Here in Buffalo I have ceder siding which is in good shape. I accidentally used Valspar flat latex on the outside of my house and was wondering what my options are.

Valspar says put another coat of Valspar DuraMax exterior on it - the sooner the better. Wait no longer than a month.

A professional painter says don't panic it's an ok primer and just follow up with a good latex exterior.

Some on the web say scrape and prime, others say just prime again and paint, others say "paint is paint" just go over again with exterior.

Any comments?
Nestor, what do you think

you could but i do not reccomend it. as a painting contractor , i can tell you it would flake off very quickly,and wouldnt be worth the the effort. the only thing you could do if you were adamant about doing ti would be to oil prime the door with a good primer like X-I-M then top coat it with your interior paint.

Leonard,
Why prime over the interior? How does this improve the situation if the interior coat loses adhesion? Also, why then top coat with the interior? Would you not want to use an exterior?

You need to clean your exterior home properly before you do any coatings. Make sure you do this. You do not need to use high PSI to achieve a clean home free of mold, algae, dirt and pollutants. use 16ounces of Simple Cherry, 3.5 Gallons of 12.5% SH and fill the rest of the 5 with water. Only use the black tip for applying chems to apply and rinse your home.

This will clean your windows and leave them streak free as well as remove any green and black on your home. It will be paint prep ready to prime and finish.

As a Allentown Paint Contractor, we would use a bonding primer followed by an entire caulking of the house. We would allow it to dry in for a day and then coat it with a 100% acrylic latex coating from Sherwin Williams or Benny Moore.

This is a generic answer, but I do not know all the details.
