PART 2 Exterior Painting and Restoration

Published on

"Exterior Painting Restoration" is the phrase I coined to describe the Attitude and Procedures required to produce long lasting exterior paint jobs on older buildings. Treat the CAUSES of paint failure and not just the SYMPTOMS. Create long lasting, beautiful paint jobs. Most painters only deal with the Symptoms, and therefore the jobs fail prematurely. This PowerPoint Presentation Includes sections on identifying the problem areas, how to effectively treat them, paint stripping, wood and plaster repairs, use of epoxy fillers and consolidants, issues regarding old lead paint, and more. Learn the tricks and tips of exterior painting and old home restoration from a specialist.

PART 2 Exterior Painting and Restoration

  1. 1. PART TWO
  2. 2. EXTERIOR PAINTING RESTORATIONPART TWOThis being a continuation of what was begun in PART ONE.If you are interested in a more detailed explanation of the products,techniques, and procedures shown in these presentations, you may wishto also view the complementary (and complimentary) “White Paper” (aka“Abstract”) entitled (take a wild guess) “Exterior Painting Restoration”. It isavailable at :www.slideshare.net/rdufort/exterior-painting-restoration-how-to-articleFinally, for those of you who like to see even more photos, you arewelcome to visit our Flickr photo heaven, particularly the photo set entitled(take a guess) : www.flickr.com/photos/magicbrushinc/sets/72157626367625417/
  3. 3. A Tale to Tell – every picture tells a story. You just have to read it.

  8. 8. A Word to the Wise: Bondo Bad(It’s inflexible and designed for metal, not wood….)
  9. 9. We refer to this as “dry-rot”
  10. 10. We refer to this as “dry-rot” Usually is not fungi related – we use the term “generically”. Generally non-structural (if structural, probably is fungi related). Prevalent around old rusted nails and heavily exposed, weathered surfaces. (Windows sills, for example.) Deteriorated Putty/Patches often “signal” the presence of decay. Punky, decayed Wood incapable of being successfully patched “as is”. How do you treat this condition?
  11. 11. “Dry-Rot”Treatments
  12. 12. “Dry-Rot” Treatment Phase One• Prepare Surface – remove deteriorated paint.• Remove rusted nails, as possible, and resecure.• Dig out loose, “punky” wood. What comes out easily with a scraper is usually sufficient.
  13. 13. “Dry-Rot” Treatment Phase Two• Drill 1/4” holes around all effected areas (but don’t drill completely through the piece of wood).• Inject Epoxy Consolidant with Turkey Baster (or approved equivalent- e.g. plastic mustard and ketchup bottles).• Saturate and Repeat.
  14. 14. “Dry-Rot” Treatment Phase Two• Drill 1/4” holes around all effected areas (but don’t drill completely through the piece of wood).• Inject Epoxy Consolidant with Turkey Baster (or approved equivalent- e.g. plastic mustard and ketchup bottles).• Saturate and Repeat. What’s an Epoxy Consolidant?
  15. 15. Consolidants have many uses
  16. 16. Consolidants have many uses Wood, of course:Two component Epoxy Consolidants areabsorbed through the endgrain of wood,saturating the looser deteriorated woodand then “consolidating” those fibersinto the surrounding sound wood. Onlythen is it possible to effect meaningfulrepairs.
  17. 17. Consolidants have many uses Plaster as well: Epoxy Consolidants infiltrate the loose plaster, often deteriorated due to water damage, and solidify into a solid, repairable, surface. Many plaster elements can be successfully salvaged using these techniques.
  18. 18. Consolidants have many uses Even Gutters: The gutters on many older California buildings are made from redwood, and are usually poorly sealed (if at all). Once cleaned, they can be treated with the epoxy consolidants and then painted. Thus maintained, they will continue to last a very long time.
  19. 19. Consolidants have many usesIn addition to being used to consolidate repair areas, thelower viscosity (watery) consolidants can be used as theinitial sealer coat for all stripped wood. Some are highlyviscous (thick) and are not as suitable for this use. Theconsolidant is absorbed into the wood (with virtually nofilm build) and insures the successful adhesion of paintprimers that follow. (FYI - We highly recommend usingacrylics for primer and finish coats.)We also use the consolidant to seal our epoxy fillersprior to priming. (In fact, it is excellent for sealing mostpatching materials. Highly recommended.)
  20. 20. “Dry-Rot” Treatment Phase Three• After consolidating, patch voids with an Epoxy Filler designed to be used with wood. Sand smooth after curing.• The final step is to seal the filler with another coat of the consolidant.• NOTE: many fillers are not designed for exterior wood application – generally, they are too “hard” and do not retain the flexibility to move with the substrate as it expands and contracts with the weather.
  21. 21. Fun with Epoxy!ISSUES:- Restore vs. Replace- Permanent?- Compare Epoxy to Other Fillers
  22. 22. Repair, Rebuild, Restore, Reward • Wood must have some structural integrity (Totally rotted pieces should be replaced.) • Epoxy filler is applied with putty knife or whatever tool works best for the given situation. Generally avoid “skimming out” in very thin layers. • Can use lacquer thinner to “smooth” surface prior to curing. (Will still require sanding in most cases.) • “Chopsticks” are good for pushing filler into drill holes. Really.
  23. 23. Interesting Epoxy Filler Facts• Working Life of about 30 minutes.• Mix 1:1 (most epoxy fillers).• Thorough mixing (kneading) necessary.• Can be sanded, shaped and drilled. This allows one to re-create profiles of damaged moldings and ornamental elements that would otherwise be expensive to replicate.• Curing generates heat which in turn accelerates curing. Since larger masses generate more heat than smaller, it follows that large patches will cure faster than small patches!
  24. 24. More Interesting Epoxy Facts• Superb bonding to consolidated wood.• Seal with Consolidant prior to Priming.• Not Recommended in Seams and Joints unless part of a large void.• Larger Holes can be Partly Filled with Wood (less expensive, too).• Near Permanent Repair.• Other Fillers are “No Comparison” – we have inspected epoxy patches that are over 20 years old and are still holding up wonderfully. (Save the bondo for your trucks, please...)
  25. 25. More Interesting Facts To Come…Now that the basics ofEpoxy Consolidating andFilling have beenmastered covered, itwould seem that one isfinally ready to undertakethe “painting” portion ofa “Painting Restoration”.Sorry, not so fast. Thereare a couple morecomponents yet to beassimilated. Please continue on to PART THREE…
