Can I Skim Over Plaster the Next Day?
Skimming is the process of applying a thin layer of plaster to create a smooth, even finish. If you’ve already applied a coat of plaster and are wondering whether you can skim over it the next day, the answer depends on several factors, including the type of plaster, drying conditions, and the preparation of the surface.
Factors to Consider Before Skimming Over Plaster
1. Is the Plaster Fully Dry?
Plaster needs adequate drying time before skimming over it. Standard multi-finish plaster takes around 24–48 hours to dry under normal conditions, but humidity and temperature can impact drying times.
2. Surface Preparation
- If the plaster is fully dry: You’ll need to apply a bonding agent like PVA to help the new layer adhere.
- If the plaster is still slightly damp: A second coat may adhere without additional bonding agents, but ensure it’s not too wet.
3. Type of Plaster Used
- Multi-finish plaster: Can usually be skimmed over the next day with proper preparation.
- Bonding coat: Typically requires a PVA or SBR bonding coat before applying a new skim layer.
- Lime plaster: Requires much longer to dry and should not be skimmed too soon.
How to Skim Over Plaster the Next Day
If you need to skim over plaster that was applied the previous day, follow these steps:
- Check Moisture Levels – The plaster should be firm but not overly damp.
- Apply a PVA Coat – Mix PVA with water (1:3 ratio) and roll it onto the surface. Let it dry slightly until tacky.
- Mix the Skim Coat Properly – Ensure the plaster is smooth and lump-free.
- Apply the Skim Layer Evenly – Work in smooth, sweeping motions with a trowel.
- Smooth and Finish – As it firms up, go over the plaster with a clean trowel to achieve a polished look.
Potential Issues with Skimming Too Soon
- Poor adhesion: Skim plaster may not bond well if the surface isn’t properly prepped.
- Cracking and peeling: Applying skim to overly damp plaster can cause future cracks.
- Uneven drying: Moisture trapped between layers can lead to inconsistent drying times and imperfections.
Should You Hire a Professional?
While skimming can be done as a DIY project, achieving a perfect finish requires skill. A professional plasterer ensures: ✔ A smooth, even surface. ✔ Proper bonding and long-lasting results. ✔ Efficient and mess-free application.
