Step 6. Remove dust over the drywall
Remove the dust over the drywall with the help of a drywall mop by wiping the dry mop up and down. All surfaces must be structurally sound clean, dry, and free from contaminants that would prevent a good bond.
Step 7. Apply primer
Always apply the best primer to cover drywall imperfections on bare drywall with the help of a paintbrush, roller or spray because drywall is made up of porous materials like gypsum, and that’s why it absorbs the solvent from any material which you apply.
So you won’t get a better result that’s the reason always apply primer on bare drywall. Primer seals the drywall properly and prevents it from mold. Now let them dry. Want to know more about primer then read this post Painting drywall without primer.
After drying of primer, apply drywall tape and mud over the drywall joints and let them dry. After drying, sand over there with the help of a drywall sander.
Then wipe down the dust with the help of a drywall mop. Now apply primer again, over the sanded area only, and let them dry. If you want to drill down the primer then check this post Do I need to prime drywall before tiling.
Step 8. Apply Lapage 2 in 1 sealant
Apply Lapage 2 in 1 sealant on the side and bottom corner of the drywall and after applying sealant, gently press it with your index finger and drag your index finger down so that you will get the smooth finish over there.
In this way, you can completely seal the drywall so that there is no chance of moisture or water enters into the drywall.
Step 9. Apply Waterproofing
Pour the RedGard waterproofing into a clean paint tray and load the roller.
Apply loaded roller onto the drywall and roll the Redgard waterproofing material onto the drywall. Use the paintbrush for areas that are unreachable with the roller.
Apply a good coat of Redgard to all the corners. Now apply a 6-inch wide fiberglass mesh into the wet RedGard to all the corners of the drywall and then again cover with subsequent coats as normal.
And let them dry, when it is dried completely then this Redgard turns pink to dark red color so you came to know that the Redgard is completely dried. Typically it takes 60 to 90 minutes but it also depends on the ambient conditions.
After drying your drywall is completely ready for further work. Now if you want to tile over there, you can. If you want to know more details about how to tile over drywall then read this post Can you tile over drywall in the shower.
