The Essential Differences and Functions
Materials
- Each material requires a protective layer for different reasons. The primer you choose can also depend on the situation and whether the material has had any previous painting; which we cover further below. First, though, here are the most common materials that require a coat of primerbefore painting.
Types of Primers and When to Use Them
- In some circumstances, it is not about the material but the overall situation that determines the use and type of primer you will need. Oil paint, latex, deep color pigments, and various types of stains are just a few of the situations where a particular type of primer will be needed. The three most common types are oil, latex, and shellac-based primers.
Other Considerations
