This provides an inexpensive and easily producible product with predictable properties, but has the downside that the results, while vapor open (letting water vapor through), are water sensitive. Normal drywall (sheetrock, plasterboard) consists of a gypsum-and-fiber core that is pressed between sheets of heavy (construction) paper and then dried together. To understand paperless drywall, you need to understand paper drywall Additionally, I would think that a water proof membrane for the shower surround would also render it vapor proof, but I've been wrong before. It has been my understanding that cement board (with a waterproofing membrane of some sort) was the appropriate backer for a tile surround, and this now has me questioning that assumption. Would the fact that one of the surround walls in the question that answer was provided on was on an exterior wall make any difference in the application of this advice? ![]() What are the differences between a "paperless drywall" and regular drywall (I've never seen "paperless drywall" at my local big box store, so would have to expand my life experiences if I were to go looking for it) and cement board in terms of their use as a backer behind a tiled tub/shower surround? Remember to always refer to the compound manufacturer’s instructions for recommended drying times.I would recommend paperless drywall over cement board for the tub surround, as well - gypsum board of all types is vapor open (around 50 perms) while serving as an air barrier, allowing drying to the inside without letting a ton of humid air into the wall cavity, while cement board is a fairly severe vapor retarder at 4-8 perms, which puts more pressure on the ability of your tub surround to keep water out of the wall to begin with. We suggest staying away from lightweight compounds when embedding any type of tape. Taping and setting compounds are also great to use with our FibaTape and FibaFuse products. FibaFuse works with all compounds but we also recommend heavy weight all-purpose if you prefer all-purpose compound. If the temperature is warm and stable and humidity is low you can also use the heavy weight compound with our other FibaTape products. Weight all-purpose ready-mixed compound for those that prefer all-purpose compounds. When taping regular, tapered edge seams with Perfect Finish or Extra Strength tape we recommend heavy What type of compound should I use with FibaTape/FibaFuse?Īlthough FibaTape and FibaFuse products can be used with all types of compounds, we do have some recommendations for the best results. Where are FibaTape and FibaFuse products manufactured?Īll our FibaTape and FibaFuse tapes are made in the USA except for Perfect Finish which is made in Sustainability reports exist for both FibaTape and FibaFuse products and are available upon request Where can I find LEED information on your FibaTape and FibaFuse products? While you can use a taping knife, we suggest using a corner trowel for installation to prevent cutting the tape. 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. FibaTape does make a special tool for placing the tape into the inside corners. So when a taping knife is used to apply and smooth the joint compound the taping knife could accidently cut through the tape. ![]() If it is rounded then it is not tight into the corner. Make sure the tape is tight into the corner without being slightly rounded. The tape is self-adhesive so it can be applied to all the inside corners before any joint compound is applied. Just fold it with one hand and press into the corner with the other. FibaTape can be used to tape inside corners. Compatible with automatic taping tools or hand toolsĬan I use FibaTape or FibaFuse on an inside corner?.Ideal for use in mold-resistant drywall systems.GREENGUARD Gold Certified for a safer environment.Thin profile provides a smooth, professional finish. ![]() Open-fiber design eliminates blisters, bubbles, and dry spots common with paper tape.The open-fiber design fuses with joint compound creating a better bond and stronger joints. FibaFuse, the original paperless drywall tape, is a mold-resistant joint treatment that makes it easy to achieve professional results with superior performance.
