Title: Understanding Plaster Drying Times: Factors and Considerations

Updated: Jun 15



Delving into the intricacies of plaster drying times can shed light on a commonly pondered question in construction: How long does it take for plaster to dry? However, the answer isn't a one-size-fits-all solution; numerous variables influence drying times, warranting a closer examination.



Average Drying Times: When it comes to plastering onto plasterboard, the approach taken significantly impacts drying time. Skimming walls with plasterboard, for instance, necessitates the use of waterproof plaster containing polymers, extending drying time to approximately 2-3 days.


Conversely, plastering onto a solid background like bonding or cement render requires more time, typically around 5-6 days for drying.

Maintaining an optimal temperature below 41 degrees Fahrenheit (5 degrees Celsius) is paramount for expediting the drying process and minimizing the risk of cracking. Conversely, higher ambient temperatures can prolong drying times, affording more time for precision in plaster application.


Why Patience is Key: Patience is indeed a virtue, especially when it comes to painting newly plastered walls. Waiting for complete drying is imperative before applying paint, as most paints seal the wall surface. Painting over damp walls can lead to condensation and moisture buildup within the wall structure, compromising the integrity of the plaster.

Factors Influencing Drying Times: The drying time of plaster hinges on various factors, including the number of plaster layers applied, the presence of plasterboard, humidity levels, and ambient temperature. Each of these elements contributes to the overall drying process and warrants careful consideration.


Determining Dryness: Throughout the painting process, plaster undergoes several stages, from bone dry and crumbly to dry and rubbery upon paint application. Observing these transformations can provide insights into the plaster's readiness for painting. A uniform, dark brown coloration sans visible grains indicates readiness, while lighter patches may signify the need for additional drying time.



Weather's Role: Weather exerts a significant influence on plaster drying times, with summer typically facilitating faster drying compared to winter. Cold weather, characterized by higher moisture levels and lower temperatures, slows drying, necessitating additional time for completion. Conversely, exposure to direct sunlight can hasten drying but may also lead to cracks, underscoring the importance of temperature regulation during plastering projects.

Drying Times for Various Plaster Types: Different plaster types boast distinct drying times, each catering to specific construction requirements. The following table provides an overview of drying times for various plaster types:
