Mr. Greenhouse Man 



Have you covered your 

 brick boiler settings with 



Yils^plf^sH 



SEALER and started 



€L8tlC SAVING COAL? 



Get Busy -jthe infiltration of cold air through cracks and poroused 

 bricks means that you must burn more coal to get the required amount 

 of steam. 



Your boiler is drawing in all the cold air possible, in the same man- 

 ner that a vacuum cleaner draws in dirt. 



Stop this infiltration of cold air once and for all. 



" Seal the air leaks in your brick settings," says the National Fuel 

 Administrator. Cold air will never make steam. This is considered 

 the source of the greatest loss of fuel that is known to science, and the 

 easiest one to remedy. 



VP SEALER is a

_ L 1^^ _^^ I ^. ^^ I* "« ^m, cement, composed 

 ILCIPICISLIC ^iff^ra'/m^fd 

 IL with asphaltum 



gums. The asbestos is so thoroughly intermixed that after setting up, it 

 forms an indestructible blanket over 

 your boiler setting, expanding and 

 contracting with the brick work, 

 stopping all further cracking and 

 disintegration of the mortar. Anjr 

 one can apply VITAPLASTIC 

 SEALER. It spreads easily and 

 rapidly with an ordinary mason's 

 trowel. 



VITAPLASTIC SEALER can be applied 

 while your boiler is in operation; in fact, when 

 you have steani^p, and the bricks are warm, the 

 sealer spreads easier. 



We recommend five to six gallons to the hun- 

 dred square feet, or one square. When measur- 

 ing your boiler surface, include the top as well as 

 side walls, and make the entire setting AIR- 

 TIGHT. 



Price $1.50 per Gallon
