Loctite PL Premium construction adhesive: cure time

Loctite PL Premium is a construction adhesive. The manufacturer lists several times on its technical data sheet.

The sheet lists open time, repositioning time, clamping time and cure time separately. It also says the times depend on temperature, humidity, porosity of the surface and the amount of adhesive used.

The Henkel technical data sheet gives a cure time of 24 to 48 hours at 78°F (25°C) and 50% relative humidity. It says cure time is significantly increased in cold temperatures or low humidity.

Limits of this figure

The same sheet says to use mechanical support for 24 hours while the adhesive cures.
