Hp12 or weber lac

[BigK]

Hi lads, going over a small rendered wall that's cracked, have to top it off with white s&c, was going to base coat it with one of the above & mesh.
Which one would be best? Or are they essentially the same product??
Cheers

Anyone? Same gear?

I Would go hp12 pal instead of lac is designed for low load ie thin coat you stand more chance with hp12
