RHODE ISLAND ----________ -- This report covers inspection on June 7th, Sth and 9th, of 6 houses in the New Bedford, lass. area 5 houses in the Providence Rhode Island area and 1 house in the Boston region which ted been painted with 603-901 Colonial Red House Paint This is a continuation of the inspections reported in Memorandum Report $3-493 dated 8/11/52 1 Durability of 603-901 Colonial Red is outstandingly better than orthodox type red House Paints or Bam and Roof Paints. This applies to color and gloss retention as well as film integrity 2 Gloss retention on the northern and protected exposures is excellent. In fact the gloss remaining after 4 years is est imated at 70 - 80% of the original gloss Unless special pre cautionary measures are taken, such as sanding, wire brushing or the like poor adhesion of subsequent,topcoats may be experienced* 3 Where no blistering difficulty was encountered within a short time after application (so called solvent blistering) the occurrmee of blisters appears to be no worse than with conventional type house paints However, two of the houses inspected are be lieved to have experienced ''solvent blistering-' and one subsequent formal complaint (believed to be solvent blistering) has been received from Boston Region* In view of this, it appears that more extensive trial marketing experience should be obtained in Southern Regions before divisional release of this type House .Paint in order that a more precise definition may be obtained on the risks involved* Solvent blistering appears to bathe last stumbling Cn^n^vmS fIfcM3r,dnTiTiKna\releaSe f aik7d- ^K^dy colors.

House'of Dr. B&vid Rom {Base, owner as above) > ., -- This s the first inspection of this house* the in spection being prompted by a complaint f blistering. Identity of the first or prime coat applied Is not known* although it Is believed to hay been a coat of tinted House Paint Primer or a .a; coat of #160 Scotch Gray House Paint. Topcoat was one oat of \~Uolnial Red Voiding and #40 O.W. on windows and trim. Qbaer 5 vation revealed that previous blistering had been encountered on ^ trim and siding and also that previous checking had occurred on the South Side. There were scattered blisters on the north* east* and H west sides of the house. These blister were random in site, the largest being approximately Zn in diameter. The. number of blisters observed on these areas was slightly greater than the number of blisters developed in previous coatings.' The south and south west sections of the house were remodeled at the time of the painting and no blisters or film failure of any type was observed over the new shingles on this section of the house. The garage is attached to the house and is unheated. The doors face north. The east side of the garage shows severe blistering and cracking at shingle' joints and the south side shows severe loss of gloss and cracking but only few scattered blisters. Microscopic examination of films from' blisters re vealed approximately 6 or 7 coats of paint (including most recent painting!. The blisters appeared to peel down to the initial . coat of paint on the shingles* which coat appeared to be very resinous and spongy in character and appeared to have had relati vely weak bond to the wood substrate. The elapsed time before the blisters appeared is not definitely known* but the blistering was reported within one month after application of the Colonial Red. Dr. Eos and his family were absent during August 1952 when the minting was done. This blistering complaint is thought to be caused by solvent or moisture vapor trapped In the wood when the painting was done and which produced blistering of the dried film when heat from the sun caused the solvent dr oisture t volatilise r expand. This is a recognised problem with alkyd type paints when applied during warn summer months and this complaint serves to emphasis the need for an improvement in solvent blistering properties of tills quality before expanded release is proposed.
