I have been using your products for years and I'm very happy with them.
My question is can this stain be sprayed on using a Wagner Power sprayer?
Also, can this product be tinted to match an existing finish?
Thanks,

Steven,
Ultimately, WeatherSeal should be brushed onto the surface. Spraying is
just a means of transferring WeatherSeal from the container to the surface
of the log. The mistakes I have seen when spraying WeatherSeal is that the
spray applied WeatherSeal never is truly brushed or too much WeatherSeal
is spray applied onto the surface and the excess amount cannot be adequately
brushed out. Because of WeatherSeal's high viscosity, a heavy-duty contractor
sprayer is recommended. The smaller units generally do not have enough power
to atomize the WeatherSeal so it can be applied uniformly.

I built a log home with Wisconsin Log Homes last year. I put 1 coat of Weatherall
Rustic Pine on late last summer. I'm going to put on a 2nd coat this spring
/ summer. Do you have any recommendations on what type of airless sprayer
best works with your product? I have read your guide for application, but
am inquiring what additional info you can supply to get the best effectiveness
from your product. I do not want to thin product. I am trying to maximize
protection, while still applying with easier methods. I do have your installation
guide, but your only statement says it can be applied with a sprayer. Please
furnish me with as much info as possible. If there is any additional info
I can give you, I will. I will be looking forward to your reply.
Thank You,

Don,
You will require a spray unit that has enough power to atomize the WeatherSeal
properly and handle the higher viscosity of WeatherSeal. Wagner Spray Tech,
the manufacturer of Wagner Spray Guns, tested WeatherSeal when we first
introduced it in the early 90's. They reported that their 100-watt homeowner
units worked well. The larger contractor series Wagner spray units will
perform even better than the homeowner unit. Binks and Graco also make professional
airless units. If you plan on spraying WeatherSeal make sure it is thoroughly
mixed before spraying. Use a mixing blade for hand drills to mix WeatherSeal.
Care must be taken to not over apply WeatherSeal on the wood surface. Remember
that WeatherSeal requires immediate brushing once you spray deposit it on
the log surface. If you deposit too much WeatherSeal onto the surface, there
will be an excess of WeatherSeal to spread without enough surface area to
spread it over. You need to gauge the amount you spray onto the surface.
It's a matter of experience. Start slow and get a "feel" for the proper
application technique. Also, because you already have a single coat of WeatherSeal
on the wood surface, a light wash with trisodium phosphate (1 cup/gal) is
a good idea. The wash will clean and prep the surface and insure a good
bond of the topcoat to the previous coat. Make sure to thoroughly rinse
the TSP residue off the cleaned surface before proceeding to topcoat with
WeatherSeal. If not rinsed clean with fresh water, the soapy residue could
interfere with the WeatherSeal properly bonding to the surface.

Is WeatherSeal sprayable? It only refers to brush application due to its
thickness.

Dear Dick,
WeatherSeal can be airless spray applied IF it is immediately brushed after
spraying. If sprayed without brushing, too much material may be deposited
on the wood surface, lap marks and streaks are practically unavoidable,
and overall appearance will suffer. Additionally, other coating problems
can result due spraying too thick of a coating onto the surface without
brushing. I have seen blisters and peeling as results of spray applying
too thick a layer of stain. Brushing allows the applicator to better control
the amount deposited on the surface. If the applicator decides to spray
and back brush, they may dilute WeatherSeal with mineral spirits up to 16
ounces per gallon of stain. Dilution with mineral spirits will help to better
atomize WeatherSeal in certain sprayers and it will help wet the WeatherSeal
onto the surface. Spraying partially evaporates the solvents in the stain
particles as they are traveling through the air. The mineral spirits adds
additional solvent and helps keep it wet and easier to spread when brushing.
Use a contractor series Wagner or Graco airless sprayer. Tip size to use
is between .015-. 017.
