Hourly Rates
Project Costs
Indicative 2026 rates for Colombo and the suburbs, based on Snapwerks quotes and published Sri Lankan market data. Outstation districts usually run 10-20% lower on labour. Expect the top of each range during the Avurudu rush in March and April and at the start of the monsoon. Always get the scope and the price in writing before work starts.
Frequently Asked Questions
1. How much does plastering cost per square foot in Sri Lanka?
Internal wall plastering costs roughly Rs 150 to Rs 320 per square foot for labour, and external walls Rs 190 to Rs 400 because of access and weather exposure. Ceilings cost more, at Rs 220 to Rs 450, since the work is overhead. A skim and putty finish adds Rs 90 to Rs 200.
2. What does a plasterer charge per day?
A plasterer charges Rs 3,500 to Rs 5,500 per day in Colombo and the suburbs, with a helper at Rs 2,000 to Rs 2,500. Day rates suit patch repairs; measurable areas are cheaper and easier to compare when quoted per square foot.
3. Why is my plaster blowing or flaking?
Nearly always moisture. Rising damp from a missing damp-proof course, a leaking embedded pipe, or driving monsoon rain on an exposed wall will lift plaster from the block behind it. Fix the water source first; a patch repair at Rs 4,500 to Rs 25,000 will otherwise fail within a season.
4. How long should plaster cure before painting?
Allow at least two to three weeks for new plaster to dry properly in Sri Lankan conditions, and longer in the monsoon or in a shaded, poorly ventilated room. Painting too early traps moisture and causes the paint to peel, which is one of the most common repaint complaints.
5. What is plastering as a share of building a house?
Plastering and finishing account for roughly Rs 1,500 to Rs 2,500 per square foot of floor area within a full house build, against a 2026 total of Rs 5,500 to Rs 7,500 per square foot for a basic finish and Rs 8,000 to Rs 12,000 for a standard one.
