Light Block Kit

Keep light inside a structure, where it belongs! Seal all light leaks easily by pressing Ribbon Putty into interior corners and joints. Affix it along the bottom edges of structures to secure building to layout surface and block light from bleeding along foundations. Apply Masking Paint to keep light from glowing through walls and shining through windows. Putty will cover 96 linear inches (243 cm) and Paint will cover 1,200 sq. in (77.4 sq dm).
