  1. That’s fine. Why not use Loxon XP? 2 coats, backroll the first coat then spray the second. It’ll skick just fine to the brick.
  2. Never used the Ultra Spec outside.  Recommend only use top-of-the-line paints when possible.  For BM, Regal Exterior is a good choice.
  3. The Loxon XP is an elastomeric coating. Benjamin Moore also has an elastomeric coating, works good BTY.
  4. Yes, better than most satin acrylics.
  5. Mor-Flexx by Sashco is really good, it’s a sanded caulking type of filler.
  6. Might try a mold additive for the top coat. A  mold resistant primer doesn’t do any good for the top coat.
  7. Everything can peel.  Make sure to do the correct prep and fix any roof or gutter leaks.
  8. Your welcome!!

Consider FIRST wash it all down, but only by hand not by pressure… then inspect for cracks and holes, and fill with exterior grade spackling and or putty… then prime with a high quality masonry primer (use Sherwin Williams brand) finally top coat with Sherwin Williams A-100 Latex  and use a FLAT finish if possible (looks better on old brick houses…) Good Luck!

Am concerned about power washing- as mortar is sandy and dont want it blown out- we were going to power wash the window sills for sure- 

  1. how to ‘hand wash’ the brick- the brick is rough type- what would be used. Painter talked about a gentle power wash but dont know. want brick cleaned- imaging hours and hours if it has to be hand washed and his price going way up
  2.  difference between loxon and loxon xp? are these both elastomeric?
  3. was looking to use a good masonry primer one coat and 2 regal or duration coats. Are you saying I can just  do 2 coats with loxon or loxon xp? its expensive
  4. Thanks!

I answered your question about what to do and what brands to use, 2 coats is all you need, primer and top coat… as for washing, I would NOT advise ANY power washing anywhere at all… simply use the garden hose water along with a scrub brush attached to a 4ft extension stick (available at most paint stores or Home Depot) and scrub gloves or heavy cloth rags and a large bucket of water with TSP (tri sodium phosphate) added… Good Luck!

  1. A gentle powerwash is low pressure (1000psi or less) and 2 feet from the surface, mild soap (house wash) can be injected for trouble spots.  A stiff push broom can be used as a scrub brush if needed.  Rinse well to remove the soap.
  2. Regular Loxon is a thick paint, non elastomeric, while the Loxon XP is a masonry coating (true elstomeric).
  3. A prime coat and then 2 coats of paint is fine. The Loxon line is for contractors who need to speed things up and still get a good result.  The Loxon XP doesn’t need a primer on brick or stucco, 1st coat thick and backrolled then a spray only 2nd coat.  Less labor=more profit.  Worth the extra expense for the materials to a contractor.
