- When do I apply Open Time Extender #0090 Additive?
-
Use the Open Time Extender #0090 Additive when coating large surfaces or in circumstances where the varnish will dry faster than desired. Thing about varnishing:
- At a room or surface temperature above 25˚C.
- In a room with an RH lower than 45%.
- In a room with strong air circulation/ventilation or constant airflow over the floor.
Especially in combination, these are circumstances where the water from the varnish has completely evaporated before the varnish has been able to flow properly.
When coating large surfaces, it often takes longer to make wet-on-wet connections. By using the Open Time Extender, the varnish layers have more time to flow into each other.
- What can I do to avoid drying conditions that are too favourable?
-
It’s smart to look at varnish and drying conditions at least two days in advance. This gives time and opportunity to take measures, for example:
- Check the radiation of the heating.
- Check the floor temperature with an infrared thermometer.
- If there is underfloor heating, lower the water temperature in the system step by step to 25˚C.
- Set the room thermostat to continuous 18˚C.
- Check whether sun protection is present and whether it can be used to prevent heating by the sun.
- Prevent drafts by closing windows or doors and look at options to ensure soft ventilation. For example, by opening ventilation grilles or switching on an extractor hood.
Adjust the work schedule if necessary. Even on a very hot summer day, the room will still be nice and cool at seven in the morning.
- When does applying Open Time Extender #0090 Additive have no added value?
-
If one of the (processing) conditions is outside the specified bandwidth or due to a combination of drying conditions which are too favourable. The Open Time Extender, for example, cannot absorb (too) fast evaporation that takes place on a floor that has been heated all day by bright sunlight.
- How far in advance do I check varnish and drying conditions?
-
Checking the varnish and drying conditions should be part of the whole work process. Discuss them at the quotation stage and record the agreements in your quotation and order confirmation. During the execution. Do not wait with the check until you have to start varnishing. Then you are often too late to improve the conditions.
Start the check 48 hours before starting applying the varnish. This gives all involved parties time and opportunity to take measures.
In many cases, you will already be on location, because the wood still needs to be placed or sanded.
Consult our varnish checklist for a detailed overview.
