Surface Preparation and Painting of Hollow Metal Doors by House of Doors - Roanoke, vA
HOUSE OF DOORS, INC RECOMMENDED GUIDELINES FOR PREPARATION AND PAINTING OF HOLLOW
METAL DOORS AND FRAMES:
MAINTENANCE
OF HOLLOW METAL DOORS AND FRAMES SHOULD BE DONE IN ACCORDANCE WITH SDI 124-98
“MAINTENANCE OF STANDARD STEEL DOORS AND FRAMES”
PRIMING AND
PAINTING OF HOLLOW METAL DOORS AND FRAMES SHOULD BE DONE IN ACCORDANCE WITH SDI
A250.8, SECTIONS 2.1.3, 2.1.4 AND 2.1.5. WE ALSO RECOMMEND FOLLOWING ANSI A250
RECOMMENDATIONS, INCLUDING BUT NOT LIMITED TO A250.8.4.1-4.6 AND APPENDIX “B”
LISTED BELOW
A250.8-2003 “RECOMMENDED
SPECIFICATIONS FOR STANDARD STEEL DOORS AND FRAMES”:
APPENDIX B,
GENERAL CONSIDERATIONS, AESTHETICS
“THE
PRODUCTION OF STEEL DOORS AND FRAMES RELIES ON A VARIETY OF MANUFACTURING
PROCESSES INCLUDING SPOT WELDING, PROJECTION WELDING, ARC WELDING GROUND
SMOOTH, GRINDING FILLING ETC. THESE PROCESES MAY RESULT IN A SHOW-THROUGH AFTER
APPLICATION OF FINISHED PAINT. THESE CHARACTERISTICS ARE INHERENT IN PRODUCTION
AND ARE NOT TO BE CONSIDERED AS MANUFACTURING DEFECTS.
THE
SHOW-THROUGH CHARACTERISTICS INCREASE AS THE PAINT GLASS
INCREASES. THIS STANDARD RECOMMENDS A MAXIMUM PAINT GLOSS OF 20% REFLECTANCE,
MEASURED USING A 60* GLOSS METER, WHICH SHOULD BE SUITABLE FOR MOST
APPLICATIONS. TRANSLUCENT PAINTS MAY EMPHASIZE SHOW-THROUGH CHARACTERISTICS AND
THEIR USE IS NOT RECOMMENDED.”
HOUSE OF DOORS, INC DOES NOT RECOMMEND THE USE OF GLOSS
PAINTS. SPRAYED ON GLOSS PAINTS ARE PARTICULARLY DIFFICULT TO USE. IF GLOSS
PAINTS ARE USED, A CONSIDERABLE AMOUNT OF CLEANING, SANDING AND PAINTING WILL
BE REQUIRED AND MAY STILL EMPHASIZE SHOW-THROUGH CHARACTERISTICS.
HOUSE OF DOORS, INC DOES NOT RECOMMEND USING BLACK OR
DARK COLORED PAINT ON EXTERIOR DOORS.
HOUSE OF DOORS, INC DOES NOT RECOMMEND THE USE OF WATER
BASED PAINTS AS FINAL TOP COATS. IF WATER BASED PAINTS ARE USED AS A FINISH
COAT, YOU SHOULD FIRST PRIME THE DOOR AND/OR FRAME WITH A PRIMER WITH RUST
INHIBITORS RECOMMENDED BY THE PAINT MANUFACTURER FOR BARE STEEL. IF THE DOOR IS
NOT PRIMED IN THIS WAY, ALL SCRATCHES AND NICKS THAT EXPOSE BARE METAL WILL
DEVELOP RUST. IT IS ALSO EXTREMELY IMPORTANT TO CLEAN ANY AND ALL METAL
PARTICLES THAT MAY BE ON THE PRIME COAT PRIOR TO FINISH PAINTING. THESE MAY
INCLUDE SMALL METAL SHAVINGS FROM SANDING OR OTHER JOBSITE OPERATIONS AND WILL
CLING TO THE DOOR AND/OR FRAME WITH STATIC ELECTRICITY. THESE PARTICLES WILL
SHOW RUST THROUGH THE FINISH PAINT BUT ARE NOT RUST OF THE ACTUAL DOOR AND/OR
FRAME.
FAILURE TO FOLLOW THE ABOVE
GUIDELINES/RECOMMENDATIONS VOIDS ANY AND ALL WARRANTY EXPRESSED AND/OR
OTHERWISE
