There are few things in the home that make a homeowner’s life more frustrating and costly than making an ugly floor look as good as it can. Whether it is the driveway or the sidewalk that has received some treatment, how to encapsulate black mastic before applying a new application is necessary to avoid future problems. Black mastic is often used to butt up tiles and to anchor carpeting to the subfloor. When mixed with water, the compound hardens into a rigid agent that when applied to floors, ceilings, and other smooth surfaces produces a tough layer of surface with excellent adhesion properties. It also insulates against sound transfer from floor to ceiling.
How to Encapsulate Black Mastic When cleaning a tile or carpet floor, homeowners should pay special attention to the subfloor, which contains most of the material that tiles and carpet are made of. Mastic often sets in dark places such as between tiles or in the spaces between carpet edges. Special tools called “smooth-screws” are needed to loosen and remove black mastic if necessary. Also, any cracks or rough areas should be lightly sanded with drum sandpaper to smooth out the surface.
To encapsulate black mastic before laying a new application, a couple of basic supplies are needed. An empty paint container with a small bit of glue for mixing, an old sheet of metal foil, and an angle grinder with small grinding stones are all that is needed to complete the job. The glue and metal foil must be placed in the container before starting. Do not mix the adhesive or grout mixture with water as this will prevent a good bond.
The next step in how to encapsulate black asbestos mastic is to prepare the subfloor by clearing all debris off the area. A pressure washer is then needed to perform a gentle agitation process to loosen and remove all loose materials. Once the subfloor is clear, the adhesive can be applied with a sponge or a rag. The width of the area will determine the amount of adhesive to be used. As a rule of thumb, one-fourth of an inch of adhesive is sufficient to cover a four foot wide floor area.
Once the new application of the mastic is dry, a trim is needed to surround the newly encapsulated floor. The trim is made from strips of black asbestos mastic and should be about one quarter inch thick. A rubber underlayment is then necessary to provide additional strength and stability to the newly encapsulated floor. The underlayment is often referred to as “spacer” or “cement” because it serves to increase the overall stability of the floor. When combined with the adhesive, the underlayment helps to keep the flooring in place even after it has been applied. It also creates a smoother surface when the tiles have been properly installed.
The final step in how to encapsulate black mastic is to apply the grout. Typically, this step involves rolling out the grout to make it uniform and smooth. This allows easier movement between tiles during the tile installation process. Some products recommend using a very fine grade of grout. Other products recommend a coarse grade of grout to help seal the seams between tiles. A coarse grout will also ensure that the floor dries faster when it is wet.
Once the grout has been installed, you should clean up any debris left over from the application of the cement. If there are large pieces of asbestos tiles, you may want to consult a contractor who specializes in how to encapsulate concrete to see if the pieces of asbestos are safely removed. It is important to only use a damp cloth or sponge when removing large pieces of asbestos. Asbestos is very flammable and if exposed to flames or heat they could be released into the air. You may also want to wear protective gloves and eye goggles while handling the vinyl tiles.
The installation of an encapsulation system on your floor will help prevent the formation of mold and mildew on the floor. It will also help prevent damage caused by water seepage and cracks caused by heavy traffic. If you think you might have problems with asbestos or another type of asbestos-containing material at your home, be sure to contact a competent licensed contractor who can complete a full assessment and complete the job of how to encapsulate your floors.
