A good rule of thumb is 50 degrees and above. Some paints are rated to be applied at much cooler temperatures but I do not recommend painting below the 50 degree mark.
Todays waterbourne acrylic paints and stains are very fast drying under proper temperatures and humidity. Once dry, these products will withstand light rain without and damaging effects.
Yes. Although most stains and paints on the market today are labeled "paint and primer in one", it is still necessary to prime all bare wood areas with a quality primer. Oil primer is usually the best option as it seals open wood much better than acrylic primers.
You will most likely not see much of a temperature difference inside your home with a darker color paint on the exterior. However, keep in mind that the darker the paint, the more prone the paint will be to fade on the sides of the house that have the most sun exposure.
Peeling paint can be caused for a variety of reasons. If a substrate is not dry before applying paint it will bubble and or peel prematurely. A dirty surface prior to painting can also cause bubbling or peeling. Failure to properly scrape old coatings will cause new coatings to peel. Prolonged periods of sun exposure will cause paint to peel.
No. Although this may look neat and clean, caulking the undersides of all of the siding will not allow the house to "breath" which may cause premature peeling.
Yes. Be sure to use a wider fan spray tip and stay far enough away from the siding with the spray as to not damage the siding. Also, be sure not to force water up under the siding boards themselves. Spray straight on or even slightly angled downward to prevent this.
Yes. Just like with power washing siding, you will want to use a larger fan spray tip and keep a safe distance from the deck boards to prevent any damage or "spray stripes" in the wood. Once the decking dries, it will leave the wood fibers raised that will give the deck a "furry" look. Be prepared to lightly sand the wood to smooth it back down prior to staining.
In my opinion unless it is aluminum siding, a hand brushed paint job is superior to a sprayed house and will result in a better finished product. A brush is able to get into tight spaces a sprayer can easily miss. Overspray is also another concern on anything that is left uncovered or not taped off such as windows, roofing, driveways, walkways, plants, trees, decking etc.
Typically after 24 hours it will be safe to rehang items.
Interior paint just like exterior paint fades just not nearly as much. Interior walls get dirty and stained by normal household activity. Typically you only have a week or 2 to do touchups after painting to ensure an even match with the rest of the wall.
No. All white ceiling paint has a bit of a different hue. It is not advisable to touch up spots on a ceiling if you are looking for a uniform look.
Yes. Costly paints both interior and exterior will almost always cover over existing coatings better, will be more durable, and will have better color retention.
