Faster, cheaper and smoother than cement. Here's everything you need to know.
Cement plaster has been the default for decades. But builders and homeowners who switch to gypsum consistently report three things: the job finishes faster, it costs less in total, and the walls look better.
Gypsum gives a smooth, paint-ready surface without a putty coat. It sets in hours, not weeks. And it uses zero water for curing.
The one exception: bathrooms and external walls. Use cement there. For everything else โ internal rooms, ceilings, corridors โ gypsum wins every time.
