What type of compound should I use with FibaTape / FibaFuse?

Although FibaTape and FibaFuse products can be used with all types of compounds, we do have some recommendations for the best results.

When taping regular, tapered edge seams with Perfect Finish or Extra Strength tape we recommend heavy weight all-purpose ready mixed compound for those that prefer all-purpose compounds.  If the temperature is warm and stable and humidity is low you can also use the heavy weight compound with our other FibaTape products.  FibaFuse works with all compounds but we also recommend heavy weight all-purpose if you prefer all-purpose compound.  Taping and setting compounds are also great to use with our FibaTape and FibaFuse products.  We suggest staying away from light weight compounds when embedding any type of tape.  Remember to always refer to the compound manufacturer’s instructions for recommended drying times.

How do I apply FibaTape?

FibaTape drywall tapes are self-adhesive fiberglass mesh tapes. As long as the surface is dry and dust free the tape will stick by pressing into place by hand or with a taping knife. The tape is now ready to be coated with joint compound.

Does FibaTape need to be embedded?

Yes. FibaTape has to be embedded in joint compound but not in the same manner as paper tape or FibaFuse tape. FibaTape is self-adhesive and should be pressed into place over the seams or in inside corners before any joint compound is applied. The compound is applied over the tape and because it is a mesh tape the compound actually is forced through the tape. This is one of the reasons for the popularity of FibaTape, the ability to put all the tape in place and then embed.

What tape should I use on cement board?

Cement board or similar products are typically the substrate for tile which is often set in a thin-set type mortar. FibaTape Cement Board Tape is alkali-resistant and the only tape that should be used for cement applications with dry or thin-set mortar. This tape is made from the same vinyl-coated fabric that is embedded in the face of some cement boards to give the board added strength and crack resistance.

Can I use Mold-X10 on cement board in my shower?

No. The Mold-X10 fiberglass mesh tape is made for drywall seams and intended to be coated with joint compound. FibaTape’s Cement Board Tape is the product for cement board.  The alkali-resistant coating protects the fiberglass from degradation that can occur with thin-set mortar.

Which tape do I use where cement board meets green board?

The best tape to use if the seam connecting the green board to the cement board is Mold-X10 if the seam is going to be coated with joint compound. This would be done if the seam will not be covered with tile, which means it has to be properly concealed with joint compound so that the area can be painted. If the seam is going to be covered with tile which is most likely the case then use FibaTape’s Cement Board tape. The seam will then be coated with thin-set as the tile is applied.

Can cement board tape be used on regular drywall?

No. Cement board tape is made to be embedded in thin-set mortar not joint compound.  We do not suggest using it on regular drywall.

Can I use FibaTape or FibaFuse on an inside corner?

Yes.  FibaTape can be used to tape inside corners. Just fold it with one hand and press it into the corner with the other. The tape is self-adhesive so it can be applied to all the inside corners before any joint compound is applied. Make sure the tape is tight into the corner without being slightly rounded. If it is rounded then it is not tight into the corner. So when a taping knife is used to apply and smooth the joint compound the taping knife could accidentally cut through the tape. FibaTape does make a special tool for placing the tape into the inside corners.  The dispenser type tool holds a roll of tape and actually rolls the tape tight into the corner and cuts it to the desired length. A must have tool for larger taping jobs.

FibaFuse is pre-creased for corners.  While you can use a taping knife, we suggest using a corner trowel for installation to prevent cutting the tape.

What is the best way to use FibaTape when repairing cracks in plaster and is one particular version of FibaTape preferred?

Just sticking FibaTape over the crack and concealing with joint compound may work, but most likely the crack will return to some degree. Creating a V groove along the crack will allow you to actually fill in the crack and repair deep into the crack. The extreme cracks should be covered with Extra Strength FibaTape. The tape can be applied over the V groove and when compound is applied make sure to apply enough pressure with the taping knife to force compound through the tape filling the V groove. You could also prefill with compound and cover with the tape. Perfect Finish™ FibaTape is also good for the repairs because it is quite strong and is also the thinnest product making less of a bump for an easier to conceal repair.

When do I use FibaFuse Wall Reinforcement and when do I use FibaTape Super Crackstop™?

Both products really accomplish the same thing. It would be a matter of personal preference. The FibaFuse is embedded in compound that is applied first. The Super Crackstop is self-adhesive and is applied to the wall or ceiling first and is then coated with joint compound.
