If you own a home or commercial building in Winnipeg, you have likely heard elastomeric paint mentioned when talking about stucco, masonry, or concrete walls. It often comes up when there are cracks, moisture concerns, or long term durability questions. Naturally, that leads to a bigger question. What exactly is elastomeric paint, and is it actually the right solution for your building?
Elastomeric paint can be an excellent product in the right situation. It can also be the wrong choice if it is used without understanding the surface, the climate, and the long term tradeoffs. This guide explains what elastomeric paint is, how it performs in Winnipeg conditions, where it works best, and where other paint systems may be a better option.
Elastomeric paint is a high build exterior coating designed primarily for masonry surfaces like stucco, concrete block, poured concrete, and certain cement based finishes. Unlike standard exterior paint, elastomeric paint cures into a thick, flexible membrane.
That flexibility is the key difference. Elastomeric paint can stretch and move with the surface underneath it. This allows it to bridge small hairline cracks and resist water penetration more effectively than conventional paints.
In climates like Winnipeg, where buildings experience constant freeze and thaw cycles, that flexibility can be a major advantage when used correctly.
Winnipeg weather is demanding on exterior surfaces. Long winters, temperature swings, snow, ice, and moisture all take a toll on masonry walls over time.
Elastomeric paint is often chosen in Manitoba because it helps manage two common problems.
First, it reduces moisture intrusion. When applied properly, elastomeric paint creates a waterproof barrier that limits how much water can enter porous masonry.
Second, it helps accommodate movement. As temperatures rise and fall, masonry expands and contracts. Elastomeric paint can flex with that movement rather than cracking immediately.
That said, elastomeric paint is not a cure all. Climate alone does not make it the right choice. Surface condition, preparation, and long term maintenance expectations matter just as much.
Elastomeric paint is best suited for specific surfaces and conditions.
It performs well on older stucco that has developed fine cracking but is still structurally sound. It is also commonly used on concrete block walls where moisture intrusion has been an ongoing concern.
In commercial settings, elastomeric paint is often used on exterior masonry walls that are exposed to wind driven rain or snow buildup. In residential settings, it is frequently considered for homes with stucco exteriors that have experienced repeated paint failure.
In these situations, elastomeric paint can extend the life of the surface and reduce the frequency of repainting when applied properly.
Despite its benefits, elastomeric paint is not always the best option.
If a surface is already in good condition with no cracking or moisture issues, a high quality acrylic exterior paint may perform just as well with fewer drawbacks. Elastomeric paint is thicker and heavier, which means it is not ideal for every wall.
Brick is another example. Brick needs to breathe. In many cases, applying elastomeric paint to brick can trap moisture rather than solve a problem, especially if the brick is in good condition.
Elastomeric paint also requires careful surface preparation. If the surface is dirty, damp, or poorly repaired, the coating can fail prematurely. In those cases, choosing elastomeric paint can actually shorten the lifespan of the paint system rather than extend it.
When elastomeric paint is used in the right situation, it offers clear advantages.
These benefits are why elastomeric paint is often recommended for problem surfaces rather than cosmetic upgrades.
Elastomeric paint also comes with tradeoffs that homeowners should understand.
Because of these factors, elastomeric paint should be chosen intentionally, not automatically.

No coating performs well without proper preparation, and elastomeric paint is especially unforgiving.
Surfaces must be thoroughly cleaned, repaired, and fully dry before application. Cracks need to be addressed correctly before coating, not simply covered.
Moisture testing is critical. Applying elastomeric paint over damp masonry can trap moisture and lead to peeling or bubbling later.
This is where professional experience matters most. Knowing when a surface is suitable for elastomeric paint is just as important as knowing how to apply it.
A common question we hear in Winnipeg is whether elastomeric paint is better than acrylic paint.
The answer depends on the surface and the problem you are trying to solve.
Elastomeric paint is designed for flexibility and waterproofing. Acrylic paint is designed for breathability, color retention, and easier maintenance.
On stable surfaces without cracking, acrylic paint often offers better long term value. On surfaces with ongoing movement or moisture challenges, elastomeric paint can provide protection that acrylic paint cannot.
If you are unsure which system is appropriate, this is a good time to contact us and get guidance based on your specific building.
One of the most common mistakes is using elastomeric paint where it is not needed. Thicker does not always mean better.
Another mistake is applying it too thin. Elastomeric paint must be applied at the correct thickness to perform as intended.
Using elastomeric paint as a shortcut instead of addressing underlying surface issues is another frequent problem. The coating can hide issues temporarily but will not fix structural or moisture problems on its own.
Elastomeric paint makes sense when the goal is protection, not just appearance.
It is often the right choice for older stucco homes with minor cracking, commercial masonry buildings exposed to harsh weather, and surfaces that have experienced repeated paint failure due to moisture.
In these cases, elastomeric paint can help stabilize the surface and reduce future maintenance when applied by experienced painters who understand local conditions.
Choosing elastomeric paint should be a deliberate decision based on surface condition, climate exposure, and long term expectations.
It is a powerful tool when used correctly and a costly mistake when used incorrectly. Understanding both sides is the key to protecting your investment.
If you are considering elastomeric paint for your Winnipeg home or building, getting professional input early can save time and money later. When you are ready, contact us to discuss whether elastomeric paint is the right solution for your property.
What is elastomeric paint used for most often?
Elastomeric paint is most commonly used on stucco, concrete block, and masonry surfaces where flexibility and moisture resistance are needed.
Is elastomeric paint waterproof?
Yes, elastomeric paint provides excellent waterproofing when applied correctly, while still allowing some vapor to escape.
Can elastomeric paint be applied in cold climates like Winnipeg?
Elastomeric paint can be used in Winnipeg, but only within proper temperature ranges and with careful planning around weather conditions.
Does elastomeric paint last longer than regular paint?
Elastomeric paint can last longer on problem surfaces, but on stable surfaces a premium acrylic paint may perform just as well or better.
Is elastomeric paint worth the cost?
Elastomeric paint is worth the cost when it addresses specific issues like cracking or moisture. It is not always the best choice for every surface.
Should I hire a professional for elastomeric paint?
Yes. Elastomeric paint requires experience in preparation, application thickness, and surface assessment to perform correctly.

Elastomeric paint is not about upgrading for the sake of upgrading. It is about choosing the right system for the realities of your building and Winnipeg’s climate.
When applied in the right situations, elastomeric paint can protect masonry surfaces and extend their lifespan. When applied in the wrong situations, it can create new problems instead of solving old ones.
