How to Apply Water Based Varnis ?
To apply it effectively to a work surface, it is helpful to understand the parameters for it. You must take into account aspects such as the length of time required for each layer to be fixed, the best time span for applying between consecutive coats and taking into account the reaction to humidity and temperature.
Working with the Right Temperature
You should note that the temperatures in your environment are adequate enough to facilitate curing. In general, varnish will not cure well if applied at temperatures below 65 degrees.
The best temperature range is between 70 and 75 degrees. Applying the varnish at temperatures above these is also not advisable as the solvent in the finish tends to evaporate too quickly, leaving the varnish to set prematurely.
Preparing the Work Area and the Part to be Varnished
It is essential that the work area is free of dust, wipe the piece to be varnished with a damp cloth and let it dry.
If the application is to be carried out within the workshop facilities, other sanding tasks should definitely not be carried out simultaneously.

To apply, submerge the brush in the sealer and let the excess drain away. Proceed to brush it on the wood, along the grain, without leaving drips or puddles, you must let the piece dry overnight before sanding.
The amount of sealer layers depends on the porosity of the wood. Repeat as necessary.
