How to Waterproof a Planter Box

Planter boxes are a wonderful way to add additional plants, flowers, and trees to your home or business. Just like any other outdoor surface, they need additional waterproofing to extend their life and avoid expensive water damage.
When it comes to waterproofing a planter box, however, there are more considerations than many might realize. Read on to learn more about the benefits of planter box waterproofing and how you can waterproof the right way.
Why Waterproof Your Planter Box?
In most cases, planter boxes receive the greatest amount of water exposure of any outdoor structure. Since planter boxes must withstand both rain and regular watering, waterproofing is extra essential to protect your planter boxes from water damage.
While protection from water damage is the primary benefit of planter box waterproofing, there are a few additional benefits that may help improve the health of your plants and even reduce your water bill.
Prevent Water Damage
Whether your planter box is made from wood, concrete, or any other material, waterproofing is crucial for avoiding water damage. Planter boxes require more waterproofing than almost any other outdoor structure, since they must also withstand regular plant watering in addition to rain and other harsh weather conditions.
Preventing water damage in a planter box can also help prevent water damage to surrounding structures. With proper drainage and waterproofing, water won’t have a chance to infiltrate nooks and crannies that could eventually spread rot, rust, and mildew.
Save Water
Applying a waterproof coating to the inside surface of your planter boxes can help save water in the long run. While saving water might sound counterintuitive when it comes to waterproofing, planter boxes without waterproof coatings are prone to absorbing or leaking water while leaving plants dehydrated.
With a waterproof coating, your planter box will retain smaller amounts of water for longer without damaging its materials or structure. As a result, you’ll be able to maintain your plants with much less water—something that’s especially important in drier climates.
Healthier Plants
The water-saving benefits of planter box waterproofing also extend to the plants themselves. Where a planter box without waterproofing will leak or absorb water without providing enough for the plants, waterproof boxes save water and help promote healthy, hydrated plants.
As we’ll see later, most waterproof planter boxes still have drainage installed, allowing property owners and gardeners to strike the balance between proper hydration and sufficient drainage for even the most finicky plants.
Extend Planter Life
From avoiding water damage to maintaining healthier plants, waterproofing ultimately extends the life of the planter box itself. With both inside and outside surfaces thoroughly protected from rot, rust, mold, and mildew, waterproofing can significantly extend the life of planter boxes of any material.
Steps to Waterproofing a Planter Box
While planter box waterproofing follows a similar procedure to waterproofing decks, patios, and other outdoor surfaces, it often requires additional preparation to allow for proper soil drainage.
Before waterproofing can even begin, however, your planter box will need a little prep work!
Clean the Planter Box
No matter what you’re waterproofing, a clean surface is essential to ensure that waterproof coatings and meshes can adhere properly. Depending on the material and condition of the planter box, you may need to perform extensive surface preparation before waterproofing.
Of course, preparing a new planter box is easiest. With a surface free from dirt and deterioration, new planter boxes only require a quick sweep or soak to remove excess particles or debris. By contrast, older boxes require complete soil removal and an extensive cleaning of both interior and exterior surfaces.
For concrete and metal boxes, cleaning may require through pressure washing and other laborious surface preparations. Thankfully, most waterproofing professionals will do this step for you.
Install Drainage Points
Planter boxes need adequate drainage to prevent over-watering and water entrapment. If your planter box doesn’t already have a drainage system, then you’ll need to install one before applying a waterproof coating.
Drainage points also require extra preparation for waterproofing. Since drainage adds holes and corners to otherwise flat surfaces, they’ll likely need the same waterproof mesh strips as corners before a waterproof coating can be applied. Once this work is finished, however, waterproofing can proceed normally.
Apply Waterproof Coating
With a clean surface and plenty of drainage points, waterproofing can finally begin! As mentioned previously, drainage points and corners often require extra strips of waterproof mesh before waterproofing can begin. These mesh strips help ensure that hard-to-reach areas, such as tight corners and crevices, will remain waterproof if coatings don’t fully penetrate.
Just like a deck or other outdoor surface, waterproofing is usually applied as one or more liquid coats. Once the coats are dried and set, the waterproofing should last several years before reapplication is necessary. Planter box interiors may last even longer with proper drainage and the protection from sun, wind, and rain provided by the soil.

How to Waterproof a Balcony

Waterproofing your balcony is one of the best ways to keep it strong and safe for years to come. Since balconies are constantly exposed to rain and harsh weather conditions, balconies without thorough waterproofing often begin to deteriorate within only a few years.
Thankfully, there are a few things you can do to waterproof and secure your balcony. While there are a few DIY options available, a professional can help in some unexpected ways—many of which are also unexpectedly affordable.
About Balcony Waterproofing
Deck waterproofing is the process of applying a waterproof coating or sealant to your deck’s surface. While the exact coating used may vary depending on the surface material, the underlying principle is the same: creating a barrier between water and your deck.
Deck Dangers: The Importance of Waterproofing
Waterproofing is highly recommended for all outdoor surfaces, especially decks and balconies. Since these surfaces receive constant exposure to the elements, having a protective coating is crucial for protecting the structure against damage and deterioration.
Water and weather aren’t the only deck dangers, however: Foot traffic, furniture, and other forms of wear and tear can also affect your deck or balcony’s integrity. Thankfully, waterproof coatings also help guard against this extra wear and tear by enhancing the overall durability of your outdoor surfaces.
For many property owners, however, waterproofing seems more like an expensive “add on” than a valuable investment—until their balconies start falling apart, that is!
Do I Need Balcony Waterproofing?
Every balcony in every climate can benefit from waterproofing in some way. The benefits are especially clear for balconies in wet and humid climates with high amounts of regular rainfall. Here, waterproofing not only protects surfaces during rainstorms but helps prevent rot and rust forming from ambient humidity and trapped water.
What about dry climates? Don’t be fooled: Balconies and decks in dry climates are especially susceptible to water damage since long periods of dryness can make wood and other materials soak up moisture like a sponge. As a result, when rain or water finally does come, the resulting water damage can be especially bad.
In addition to protecting the balcony itself, waterproofing also helps protect the surrounding structure from residual water damage while also maintaining and preserving your balcony’s original finish. With all these benefits, many property owners are quick to start waterproofing themselves.
The Balcony Waterproofing Process
There’s more to balcony waterproofing than just brushing on a finish coat! Like painting and other surface treatments, waterproofing requires a careful combination of surface preparation, application, and finishing to form a proper seal.
Surface Preparation
Most waterproof coatings require a clean and well-prepared surface to adhere properly. While preparation methods can vary, depending on the surface material, all surfaces should be thoroughly cleaned and free of dirt, debris, and dust before coating.
While concrete or masonry surfaces require little preparation beyond cleaning, wood and metal—two very common balcony materials—require extra preparation. Wood, for example, should be thoroughly finished and sanded before applying waterproofing. Metal surfaces should also be completely free of rust; otherwise, the rust will continue to develop regardless of the waterproof coating.
In addition to cleaning the surface, you may also need to fill in cracks with a polyurethane sealant or apply a primer. Whether you’ll need to use a primer depends on your balcony’s surface material and the type of waterproof coating you’ve chosen.
As you might be able to imagine, most of the work involved with waterproofing is in the preparation! Just like with painting and finishing, however, preparation will determine the quality and integrity of the waterproof coating.
Waterproofing Application
With the surface thoroughly prepared, the waterproofing can finally begin!
Depending on your balcony’s shape and construction, waterproofing will require laying strips of PVC/mesh waterproofing membrane along all corners and joints. These strips are first secured using a liquid waterproof coating as an adhesive and laying them on while the coating is still wet. Once the strips are set, a second coat of waterproofing is applied over the strips to seal them completely.
It’s also worth applying the same process to the edges and drains of your balcony where possible. Edges and drains receive the greatest amounts of water flow and should also be sealed with PVC/mesh strips before applying the final coat.
Finally, with mesh applied to corners and other hard-to-reach or “high flow” areas, a final coat of liquid waterproof coating is applied using a roller brush or spray applicator. Once the coat dries, the balcony will be completely waterproof—assuming preparation and application were done correctly, of course!
Long-Term Care
Though waterproof balconies are relatively low-maintenance, the coating can start to wear down after years of wear and tear. As a result, your balcony will likely require regular re-coatings over the course of its life. How often you’ll need to re-coat your balcony will depend on your climate and your balcony’s exposure to rain and regular use.
DIY or Professional?
While it’s definitely possible to waterproof your balcony by yourself, it’s an incredibly laborious process that requires careful planning and preparation.
Since a waterproofing job can easily go awry without the right application, it’s usually best to call a professional to ensure a thorough job and ultimately save time and money. Waterproofing professionals will also be able to identify key areas on your balcony that may need more waterproofing than others.

7 Ways You Should Invest in the Exterior of Your Home

Investing in the exterior of your home can have many benefits. It can improve aesthetics and provide space to relax or enjoy recreational activities. There may also be opportunities to increase curb appeal and property value. If you’re wondering how to update the exterior of your home, here are a few design ideas to consider.
1. A New Garage Door
The garage door is a prominent feature, so an update can have profound results. Paneled, carriage style, and other types of doors can add intricate details. Even if your garage door has some service life left, you can go beyond repainting to replace it and take advantage of modernized features like Wi-Fi control and monitoring.
If debating whether to pay for a new garage door, consider that, according to Remodeling Magazine’s 2019 Cost vs. Value Report, nearly 98% of the cost can be recouped when selling your home.1
2. Add Exterior Lighting
There are many energy-efficient options, so adding more lighting won’t have a significant impact on your utility bill. Exterior lighting can highlight your home’s architecture, trees, or landscaping elements. It can also provide visibility along a yard path, around a garage, or by the front door. Outside lighting can add ambience, but don’t forget it can also deter would-be burglars and thieves; therefore, it’s a great safety and security measure for the front of the house.
3. Update the Roof
Roof replacement is an expense most homeowners want to avoid, but a worn roof may need replacement after 20 years. If there are missing shingles or water damage, chances are other underlying problems are present.
Replacement is pretty high on the list as far as ROI, but, if an inspector doesn’t suggest replacement, redoing the shingles can spruce up the look of your home. Modern asphalt shingles come in many different shapes, colors, and patterns. Shingles aren’t cheap, but you can recoup a healthy percentage of the cost when selling a home.
4. Build a Deck
An attached or detached deck adds outdoor living space. A wood deck can add a fair amount to your home’s selling price as well. The opportunities it provides for entertaining guests, grilling, relaxing, sunbathing, or spending time alone or with family is invaluable. Much goes into a deck, from wood and other flooring materials to finishes, railings, and stairs; a renovation contractor can help design, plan, and build the perfect deck for your home.
5. Add Planters to Your Landscaping
Attractive landscaping can include stone walkways, fountains, and planters. A planter is easier to maintain than a garden and can be selected in a color and texture that complements your home’s exterior design. You can decorate a planter for every season and have your pick of greenery, flowers, and even vegetables such as decorative kale, lettuce, onions, and peppers.
6. Create a Patio
A backyard patio creates a flexible outdoor space where you can play ball on an adjacent lawn or install an outdoor kitchen or fire pit. Various landscape elements can be added, or you can cover your patio so it’s useful even on rainy days. Patios are ideal for recreation, relaxing, and entertaining.
7. Refresh Your Landscape
A full landscape overhaul provides numerous opportunities. You can add a walkway, stone or concrete pavers, flower beds, stone planters, colorful flowers, or stylish borders. It’s also a chance to remove weeds, replace mulch, and mow the lawn. If you have the budget for it, dark flagstone can update the porch and stairs and increase property value.

How to Avoid a Slip and Fall Lawsuit on Your Property
If you regularly welcome people to properties that you own, whether as a landlord or a business owner who operates a retail space, you might be worried about slip and fall liability. After all, if someone is injured in a fall on your property and it is determined that you have been negligent in some way, the financial ramifications could be significant. Fortunately, there are several options for reducing your exposure, here, including using building waterproofing surfaces. Let’s take a closer look at this important topic.
Start with Stairs
As you take an overview of your property to determine where you can make safety improvements, stairs are a good place to start. There are a few points you can check regarding your stairs, including the presence of a solid, secure handrail. Having a handrail available is important for safe use of the stairs, but it will only be helpful if it is secured firmly in place.
Also, check to make sure the rise between each stair is even. When walking up or down the stairs, people naturally expect each step to be the same as the last. If there are awkward changes in how much the stairs rise between each tread, those spots could become a problem.
Avoid Slippery Spots
Something as simple as a slippery floor can create the environment for a slip and fall accident to occur. Consistently cleaning up your spaces is an important part of avoiding slippery spots, but you can also have some areas treated by commercial waterproofing contractors to create better traction. Good waterproofing companies in Los Angeles, CA will be able to create walking surfaces that make it easier for users to maintain their footing.
Present a Tidy Space
You don’t want to force your customers or visitors to navigate around messy areas that may cause them to stumble and be injured. For instance, in a retail store, leaving loose boxes piled up in areas that are meant for use by customers would be setting the stage for an accident to occur. Be sure to keep up with organizational tasks during business hours to not only keep everyone safe but also offer a better experience for your customers.
Getting Help
If you still aren’t sure exactly what you should do around your property to limit your slip and fall risks, consider asking your insurance company for help. Some insurance companies will be happy to provide free resources to help you make improvements since they would prefer to avoid any claims coming down the line. This can be a great way to have a professional take a direct look at your property, so any concerns can be highlighted and remedied.
