Handyman, does Sonaborn allow the concrete to expand with the temperature?

After reading the spec sheets on both the Sonaborn NP1 and the Sonaborn SL1 both allow the concrete to expand/contract, but the SL1 is a self leveling product. Handyman since he has vast experience with this product beyond just reading the spec sheets he might explain it better, but here are both....

Looks like both are quality products. Note that because the SL1 is self leveling, for very deep cracking a foam backer may be needed. This is why they make both the NP1 and the SL1
Hope this helps...
