What is GoBoard?

GoBoard is the brainchild of Johns Manville, designed to be a lightweight yet robust backer board. Its composition features a high-density polyisocyanurate foam core sandwiched between coated fiberglass mats. This structure not only makes GoBoard incredibly light (about a fraction of traditional cement boards) but also ensures its high waterproofing capabilities. Whether you are tiling a shower wall or a tub surround, GoBoard has got you covered!

  • Superior Waterproofing: Unlike cement boards that may absorb moisture, GoBoard is designed to keep water out, making it a superior choice for wet areas like showers. The built-in waterproofing means you can toss additional membranes out the window!
  • Time-Saving Installation: You can cut GoBoard with just a utility knife without dust clouds forming everywhere. PLUS, the fastener installation is straightforward and quick GoBoard vs. Cement Board Shower Installation.

3. Preparation Steps

Ready, Set, Prep!

Before diving into the fun stuff, it’s crucial to prep your workspace. This sets the foundation for a successful installation:
  • Remove Old Surfaces: Get rid of any old tiles or surfaces carefully, making sure you’ve stripped it down to a solid foundation. You don’t want to start from a shaky point.

The Installation Fiesta!

5.1. Applying the First Board

  • Before you set that first board, apply a proper bead of sealant along the edges. This ensures a tight seal and helps in waterproofing.
  • Align the board flush against the wall to keep it neat.

5.2. Fastening GoBoard

  • Make sure to use the recommended GoBoard fasteners, spaced adequately—about every 8 to 12 inches for secure holding. Follow the GoBoard Shower Pan Kit recommendations for best outcomes.
  • Fastening should be done properly to avoid any damage. It’s all about finesse, folks!

5.3. Sealing Joints & Edges

  • Take your time sealing the joints. It’s ACIDIC STOP! You want to prevent any water intrusion down the line.
  • Use fiberglass tape at seams for added strength. This will hold everything together like a champ.

6. Tiling Over GoBoard

Let’s Get Tiling!

Once your GoBoard is installed, it’s time to add some flair:
  • Choose appropriate tile adhesive and tiles designed for wet areas. Always double-check compatibility!

  • Ignoring Tiles Weight Limits: Some tiles are heavier. Make sure your backing can support them!

Keeping Your Shower Fresh!

Once you’ve completed the installation, it doesn’t end there:
  • Regular Inspections: Check seals and grout lines to ensure they remain intact. Early detection can save you BIG headaches later.

Your Go-To Guide for DIY GoBoard Shower Installations

Before diving into your shower project with GoBoard, you’ll need some AWESOME tools to make the process smooth. Check out this list of essentials to have in your toolkit: 1. A utility knife for cutting GoBoard easily. 2. Drill for fastening the boards. 3. Mixing paddle to blend your adhesive or mortar. 4. Several buckets—I suggest at least three! 5. A trowel for applying mortar. 6. Grout and grout sponges to finish the tile edges. 7. A straight edge to ensure nice straight cuts. 8. A wet saw is crucial for cutting tiles, especially when you need a clean edge. For a full rundown of tools and their usage, you can see more details here.

Measuring & cutting your GoBoard is a game-changer for ensuring FIT and finish. Start by measuring the height & width of your shower space. Add a couple of extra inches to your measurements for a snug finish. When it comes to cutting GoBoard, simply use your utility knife. Score the board deeply along your measuring line, then bend it at the score line until it snaps easily. For detailed visuals, you can check out more about the cutting process here!

When it comes to fastening GoBoard, you won’t want to skimp on the right materials. The gold standard recommendations include using GoBoard® fasteners that are 1¼" long along with GoBoard® washers. Alternatively, 1½" long galvanized roofing nails or 1" x 1" garden staples (16-gauge) work like a charm too! This combo will secure your board to the studs without any hiccups. For more in-depth details, check the Johns Manville GoBoard fasteners documentation.

It’s a tricky question! GoBoard already has a built-in waterproof feature, so many DIY warriors find that it performs fabulously without additional membranes. However, if you want that extra peace of mind—or if there are tricky joints—consider applying a waterproof membrane like the Kerdi membrane over the GoBoard to enhance your setup. For an exhaustive take on waterproofing, check out this discussion on Reddit.

Sealing your GoBoard joints is key for achieving a WATERPROOF finish. After installing your GoBoard, fill fastener spaces and seams with a quality sealant. Using a caulk gun, apply sealant into the joint, ensuring a smooth and even line. Don't forget to smooth with a finger or tool to get a neat finish! For an in-depth review of the sealing process, see the GoBoard installation guide.

Absolutely! GoBoard is suitable for steam showers, but here’s the kicker: ensure any joints and seams are perfectly sealed. Use a solid waterproof sealant to prevent steam and moisture from sneaking through. Also, consider additional ventilation to reduce moisture buildup. Want the low-down on steam applications?

Installing a GoBoard shower pan kit is a piece of CAKE when followed step-by-step: 1. First, prep your subfloor, ensuring it's level. 2. Position your shower pan in the designated area. 3. Secure the pan with mortar following manufacturer instructions. 4. Then, cut your GoBoard to fit the walls, leaving enough overlap for the pan. 5. Fasten the GoBoard to your walls with the appropriate fasteners. 6. Remember to seal joints before tiling! For more visual guidance, watch this instructional video.

Proper drainage is CRUCIAL! When positioning your shower pan, ensure it slopes slightly (at least 1/4 inch per foot) toward the drain. Check that the GoBoard is level with a trusty level tool, adjusting as necessary at the go. Ensuring that your pan is installed correctly with this slope will significantly help water flow away efficiently. For detailed tips on drainage, the official Johns Manville GoBoard website is a great resource!

Avoiding rookie mistakes can save your shower build from disaster! Here’s a handy list: 1. Forgetting to seal seams properly can lead to leaks. 2. Not sloping your shower pan correctly. 3.

Be sure to research and take care! For more pro tips, you can find great advice in discussions on Reddit.

Surface prep is key to a successful installation. Start by ensuring the wall is free of dust, dirt, & old materials! Make sure the framing is secure, sturdy & dry.

For an in-depth review of proper surface prep, you can find excellent tips on YouTube.

When working with GoBoard, choosing the right adhesive matters! You’ll typically want a high-quality construction adhesive like Liquid Nails or Power Grab.

Handling corners with GoBoard can be TRICKY but manageable! Make cuts at a 45-degree angle to ensure a good fit.

If you find your GoBoard is starting to play the buckling game, check for moisture issues. Ensure there are no leaks affecting the substrate. If they’re warped but still structurally sound, you might be able to re-level them or even cut new pieces to fit where needed. For extreme cases, replacement might be your best option to avoid future headaches. For detailed solutions, the ever-helpful Reddit community has insights here.

The reuse of GoBoard is a bit hit or miss. If taken down without damage, it can potentially be reused, but keep in mind that it may have irregularities from the removal process. This could affect how it adheres during reinstallation. Always inspect closely before making a decision! You can find experiences about this topic in multiple threads on Reddit.
