What causes lumps in paint that has been stockpiled? Management of storage expiration.
Sites that secured an excess of paint due to supply concerns in spring 2026 should be cautious. Paint that has been stored for a long time may settle or thicken, leading to clumping and color variations.
When I used the paint that I had secured in abundance during spring, it had lumps. The color also looks slightly different from the previous batch. 【What is happening now】 In spring 2026, there were successive shipping restrictions and order suspensions for thinner and solvent-based paints. Is the paint secured at that time still sitting in the warehouse for a long time? 【First, please check here】 □ There is a hard sediment at the bottom of the can → The pigment has settled and solidified □ Even after stirring, particles remain → Some of the paint has started to solidify □ When opening the can, there is a film on the surface → The surface has solidified due to exposure to air 【Countermeasures you can take starting today】 1. Write the arrival date on the can and use them in order of age 2. Check the expiration date indicated by the manufacturer and test the paint before using any that has expired 3. Stir thoroughly before use and strain through a mesh 【Free materials】 You can download a document summarizing the scope of Eiwa Kogei's powder coating services for free from the related catalog on this page.
