In order to prevent contamination, wet paint samples should be taken from a
newly opened container. Paint should be stirred to ensure even consistency
before sampling and all equipment used should be cleaned prior to use. Liquid
paint samples should be stored in appropriate sealed packaging which will not
react with or contaminate the sample. In the case of multi-component coatings
(where on-site mixing of several components is required prior to application),
samples of each component should be taken and the required mixing ratio
recorded. When a sample of wet paint is taken from a container, details of the
paint should be recorded, e.g. details required for the IAFS Certificate along
with a batch number for the product.
