Clean ext. wall before painting?
I'm about to re-paint a garage with same color --BM Navajo white.
It's kinda messed up, with bald patches where I had adhered those little round discs that held vines. Question: Should I hose it down with Spic 'n Span (and thorough rinse) before painting? Or superfluous? TIA |

I'd do it a couple of days before painting to let it dry well. |

TIA Read any paint can, they require you to have a clean surface, paint wont adhere long on dirt and mold plus any warranty will not exist. |

Let dry well. * Sand the spots where the discs were so they don't show through the new paint. * Caulk where needed. * I would use TSP (trisodium phosphate) instead of Spic 'n Span. SnS might not wash off completely. -- Steve Bell New Life Home Improvement Arlington, TX |

PITA to jam plastic back behind the plants, but gotta do it. Question: Between the two suggestions for cleaning: 1. Spic 'n Span + bleach, then rinse or 2. TSP , then rinse (I understood TSP needed very thorough rinsing as well. T/F?) Which would be LESS damaging to the poor lil' plants? There is bound to be runoff; plastic won't protect entirely. TIA |

TIA I don't think it matters what detergent you use, just get the chalked paint and dirt off. Bleach helps kill mildew so's new paint doesn't peel. For plants, tie them up with some old pantyhose - cheap, disposable, don't damage the plants. Cover plants with plastic during washing, if you are worried. Plastic tarp will do fine, but don't leave on with hot sun shining, cause that can burn the plants. In my experience, bleach won't hurt plants as long as they are rinsed. |

Question: Should I hose it down with Spic 'n Span (and thorough rinse) before painting? Or superfluous? It definitely helps to scrub it down with detergent and a strong bleach solution. The bleach will actually soften the old paint, and thereby make the new layer of paint adhere better. - Logic316 "A democracy is when three wolves and one sheep vote on what to have for dinner." |
