Flexible paint for walls and ceilings

A wall or ceiling panel comprising a plurality of planar gypsum wallboard panels disposed adjacent to each other, each panel secured to support structure on rear surfaces thereof and having front surfaces aligned in a common plane without a joint filling composition between said wallboard panels, wherein a joint between said plurality of panels is coated with a continuous flexible latex coating composition having a viscosity of about 55,000 to 70,000 cps. so that flexing of said adjacent panels does not crack said coating composition after said coating composition has dried, said coating composition comprising:

• Wet Latex Coating
• Composition Component
• Wt. %
• water
• 10-50
• humectant
• 1-10
• surfactant
• 0.01-1.0
• dispersant
• 0.05-1.0
• acrylic polymer or copolymer having
• about 16-25
• a particle size in the range of about
