According to HUD standards, how many square inches should paint chip samples be?

According to HUD standards, paint chip samples should be a minimum of 4 square inches. This size is important for ensuring that the samples collected are representative of the painted surface and can provide adequate material for analysis. A sample that is too small might not capture enough of the paint's properties or may not adequately represent the condition of the painted surface, leading to inconclusive or inaccurate test results. Ensuring that the sample is at least 4 square inches helps in meeting the requirements for reliable and effective assessment of lead hazards in the environment.
