LP Smart Siding is a composite siding material, made to work like -- and resemble -- traditional wood paneling. The installation process is the same as with any other wood paneling, with the panels held securely in place by a series of siding nails. Painting LP Smart Siding is slightly different that traditional wood paneling, though. All Smart Siding panels come pre-primed, ready for finishing immediately after installation with a layer of your favorite exterior topcoat paint.

Step 1

Mask off the sections of the siding or trim you wish to leave unpainted, or to leave for another paint color. Place a tarp over any windows or doors and tape them securely in place.

Step 2

Thin the exterior acrylic with paint thinner. Check with the paint manufacturer to determine the ratio of paint to thinner needed for your particular brand of HVLP sprayer. This will give you the misting consistency that the sprayer needs for efficient application. Fill the paint reservoir on your HVLP with the correctly thinned paint, then set the reservoir onto the sprayer to ready the sprayer for use.

Step 3

Stand with the end of the sprayer 8 inches from the LP Smart Siding surface at a corner area. Make sure you have the sprayer pointed directly at the siding surface, at the lowest plank, and not at an angle, as angled spray will produce uneven edging, leading to lap marks. Press the sprayer's trigger to start the paint mist and direct the mist over a single plank. Cover a 10-foot long section of the siding plank with the spray, using a back and forth motion to keep the spray straight. After covering the first 10 feet, move to the next higher plank and repeat the process. Grab a helper to hold a ladder if you need assistance to reach the higher siding panels.

Step 4

Stop spraying and switch to a paint roller. Back-roll the paint into the Smart Siding by moving the roller in the opposite direction in which you sprayed the paint. This should help the paint penetrate and smooth out any spraying inconsistencies. Move on to the next 10 feet of siding and continue the process, repeating until finished. Wait two hours to allow the paint to begin to dry.

Step 5

Apply a second coat of paint to the entire surface. Use a light layer to cover any areas missed by the first application. Don't back-roll this second coat. Allow 24 hours of drying time.

Step 6

Strip off the masking tape and tarps. Paint any trim pieces with a paintbrush, then wait 24 hours for the trim paint to dry to complete the siding coverage.
