| Résumé : |
Whoa! Hold on ! How much thinner do you plan to add ? What thinner do you plan to add ? The data sheet says you can add up to 10% by volume.
Even so, it is not uncommon to see painters (or painters' helpers) estimating thinner addition. It takes an experienced applicator who can save precious time by estimating thinner additions. After all, the reducer is going to evaporate from the applied coating film anyway. Should it matter that the solvent is supplied by "Universal Solvent," and the coating is supplied by "Not-So-Universal Resin ?" Of course it matters, just as it matters when adding 15% thinner when 5% will produce the desired viscosity. When was the last time you actually saw a bridge painter measure viscosity ? And who actually mixes the paint? The per-son with twenty years of experience or the person who has had one year of training twenty times ? |
