Cracking compound is used to fill cracks and imperfections in surfaces before painting or wallpapering. It comes in two forms, ready-to-use and powder, and is made of gypsum plaster and glue. Different types of spackle have different purposes, such as creating a smooth surface or covering imperfections in vinyl wallcoverings. All types require sanding after drying for a smooth finish.
Cracking compound is a material that is typically used to fill cracks and imperfections in surfaces before painting or wallpapering. Gypsum plaster composed of hydrated calcium sulfate and glue are its main components. It usually comes in two forms: a ready-to-use variety that is mixed to a consistency that is generally used for most repair jobs, and a powder to which water is added to make a thick paste. The powdered form is often used as a joint compound so it can be made thicker to cover butt joints on drywall.
The typical purpose of spackle is to create a smooth, flat surface so that it won’t sag or have an indentation when you apply wallpaper or paint to the wall. This is done by filling a hole, indentation or crevice with the compound and allowing it to dry completely. Many renters use spackling compound when leaving a unit to fill small holes in walls from nails, screws, or molly bolts that they used to hang pictures and mirrors. This procedure usually provides a quick and clean wall, helping the renter recover his security deposit.
The poultice compound should be allowed to dry completely so it doesn’t crumble when you apply paint or paper over it. Some brands are colored so it’s easier to see the difference between when they’re wet and when they’re dry. This type typically comes in ready-to-use form and is pink when wet, but turns white to let the user know it’s time for the next step. This was created because some walls require a thicker application due to the depth of the crack, hole or indentation and require a longer drying time.
Vinyl putty is often used to cover imperfections in vinyl wallcoverings. This step usually allows a homeowner to apply a second sheet of wallpaper or other wall covering directly over the original layer without incurring the time and cost associated with removing the original. All types and shapes of spackling compound usually need to be sanded after drying to ensure a smooth surface. This can be achieved with a sheet of sandpaper on a sanding block for small areas, although a belt sander may be easier to use on large areas.
