Catalpa colour, grain, and figure
Expect heartwood color can range from a neutral grayish tan to a richer golden brown: nearly the entire trunk is composed of heartwood. Narrow sapwood is a pale gray.
In practical selection, the grain and texture are best treated this way: grain is straight, with an open, coarse texture.
Working notes
In the shop, generally easy to work with hand and machine tools, though care must be taken during sanding to avoid creating indents and ridges where the lighter latewood areas tend to sand more readily than the earlywood portions. (Using a rigid-backed sanding block is recommended.) Turns, glues, and finishes well, though pore-filling is necessary to obtain a smooth finished surface.
Although severe reactions are quite uncommon, some species of Catalpa have been reported to cause skin irritation.
Catalpa should be sold by project fit: colour, workability, durability, and the format the customer actually needs.

Use caution
Avoid specifying it by name alone; confirm board size, moisture, colour, figure, and the project environment before buying.
Finish strategy
Test finishes on offcuts first, especially when colour, blotching, outdoor exposure, or grain filling matters.
Buying note
Choose boards, slabs, plywood, blanks, or posts based on the project rather than species name alone.
