Show FIRST AID rrM 1 fay Roger C. Whitman as a "vapor barrier" and protect the insulation from any penetration penetra-tion of moisture from the house air, rising through the ceiling plaster. plas-ter. Get what is called vapor-proof vapor-proof paper, for not all waterproof water-proof papers are vapor-proof. Your dealer in insulating materials ma-terials will have it in stock. After putting in your insulation, cover the material with tar paper or other strong paper to protect it from dust. (Insulating batts and blankets come with a vapor-proof covering.) Or you can lay flooring instead. BADLY WORN LAUNDRY TUBS Question: The smooth finish-assumed finish-assumed to be cement has worn off the bottoms and a short distance dis-tance up the walls of our laundry tubs (twin). They have been in use since 1940. Now the coarser material, ma-terial, fine gravel, is exposed, and from time to time small particles are found adhering to the wash. I shall appreciate your giving me any suggestion which may be translated into a method of repairing re-pairing this damage. Answer: If not too rough, you might be able to smooth the surfaces sur-faces by rubbing with a coarse abrasive stone. If this fails, you might call in a competent concrete con-crete worker. He may be able to clean the surfaces with a muriatic muria-tic acid solution, rinse with water and put in a layer of cement mortar. mor-tar. If he does not think this idea practical, you could have a sheet metal (tinsmith) worker cut a sheet of stainless steel to fit the bottom of the tubs. The sheet should be taken out after each washing for thorough rinsing with clear water and the tubs should be allowed to dry out. Of course, the better plan would be to have good modern porcelain tubs put in, and get rid of the old ones. INSULATION IN ATTIC FLOOR Question: Please advise whether wheth-er it would be of any value to place waterproof paper between the joists in the attic (I.e., the ceilings of the rooms below) before be-fore pouring or blowing in the Insulation In-sulation material. 1 intended to do the work myself and would appreciate ap-preciate your advice, since it will require considerable additional work to lay the paper, and unless it will make the insulation more effective. I do not wish to go to this extra expense. If you do consider con-sider this waterproof paper an advantage, ad-vantage, would you tell me what type to use? Answer: Your plan Is entirely correct, for the paper would act |
