How To Paint Sharp Lines on Textured and Uneven Surfaces

Painting sharp lines on textured or uneven surfaces can be frustrating. Here are some tips to get the job done right.

Painting equipment laid out on a drop cloth. Paint tray, Paint Can, FrogTape Multi-Surface Painter's Tape, Sponge, Paint Roller, and Paint Brush

Supplies Needed

  1. FrogTape® Multi-Surface Painter’s Tape
  2. Clear latex caulking with caulk gun


  1. Apply FrogTape® to wall in the desired area, making sure the tape is straight and level. Press down firmly to seal.
  2. With a caulk gun loaded with clear latex caulking, carefully apply a thin line of caulking along the edge of the tape, then wipe away excess with your thumb or finger. The moisture of the caulking activates FrogTape’s PaintBlock® Technology, which causes the edges of the tape to swell to create an additional seal against paint seepage. Clean excess caulking from your hands with a wet towel or sponge.
  3. Important: Painting and tape removal must be completed before the caulking dries. If the caulking is allowed to dry, paint may pull away when you remove the tape.
  4. Using a brush, paint along and over the tape and caulking. Be sure to completely cover the area with paint.
  5. While the paint is damp and before the caulking is able to dry, remove the tape.

Note: Some caulking might bleed under the tape, but since it’s clear, it won’t affect the end result.
