Structo – Lite ® Basecoat Plaster is mill-mixed, perlite-aggregate gypsum that weighs half as much as sanded basecoat plaster and provides thermal conductivity.
Will Structolite stick to drywall?
However, StructoLite does not. It sticks to plaster without issue, but it has an issue with drywall. It’s similar to the stuff that comes pre-coated when you buy Blueboard drywall. It gets applied to the drywall with a standard paint roller and must be allowed to dry before applying the plaster.
Can you sand Structolite?
The Durabond 90 will produce a gorgeous smooth finish that will match the existing plaster, and it’s sandable. Real white lime plaster can ‘t be sanded because it’s so hard. Mix the Durabond 90 with cold water to extend the working time. You apply this as you would normal drywall joint compound.
How do you use structo-Lite?

Can you sand base coat plaster?
Base coat is harder than top coat, so when sanding, if you try to sand out a bump of base coat, all you succeed in doing is sanding off all the top coat around the bump, making the bump worse not better! The purpose of sanding is to make the join invisible.
Can I use joint compound over Structolite?
You apply this as you would normal drywall joint compound. Mix it to the consistency of warm cake icing. Try to put it on over the Structolite so it’s extremely smooth and free of surface defects. Be sure it’s in the same plane as the surrounding plaster.
How long does it take Structolite to dry?
My front parlor took a full year to restore but easily seventy-five percent of the original plaster is still there melded indistinguishably into the replaced Structolite areas with a rather thick ONE coat of the product. It takes overnight to dry.
What is base coat plaster?
Base Coats are a setting type jointing compound that provides superior tape adhesion and joint strength. They are used for the first and second coat in a three coat jointing system, along with jointing tapes. Joints may be finished with any Gyprock topping or all-purpose compound and sanded smooth prior to decoration.
How do you make Structolite dry faster?
3 Answers. The Structolite is drying out too fast, because the bare brick is wicking out all of the moisture. You need to use a bonding agent and possibly add some sand to your base coat, as well as scarify it, for any successive coats.
Does joint compound stick to plaster?
All-purpose joint compound is a building material drywall finishers use to spackle, or mud, a drywall installation. All-purpose joint compound adheres well to most surfaces, so you can use it to make repairs on plaster walls.
Do you need to seal new plaster?
You first need to seal new plaster to make it less absorbent and to help the topcoat adhere better. A common way to seal it is with watered-down emulsion (known as a mist coat), as the plaster sucks up the water and becomes less absorbent.
