12. Surface preparation
All concrete to be treated must be
clean and have an ”open” capillary
system.
Remove laitance, dirt, grease, etc. by
suitable means.
20. Three elements of a
successful
Vandex application
1. Surface preparation
2. Product application
21. Application of Vandex products
Prewatering
Surfaces must be carefully prewatered
prior to the Vandex application.
The concrete surface must be damp
but not wet.
23. Do not apply the products at temperatures
below the values indicated on the product
data sheet or on frozen substrates
24. Do not apply the products at temperatures
below the values indicated on the product
data sheet or on frozen substrates
Control of material consumption in
relation to the surface => correct layer
thickness
25. Do not apply the products at temperatures
below the values indicated on the product
data sheet or on frozen substrates
Control of material consumption in
relation to the surface => correct layer
thickness
When problems arise, stop the application
and investigate => damage limitation
26. Do not apply the products at temperatures

Record batch number of applied material
27. Mixing
Place in a clean container and stir for at least 3
minutes with a mechanical mixer.
28. Mixing
Place in a clean container and stir for at least 3
minutes with a mechanical mixer.
The mixing times have to be respected
precisely !
29. Mixing
Place in a clean container and stir for at least 3
minutes with a mechanical mixer.
The mixing times have to be respected
precisely !
The amount of water may – depending on
environmental conditions and batch variations –
differ slightly from the specified quantity.
30. Mixing
Place in a clean container and stir for at least 3
minutes with a mechanical mixer.
The mixing times have to be respected
precisely !
The amount of water may – depending on
environmental conditions and batch variations –
differ slightly from the specified quantity.
If the mix stiffens, re-mix, do NOT add more
water!
