Step 6: Varnish your table
If you had any areas to fill with rocks, you'll now want to sand the table top flat before adding varnish.
Then use a cloth or vacuum to remove all traces of dust. Be sure to clean well as you'll see any dirt after varnishing.
Now that your table is cleaned, you can mix another batch of varnish and begin brushing the varnish on the table. I always start with the less flat areas, and all the nooks and crannies. Leave the flattest parts to do last to ensure the smoothest result.
If you're using the recommended varnish, you'll see that it suggests using a propane torch to heat the varnish to remove air bubbles. Follow the directions on the product you are using. If you use a propane torch, be careful not to scorch or burn your table. Keep the flame moving!
Once the entire table is coated with varnish, allow it to dry.
After your table has dried, you should be able to see if you missed any areas and if you require another coat. This is also your opportunity to correct any problem areas (like un-vacuumed dust that you can see) by sanding any areas as needed, then reapply your varnish.
Once your 2nd coat is done, allow your table to dry undisturbed until fully cured. Check your varnish package for the recommended amount of drying time. You don't want to place anything on your table until you are certain the varnish is cured and dry.
Congratulations! You have now made your very own one of a kind table.
