How it works
From Bare Exterior to a Finish That Lasts Decades
Exterior plasterwork done right requires proper preparation, the correct mix, and experienced application. Here is exactly how we approach every job.
Site Visit & Exterior Assessment
We visit your property and assess the exterior walls thoroughly — checking the existing substrate, identifying cracks, moisture ingress, failed plaster, or problem areas that need addressing before any new coat is applied.
Transparent Quote & Scope Agreement
We provide a detailed, itemized quote covering all labour, materials, and surface preparation work — no hidden costs. The full scope is agreed in writing before we begin, so you know exactly what is included and what it costs.
Surface Preparation & Plaster Application
We prepare the exterior surface correctly — removing loose or failed material, applying bonding agents where needed, and building up the plaster in the correct sequence of coats. Each coat is allowed to cure properly before the next is applied, ensuring maximum adhesion and durability against the elements.
Final Inspection & Weather Test
We inspect the completed exterior surface in full daylight — checking for even coverage, correct finish, and no weak or hollow spots. We clean up the site completely before handing over, and confirm that the plaster is fully cured and ready for any exterior paint or coating you plan to apply.
Common Questions
Exterior Plasterwork Questions — Answered
Here are the questions we hear most often about exterior plasterwork. If yours is not listed, just call or message us.
When applied correctly using the right materials and preparation, exterior plasterwork can last 20–30 years or more. The key factors are proper substrate preparation, correct mixing ratios, adequate curing time between coats, and the application of a good quality exterior paint or sealant afterward. OZ follows best practice on all of these — which is why our plasterwork performs long after cheaper alternatives fail.
Yes — when the right products are used. We specifically select frost-resistant, waterproof plaster systems designed for Canada's climate. These mixes are engineered to expand and contract with temperature changes without cracking, and to resist moisture penetration that causes freeze-thaw damage. We never use interior-grade products on exterior surfaces.
Not necessarily. Hairline cracks are often surface-level and can be repaired and blended without touching the rest of the wall. However, if the plaster is hollow behind the cracks, if moisture has penetrated, or if large sections are loose or failing, a full re-plaster is the only lasting solution. We assess the extent of the problem honestly on our site visit and give you a clear recommendation before any work begins.
A standard residential exterior typically takes 3–7 days depending on the size of the property, the number of coats required, and drying time between coats. Larger commercial buildings or properties with significant repair work take longer. We provide a realistic schedule in your quote and stick to it — keeping you informed at every stage.
No — and this is one of the most common mistakes homeowners make. Fresh exterior plaster needs to fully cure before painting, which typically takes 4–6 weeks depending on weather conditions. Painting too early traps moisture inside, causing paint failure and plaster damage. We will advise you on the exact wait time for your job and recommend the right exterior primer and paint system to protect the plaster for the long term.
