Various compound textures have been applied to hide minor surface imperfections. Drywall installers use different mud fillers for different stages of the process. Keep intact as we peruse some of the application similarities and differences of texture mud and joint compound on the drywall.
Drywall installers may use different mud compounds for embedding paper tape, setting a base layer to cover the tape, and topping the joints. Drywall installation conceals stains, repaired areas, and surface imperfections.
A joint compound is also referred to as drywall compound or Mastic. The drywall compound is a white powder of gypsum-based paste. The gypsum dust is mixed with water to form mud, the consistency of cake frosting.
A joint compound is usually available in the form of a wet and dry compound. Dry joint compound requires mixing with potable water for easy setting and forming workable mud. On the other hand, wet joint compound is pre-mixed and ready to use, especially for residential DIY.
Joint compounds contain latex additives to add strength and flexibility on surfaces. The consistency of the joint compound depends on the ultimate purpose. Ensure the gypsum-based paste is a little thicker for final coating or has pudding consistency properties for hand tapping.
The joint compound mud is available in varying basic types. The joint compound types can be used as a single type or combination to attain the desired results. Some of the common uses and applications of the joint paste include;
- Joint compound is used with paper or mesh joint tape to seal joints between sheets of drywall. The seal creates a seamless base for paint on interior walls.
- The paste is used to finish drywall joints and corners in new drywall installations.
- It is handy for repairing cracks and holes in plaster surfaces and existing drywall.
- The wet mud material is used to fill joints for plastic and metal corner beads.
Types of Joint Compound
The all-purpose compound is lightweight, easy to work with, and has a slow drying time. It is ideal for coating the first three layers over drywall joints. This is the best drywall mud as drywall installers can use it for diverse phases of drywall finishing, such as;
- Embedding joint tape and filler coats
- Texturing and skin coating
This is a soft low-shrinking compound that offers a very strong bond. The topping drywall mud compound is best for final coats. It works great after the first two coats of tapping compound.
The topping compound is usually available in dry powder; hence requires to be mixed with water for easy workability. It is not recommended for embedding joint tape. Using the topping compound as the final layer reduces the sanding time.
The drywall mud compound is ideal for embedding joint tape. It is best applied to cover plaster cracks because it dries harder. More so, it is an ideal option for laminating drywall panels in ceilings and multilayer partitions. Tapping compounds offer crack-resistance properties, and it isn’t easy to sand.
It is also recognized as hot mud. If you seek a compound that is crucial to quickly enhance the completion of a job, a quick-setting compound is a deal, especially if you want to apply multiple coats in a single day.
This compound is useful for filling areas where dry time is an issue, such as deep cracks and holes in plaster and drywall. Additionally, a hot mud compound is great in areas with high humidity.
Unlike other compounds set by simple water evaporation, quick-setting compounds are set by chemical reaction. Hot mud compounds can be set in damp conditions.
The quick-setting compound is available in the form of dry powder. It is mixed with water and applied immediately. The setting time ranges from five to ninety minutes.
Texturing mud compound is known for its ability to hide mistakes on drywall. It is a compound with a substantial and subtle appearance on the surface. Specialized texture mud comes in powder or spray form.
The texturing material can be applied on a surface via spraying with a hand sprayer or by spreading the texture on drywall with a knife then scraping it lightly. Use the pre-mixed variety undiluted for spreading on drywall. Add water to the compound for easy spraying.
While using texture mud, you may add sand to the compound to add graininess to the texture. The finer grains provide firm ground, especially to the ceiling. Allow the compound to stiffen for about one to two hours before you scrape it.
Texturing a Wall
Wall texturing provides an overall stunning new look in a room. Various techniques for spreading texturing compounds create varying final patterns. Although you may need some preparation before texturing over oil-based paint, texturing can be done right over the old paint.
Improve the adhesion by using de-glossers to de-gross the paint. Wash the wall with a strong tri-sodium phosphate solution and let the walls dry. Then etch the painted surface sanding with a pole sander. Spread a coat of oil or water-based primer on the drywall to improve adhesion.
The optimum consistency of texture depends on the mode of application. Let the texture be as thin as paint, especially if you spray or roll it along the wall. Dilute the pre-mixed mud to trowel on the drywall. You can deposit blotches on the drywall surface.
Texture Mud vs. Joint Compound: The Similarities
- Both filler compounds are available in the form of either dry powder or pre-mixed material.
- Both installation material compounds are used to hide imperfections
- Both processes can integrate the use of all-purpose drywall joint compound material in the installation process
- They both create an interesting pattern on the wall
Texture Mud vs. Joint Compound: The Differences
- Joint compound is mainly used for tapping seems, whereas texture mud is used to produce mottled surfaces.
- Joint compound is simple to use, whereas texture mud entails a complicated application procedure.
Drywall texture is used on surfaces to mimic other wall coverings. Selecting the best drywall filler compound depends on the crack or surface imperfection to be repaired. Drywall installers use varying bonding agents and compounds to attain the preferred texture.
