of house paints-- three national brands; one made to Federal specifi cations--prove conclusively that paints containing white lead dry faster! Especially in humid, dusty environments where prolonged wetness picks up damaging dust par ticles and debris, house paints with white lead in their formulations dry set-to-touch three to six hours sooner than lead-free paints. 20 --------------------------------------------------------------- --- 7ew>prarv'e 50F-8*lobv H^rradity 75% -- lead 3cs 1_ 15 i l*od Fre* mk r>f!i T*mp*fatuf T7F-Re!ofi,* Hvmtdiry 50% l*adftc*|!!| lecd o X i 10 a cjrw r / : P-; a ;. c Jr/-; v.sc t-;v rt : ' | '> r-5| ; l/k, */,\l 1/5 1^-1 i;.; ptri B 11 ib ip B I8l| IB II 11 ii IfestnlV> IK 4 % 'x 4 \' { '' ' BC D Ab Manufacturer "LEAD" LENGTHENS THE LIFE OF PAINT BECAUSE: ;. ` ; i: i |i t. i |, I- . ;. : p.

' It Improves Appearance..-by controlling chalking and inhibiting mildew. .. The graph speaks for itself. The figures, taken from a standard, generally-accepted, stylus-type drying recorder--and confirmed by duplicate tests in separate laboratories--show clearly how white lead shortens the drving-time of house paints. "Lead" base and lead-free house paints, all mixed the same day, were applied to test panels to a thickness of three mils. Three paint manufactur ers, (A, B and C) each supplied a set of two brandname paints--one "lead" base and one lead-free-- for the tests. The fourth set (D) was made to Federal specifications: TT-P-102 {"lead" base), and TT-P-103 (lead-free). Two separate tests were made under different atmospheric conditions (warm and dry; cool and humid). These are valid reasons for the use of lead pigment in your paint formulations ... all valid sales argu ments.
