When Christian and I returned this is what we saw.
Mark bent over staining in between the cracks.
Christian, of course, wanted nothing more than to help daddy.
Since it's stain and not just for fun that wasn't an option.
But I did get him the same container and same foam brush.
I put the same amount of sealer (water) and told him his job was to seal the driveway.
He totally bought it!
This lasted about 45 minutes.
He is so cute when he copies his daddy!
