Plastering: scheduling around the drying

A plasterer controls the start of the work and almost nothing after it. The set and the dry run on their own clock.

Every trade behind them inherits that clock. Most site programmes still treat plaster as though it behaved like paint.

Three different waits, and only one of them is the set

• The set, which is chemical and fairly predictable.
• The dry, which depends on the weather, the ventilation and the thickness.
• The readiness for the next trade, which is later again and is what the builder actually needs.

A programme that allows for the set and calls the wall ready books the painter two days early. The painter discovers that on site.

Conditions change the dry more than the mix does

A closed house in winter dries slowly whatever goes on the wall. A cross breeze and a dehumidifier change the answer more than any product choice.

Ventilation is therefore a scheduling decision rather than a site preference. It belongs in the conversation with the builder.

Book the week so a slow dry costs nothing

A week holding three jobs that all need drying has one bad day and loses all three. A week alternating between setting and finishing absorbs it.

The pattern matters more than the order: something to start while something else dries, on every day of the week.

Tell the builder in days, not in adjectives

Saying a wall needs a while invites the builder to guess, and the guess is always shorter than the answer.

A number with its condition attached travels properly: ready Thursday with the windows open, Monday with them shut. A builder given both will usually open the windows.

Photograph the wall when leaving it

Damage to fresh plaster happens after the plasterer leaves, and the argument about it happens a week later.

A photograph at the end of the visit settles it in a minute. Our guide to site safety paperwork covers keeping those pictures where somebody can find them again.

Price a rushed dry rather than absorbing it

A builder who needs the wall tomorrow is asking for heaters, fans and a return visit. All three cost money.

A named rate for accelerated drying turns that into a decision the builder makes with their own budget. Without one it becomes a favour that gets expected.

Patch work and full rooms need different bookings

A patch takes twenty minutes and the same drying time as a wall. Batching patches into one visit wastes the drying; spreading them across a week wastes the travel.

A sensible pattern books patches around a larger job in the same suburb, so the travel is already paid for and the drying happens anyway.

The finish level belongs in the quote

A wall for a textured paint and a wall for a gloss in raking light need different levels of work. Customers rarely know those differ.

Naming the level in the quote prevents the most expensive conversation in the trade, which is a finished wall judged against a standard nobody agreed.

It also prices honestly. A higher finish takes more coats and more sanding, and a quote that ignores that loses on every job needing one.

A named level also protects the plasterer from a builder who changes their mind after painting starts. Both parties named the level, and a higher one becomes a variation with its own price.

What to change first

• The programme separates the set, the dry and the readiness
• Ventilation gets agreed with the builder rather than assumed
• Each week alternates setting work with finishing work
• Readiness gets quoted as a date with its condition attached
• A photograph records the wall as the plasterer left it
• Accelerated drying carries a named rate
