Tips When Adding A New Layer Of Wet ‘Tufa
Over A Dried Layer

I received an email from Regina who asked:

Can we add fresh hypertufa to an existing, partially cured layer that also has a few cracks on the top half? And should we use bonding agent? Thank you, Regina

My reply:

Hi Regina:

Yes you sure can … it is advisable to dampen the existing ‘tufa, then paint on the bonding agent and then add your fresh ‘tufa. Many crafters certainly will also add some bonding agent into the new hypertufa. Just make sure to adjust your liquid ratio accordingly.

And please know that the cracks you are getting aren’t a “bad” thing … in projects like large spheres, you will almost invariably get cracks. And that’s OK. That is why most people figure on doing at least 2 layers.

Hope this helps. Sounds like you are having some success now  Keep me posted.
