Everyone has their opinion on plastering finishes and a homeowner can certainly choose whatever finish he/she wishes to have on their home's ceilings (and walls).
Here is why you should refrain from plastering the ceilings (and walls) with any textured finish.
1- Outdated Look
A textured ceiling may have been the thing to do in the past and in some cases recently. But as tastes and trends change over time, the textured look will look outdated and it will diminish the value of the home because a new buyer would look to have the ceiling changed to whatever is the common trend, which nowadays is a smooth finish. In addition, as trends become outdated, certain tools will no longer be available in the event of a needed plaster repair.
2- Damage Repair Difficulty
Continuing from the point above, if you ever end up having water damage repair to your ceilings, if the ceilings are outdated and the type of tools used are no longer available, how would a new plasterer be able to appropriately repair it? It could be a nightmare to repair a textured water damaged ceiling (or walls for that matter). Patching a hole in such situation may be a lot harder to achieve than you may expect. It is always harder to find a plasterer to match a textured finish. Even if you do find someone to do it, it may not match exactly as each plasterer has their own way of plastering and own hand weight to apply the mud. If the professional plasterer is unable to patch the textured ceiling, the alternative would be to smooth out the entire ceiling, which will end up costing you more.
3- Home De-Valuation
Your home will lose value on the long run. When you decide to sell your house, a textured finish will make the house have a lesser market value because the modern trend is to have smooth ceiling finishes (and smooth walls).
4- Residue Hold Up
The grooves or elevated chucks formed with a textured finish (swirl, popcorn), will look gross with time. They can gather dust, grease, mold. Please, NEVER texture finish your kitchen ceiling! One of the top requests we receive is to smooth out kitchen ceilings in older homes.
If you choose textured plaster finish, be prepared for some headaches as explained in the reasons mentioned above. Smooth finishes give a more modern look, smooth is the trend - it will add value to your property as many home buyers look for smooth finishes. We get tons of calls and requests to smooth out ceilings and walls. The process is more complicated to skim a ceiling or to skim coat a wall. An expensive plaster bonding agent would need to be applied. This process is more laborious and takes more time to complete. It is more difficult to skim coat over existing plaster than applying plaster over new blueboard. So, let the swirl plaster ceiling be gone! :)
