JESMONITE Penetrating Sealer (For AC630, AC730, and AC830)
- Penetrating Sealer is designed for use with all Jesmonite AC630, AC730 and AC830.
- The material provides invisible protection against water and oil and provides stain resistance against many liquids and environmental contaminants.
- We recommend its use where stain resistance is a priority.
We recommend applying two coats, the second coat is applied once the first coat is tacky. This sealer should be applied with a high-quality brush spread evenly across the material surface. Ensure that all surfaces are clean, dry, and free from any grease or oil.
Tip: Do not allow the first coat to dry completely before applying the second coat.
Asking because I don’t see it specified in the product details. Thanks!
Hi there!
The Penetrating Sealer for AC730 is not matte nor glossy. It is a thin clear liquid that soaks into the AC730 stone. (similar to water or very thin oil). It then dries over 24 hours with minimal to no change to the stone finish, and it is recommended to repeat this process twice. The Penetrating Sealer will allow the piece to be more water repelleing.
Super facile à appliquer !
Fonctionne très bien pour un porte-savon. Invisible.
I really love jesomite, I wish I could get whosale or discount when buying in big orders , I keep ordering but I see I need more and more !! When I use the black and sand the bottom it seem like gray and not black like the mixture . Maybe I need to use an exact amount of pigment or that I’m doing something wrong but I don’t know . I is really hard not to have bubbles , what can I do to have less bubbles?
I really love it anyways !! The best !!
Hi Jashe!
Please reach out to sales@madmayker.com for details on wholesale accounts if you’re using large quantities.
To help with your questions - you can avoid bubbles in a few ways, first ensure you are using a Jesmonite High Shear mixing blade when mixing so you don’t introduce air into your mix. When pouring, gently tap your molds to encourage settling, or encourage the use of a vibrating plate. You can also brush a coat of Jesmonite on your molds first to avoid bubbles in your outer layers.
When sanding black - you may need to wipe off sanding dust - you can do so with a damp cloth. For a deeper black, you can experiment with adding a little bit more black pigments to get the results you’re looking for!
We’re glad to hear you’re enjoying working with Jesmonite!
