Step 4:

Now that it is the next day and the glue is dry it is time to texture them. You will need your large paintbrush, the black latex paint, the sand and a tarp to work on.

First lay the tarp on the floor so you will have somewhere to collect the sand as it falls off the boards. Lay the boards on the tarp and brush on a thick coat of paint onto the top flat surface of one board. Once that is done, poor the sand onto the paint you have just put down. If it is particularly warm you may want to do a small section at a time.

At this time I also painted all the little “islands” and put sand on them too.

Once the first board is done, repeat the steps on the other two boards. They will need to sit for a few hours to let the paint dry all the way.

When you come back in a few hours tip the boards over onto the tarp to get all the loose sand off. Use the tarp to poor the sand back into the bag or a container for use later.

Now you need to paint the vertical edges of the lava field and put sand on them. Be careful not to get too much paint down on the lava channels. You can cover up the little bits of sand that will stick down there when you do the lava itself. Once all this is done and had had a chance to dry go ahead and shake off the sand again and put the extra back in the container.
