Asphalt Emulsion Proves Fine Side Line lor Lumber Dealers

Because it is generally conceded to be a "rqllacement" year, Western lumber dealers are reporting a wide sale for Pioneer Asphalt Emulsion in the coating of all types of roofing materials, is the statement made by Mr. J. H. Plunkett, general manager of the Pioneer Paper Company.

'One of the important advantages of the material for roof coating is the fact that it may be applied cold, thus eliminating the elaborate equipment which is essential for the use of other forms of Asphalt. Asphalt Emulsion forms an impervious surface that is unaffected by the elements, and it will not check nor crack, run nor sag, under any climatic temperature. It is suitable for the roofs of residences, business establishments, industrial buildings, warehouses, hotels, office buildings-in fact, for every type of roof.It may be successfully coated on composition .roofs, corru- gated iron, composition shingles, metal tile, asbestos roofs, and wood shingles. Where color is desired red or green Albikote may be used. In the case of metal roofs the matenal effectively seals out moisture, thereby preventing corros10n.

Following a discussion of the fa,ctors affecting grades and strength, some 50 pieces of lumber of sizes customarily used in construction will be placed on exhibition near convention headquarters, and building officials will have an opportunity to examine them at their convenience and estimate the grade and strength of each piece. On the last day of the convention the results of these individual estimates will be checked and attention will be especially devoted to a discussion of the grade and strength of those pieces concerning which the most errors are made. Several prizes will be awarded for grading judgment, one of them being a pair of candlesticks made from wood from the old roof of the White House at Washington, which was in place for 112 vears without deterioration.

It is pointed out by the manufacturer that every territory in the eleven Western states ofiers possibilities for the lumber dealer, in the sale of Pioneer Asphalt Emulsion, because of its exceedingly wide range of use and the utmost simplicity of application. This fact together with the approaching rainy season affords a timely sales suggestion, to create additional business for Western lumber dealers.
