I am also having some difficulties and I was thinking of spaying a coat of fixative for acrylic paint over the sand...
Cheers, Annie

The sand gave me difficulty, too, Annie.  I think it's best to let it dry a few days before putting paint over it.  Mine is now a week old and rock solid.

Michelle,

I had sand all over the place for days.  Now that it is a week old, it is permanently adhered to the surface.

I use DAP all purpose spackling paste from Home Depot.  Once it dries, it's rock solid.

If you apply the paste, then a thick layer of sand, then press it down (sheet of waxed paper and a heavy book over it for a few minutes), that should get all the sand into the paste.  Then let it dry a few days before proceeding.

If I were going to do it again, that's how I would do it.  Hope you can benefit from my mistakes.  Good luck

Tip:
After walking over tiny beads all over the studio, we used a cheap cafeteria tray to catch the sand this am.  It did a good job to keep the sand under control.

Good thinking on using the cafeteria tray. 

Expanding that line of thinking, even an old cookie sheet (with sides) would work.

Necessity is the mother of invention!!!

To get the sand to adhere, be liberal with your texture gel so that the sand has enough gel to get stuck to, then sprinkle the sand itself on liberally too. Rather too much than too little. Leave it a while then gently tip off the excess. Once that is dry, check to see if the canvas is still visible, if it is, repeat the process. Eventually the thickness of the sand will hide the canvas below it giving you one even colour. You can then seal the sand with one last coat of gel.

Unfortunately it is a mission to keep the sand from going all over the show. A serving tray will work well to catch the sand when you lift the canvas, if you don't have one you could fashion a catch / tray using aluminum foil

I have tried a number of combination to see what works best to stick the sand onto the canvas. See attached but in summary (and Nolan would know) they are worked equaly well. 

Minimal advantage of using a varnish spray for acrylic (Kamar Varnish from Krylon, allow rework) was that it fixed most of the sand without lifting any off.  Saying that, not sure it is worth the vapour and smell!

As for the top coat, same results just more or less shiny, depending if gloss or matte gel was used.

Here is anothe tip... if you only have a few spots where the canvas show...it maybe the perfect places for a shell!

Here is my testing:

I used modge podge on the canvas, I brushed it on and then poured the sand over it. Then I tapped off the access sand and with a brush using it flat, like when we paint layers I brushed on modge podge over the sand. I then only left it to dry, it took about a day. Then I painted over it where needed. I had no problems at all.

I am intrigued with the texture gel you all are using on this painting...

What exactly is it? Acrylic based? Silicone based? Something else?

What brand are you all using?

Is it clear?

How thick is it?

Does it hold it's shape good if you are making it 3D like texture paste?

Or do you need to build it up?

How does it bond to acrylic paint?

Thanks!

Jeannie,

I use DAP all purpose spackling paste from Home Depot.  When dry, it is very hard - even a thin layer is hard to crack.

I am pleased.  it worked well for me and is relatively inexpensive - less than $5.00 for a small tub.  Think it's vinyl based.

DAP has another product called DRYDEK - it's more expensive but may dry even faster.  Will check it out.

Hope that helps.

Oops, Jeannie, I forgot to answer the rest of your questions.

Is white and dries white. 

Takes acrylic paint beautifully. 

It's a thick paste, but spreads smoothly.  I let it set a couple minutes then curled up the tops of the waves and they stayed in place.

Hope that helps.

My submission for this lesson. This is on a 16x20 inch stretched canvas. Since I didn't have access to sand I used sand I found in the floral supplies at Michaels. A little fine for my liking. I have put 2 coats with sand and then a final coat of gel. The fine sand is still coming off a little.  Should I put an additional coat of gel over the sand??   :heeha: :heeha:  suggestions for improvements are welcome

This is beautiful Sherri! Your foam looks fantastic!
I used the same type of sand also and it is a bit fine. I had to use a couple layers of sand like you did and an extra layer of gel to hold it all down  :)

Thanks Denise. Do you still have a little sand coming off?
