$10 Dry Erase Tables

Let me start off with this.  THIS WAS NOT MY IDEA, I found a post by Sprout Classrooms from 2014 and pretty much followed her directions to a T.

Dry Erase Table Transformation


BEFORE
Primer
AFTER

Time:

Total Time = 5 days
Primer ~ 3 hrs + overnight
Dry-Erase ~ 2 hrs + 3 DAYS cure


Cost:

My total cost was ~$120 for 12 tables
$10 per table!

Materials:

  • Acetone 
  • Lint-Free Rags
  • Latex Primer (indoor)
  • Paint Roller & Pads (2 x smooth finish)
  • Paint Stir Stick (...which I forgot, so an old ruler...)
  • Paint Can Opener
  • Disposable Paint Tray (2)
  • Rust-Oleum Dry Erase Paint (1 kit for 3-4 tables)
  • Tarps or Sheets (to make your custodians happy)

Procedure:

DAY ONE: 

Clean & Prime


Clean
Supplies
Prime
  1. Use acetone on a lint-free rag to clean the table tops.  DO NOT USE SOAP (per the directions on the primer can).
  2. Shake the primer vigorously.  Open, stir completely, pour into paint tray.
  3. Roll primer on to table tops and sides, using a somewhat thick coating.  (I did NOT sand the table tops, once I cleaned them, I went straight to primer and had no issues.)  
  4. DO AT LEAST 3 COATS.  Per the directions on the primer can, allow 1 hour between coats.  The dry erase paint does not have much of a white background, so you want complete coverage with the primer.
  5. Allow to set overnight.
Save any leftover primer for next summer - the original post suggests reapplying before each school year. (I did 12 tables and used 2/3 of the gallon of primer.)

DAY TWO: 

Dry Erase Paint

Product
Combine
Outcome
  1. Shake the dry-erase coating and base paint cans vigorously.  Open each, pour A into B and stir completely.  Pour into paint tray.
  2. Roll dry-erase paint on to table tops and sides, using a thin coating.  (This is a VERY thin paint, be careful with splashing.)  The roller will make it look texturized as you apply, but it does dry to become a slick surface.
  3. DO AT LEAST 3 COATS.  Per the directions on the box, allow 30 minutes between coats. 
  4. Allow to cure for 3 days.
I used 3 boxes of dry-erase paint for 12 tables.  I have a back up box, just in case, but after testing, I didn't seem to need an extra coat, even though I have some "dull" spots.

DAY FIVE: 

In an inconspicuous location, like the side of the table, test your markers.

Test Your Markers!

EXPO - Bold Colors
EXPO - Multi Pack
CRA-Z-ART Dry erase
some residue
all clear
significant residue
  1. Let the marker dry on the surface for about 15 minutes.
  2. Erase.
  3. Use white board cleaner (or water) to clean completely.

My Notes & Opinions:

Overall, I'm amped to try these out with the kids on the first day of school! I think they are really going to enjoy working problems and brainstorming on these tables, rather than in their notebooks.  I can see a lot of jig-sawing and collaboration in their future.

EVERY.  SINGLE.  TEACHER. who stopped by to say hello during pre-planning exclaimed, "WOW!  How did YOU get new tables?!?"  When I told them about the dry erase surface, their envy grew.  Even the custodians, who were justifiably concerned about their newly waxed floors, were pumped.  The white certainly brightens up my window-less lab.

I read that the PINK EXPO markers leave a stain, and although my test pink did not, I am going to pull the pink markers and not use them.  I am disappointed that the Cra-Z-Art markers I found on clearance left such a residue.  I'm not going to be using these with kids.  I'll see how they do on my normal teacher whiteboard, and if they stain there, I'll give them away.  Wah. Wah.

From the blog post by Sprout Classroom, I calculated 4 boxes of Rust Oleum Dry Erase Paint for 12 tables (that are approximately 3' x 6').  I only ended up using 3 of the kits, even with 3 coats.  We will be using the tables regularly and I'll see if we need to add a coating of dry-erase over the Labor Day long weekend.  If not, maybe Christmas break will see a reapply, or maybe right before the end of the school year. (I didn't like using my back to school planning time for this project).

Last, but certainly not least, I tend to be an "ask for forgiveness" person.  However, in this case, I definitely asked for permission.  My principal had to get the go ahead from the county level to "alter school property" so I'm glad I didn't just wing it.  If you'd like a copy of the email, I used Genius Hour Projects as my driving factor, please request it in the comments.

What do you think?  Is this something you will try?
