How to Apply TWP Stain with Pump SprayerAre you looking for a quicker, easier way to stain your exterior wood TWP Wood and Deck Stain? A low-pressure pump sprayer can be a good choice but you will need to be careful with overspray and an even application.

Using these tips below will help to ensure your TWP Stain is applied evenly, with a faster application time.

Note: These spraying tips can also apply to using an airless sprayer. Always use quality pump sprayers. Fan tips are best. Keep sprayer fully pressurized throughout the application for an even flow. We offer the Chapin Pump Sprayers.


  1. Mix your TWP Stain thoroughly with a mixing stick or drill mixer.
  2. When applying to verticals such railings or a fence, use a large poly tarp to protect concrete, grass, and shrubs.
  3. Apply the TWP stain using the pump sprayer to the vertical areas. Walk around and repeat the process on the other side. Be careful to make sure all overspray lands on the tarp only. Do the verticals in small sections of about 8-10 linear feet at a time.
  4. When done with the 1st section, immediately back wipe any drips using a stain pad or brush. Scan the section for missed spots. At this, time, apply a second coat to the top of the railing if needed. Check flooring under the railings for any puddles of stain and remove excess stain.
  5. Repeat this process, going around the railings until you reach the opposite side. Re-check for drips and missed spots.
  6. Flooring is next. Using a stain pad or brush, edge out flooring that is next to the house. Applied at least 2 feet away from the house.
  7. Use the pump sprayer to lightly cover the remainder of the flooring.
  8. Apply a second coat to entire flooring using stain pads or brushes within 20-40 minutes of the first coat. You can walk on your first coat while wet but be careful to not step in your second coat. Only apply as much TWP stain that wood can handle, as overapplying can result in premature stain failure on the horizontal surfaces.
  9. Finish deck steps using same methods as above.

It is important that you properly dispose of all oily rags. Saturate oily rags, cloth tarps, etc. with water and lay flat to dry outside. Never store oily rags near or inside a home/garage while wet with oil!

We hope this gives you a head start on how to use TWP to stain your deck with a sprayer. If you have any questions, thoughts, or suggestions, we want to hear them!

    I'm not clear whether you actually recommend walking on first (sprayed) coat? That would be wet on wet of course. It seems one would have to wear some kind of painter's booties

    Any reason I can't apply second coat with sprayer?

      If you spray, use it for the first coat. Apply the second coat wet on wet with a stain pad or brush to ensure it applies evenly.

      Use mineral spirits to clean the sprayer.

    Do you need to thin the stain in a sprayer? Will a garden sprayer work?

      You cannot thin the TWP and yes, it will spray with a quality pump sprayer.

    I plan to use the Graco X5 airless sprayer to apply the 1500 series. Are there any caveats with thismethod?

      How do you clean an airless sprayer after using twp? Water from a garden house or do you need paint thinner or something similar?

      No issues. Just follow the guidelines above on applying and wiping any drips. Be careful of overspray on windy days. It can travel far.
