Filling Cracks In Exterior Walls: What Are My Options?

filling-cracks-in-external-walls.jpg

Cracks in walls are never a welcome sight, whether they’re on the inside of your home or on the outside. The good news is that not all cracks are a threat to your property, sometimes they just appear over time.

For those cracks that are more of an aesthetic issue, like small hairline cracks, repairing the problem is not too difficult, and whilst not always necessary, can help to restore the look of the exterior of your property. 

Here are four of the main options that you have when filling cracks in exterior walls:

Option One: Latex Caulk

Latex caulk, and particularly caulk that is silicon-based, is the perfect product to fill in cracks that have appeared in plaster. A latex caulk can be used to fill in most small hairline plaster cracks and some slightly larger cracks in plaster

Applying latex caulk is normally quite easy as you’ll find that most latex caulk products designed for filling in cracks are available in a tube which can easily be attached to a caulking gun. 

Once you have removed any debris from the crack and made sure that it’s clean, filling in the crack is just a case of applying the caulk via the gun and smoothing the product at the end to match the texture of your plaster. When the caulk is dry, you can paint over it to conceal the repair.

A filler compound is an effective product to use for larger cracks in plaster that can’t easily be filled with a small line of caulk or layers of concrete epoxy. You can mix your own filler compound or purchase ready-mixed compound form most DIY stores

Option Two: Concrete Epoxy

Concrete epoxy is a popular product used for filling in cracks on exterior walls that are made from concrete. Depending on the size of the crack, the concrete epoxy will either need to be injected into the crack or worked in with a brush. 

Before the concrete epoxy is applied, the crack will need to be completely clean and free of debris. Then the epoxy can be applied in thin layers until the crack has been properly filled, before being textured and painted.

Option Three: Filler Compound

A filler compound is an effective product to use for larger cracks in plaster that can’t easily be filled with a small line of caulk or layers of concrete epoxy. You can mix your own filler compound or purchase ready-mixed compound form most DIY stores.

The process involved in using a filler compound is very similar to using caulk, in that the crack needs to be cleaned and dry before the filler can be used. The filler can be used to completely fill the crack, bringing the surface flush with the surrounding masonry.

Option Four: Call in the Professionals

The final option is the most advised if you’re not 100% sure about filling in cracks in exterior walls, the cracks are large, or you’re concerned that they’re a sign of something much worse that simple aesthetic damage.

When you call in the experts, you’ll be able to have a professional inspection of your exterior walls undertaken and get tailored advice on the best methods to solve the crack problems.

Home Logic: Crack Repair and Coatings You Can Count On

Cracks in exterior walls are an eye-sore but they also could be causing damage to the interior of your home, or to your insulation, by allowing water to seep into the brickwork. 

Once water enters the brickwork and infects your cavity wall insulation, your home will start to leak energy, causing your rooms to become colder and your energy bills to get higher. 

At Home Logic, we offer the perfect solution to cracked walls and the ongoing protection of masonry from extreme temperatures and adverse weather. This solution comes in the form of our protective wall coatings. 

After a thorough inspection of your exterior walls, and after all the cracks have been repaired and the wall has been treated, our protective coating can be applied to the surface. 

This hydrophobic coating deflects grime and water, causing rain to bead up on the surface of the wall and roll down it, rather than seep into it. With the wall coating in place, grime will be a thing of the past and water absorption will be reduced by 95% - helping to lower the thermal conductivity of your home!

If you’re concerned by cracks in your walls then getting them repaired and your walls protected should be a top priority, both for the aesthetic appeal of your home and for essential protection from damp.
