LP SmartSide siding is a composite material made from wood fibres and synthetic resins
LP SmartSide siding is created through a combination of wood fibres, resins, glues, and waxes. These materials are combined using heat and pressure to produce a highly durable board. The wood fibres are treated to resist termites and fungal decay, and the siding is further protected by a resin-saturated overlay. This overlay provides an additional layer of protection against moisture intrusion and UV damage, creating a smooth, paint-ready surface.
The manufacturing process of LP SmartSide siding ensures that it is a long-lasting and high-performance product. It is also more economical than natural wood siding, as it is easier to install and maintain. LP SmartSide siding comes in a variety of styles, including lap siding, shingle, panels with vertical grooves, and trim. It can be painted or stained to match any home's design, providing endless customisation options.
When painting LP SmartSide siding, it is important to choose the right type of paint and application method. While the siding comes pre-primed, any exposed edges created by cutting a plank must be primed before painting. Acrylic latex coatings designed for wood composites are highly recommended. It is best to paint on a dry, partly cloudy day with temperatures between 40 and 85 degrees Fahrenheit to ensure proper drying of the paint.
LP SmartSide siding offers superior durability, versatility, and customisation options, making it a popular choice for homeowners and builders alike. With its long lifespan, low maintenance requirements, and eco-friendly profile, LP SmartSide siding is a smart investment for those seeking an attractive and durable exterior solution.

The ideal temperature for painting is between 40 and 85 degrees Fahrenheit
LP SmartSide siding is a composite material made from wood fibres and synthetic resins. It is designed to look like wood and can be painted to suit any taste. Painting LP siding is a great way to add a personal touch to your home's exterior.
When painting LP siding, it is important to consider the temperature. The ideal temperature for painting is between 40 and 85 degrees Fahrenheit. This is because if it is too cold, the paint will dry slowly and may drip. On the other hand, if it is too hot and sunny, the paint will dry too quickly and may crack. Therefore, it is best to choose a dry, partly cloudy day with no rain in the forecast and temperatures within the recommended range.
In addition to temperature, other weather conditions can also affect the painting process. It is best to avoid painting in hot, humid weather, near-freezing temperatures, or on gusty, windy days. Cloud cover or an overcast sky is ideal, as it provides some protection from the sun while allowing the paint to dry properly.
Proper preparation is also key to ensuring a successful paint job. The siding should be clean, dry, and free of damage before painting. If you are painting brand-new siding, little preparation is required as it comes pre-primed. However, if you are repainting old siding, it is important to remove any dirt and mould to ensure the new paint will adhere properly. A pressure washer is an effective way to clean the siding, and a tip with a 15- or 25-degree spray pattern should be used to avoid damaging the siding.
When it comes to the type of paint, acrylic latex coatings designed for wood composites are highly recommended. LP SmartSide siding comes in three formats: lap, shingle, and panels with vertical grooves. The recommended application method is spraying, as the siding's format does not lend itself well to painting by roller.

Painting in cold weather will cause the paint to dry slowly and may drip
Painting in cold weather can cause issues with the paint's drying time and appearance. LP SmartSide siding is a composite material made from wood fibres and synthetic resins, designed to look like wood. It can be painted to suit a homeowner's taste and to protect the siding substrate. However, when painting in cold weather, the paint may dry too slowly, leading to possible dripping.
LP SmartSide siding is a popular choice for those seeking the look of traditional wood siding with easier maintenance. To ensure a satisfactory paint job, it is important to consider the weather conditions. Painting in cold weather can cause the paint to dry too slowly, which may result in dripping. Therefore, it is recommended to choose a dry day with temperatures between 40 and 85 degrees Fahrenheit for optimal painting conditions.
The ideal conditions for painting LP siding are low humidity, a cloudy sky, and moderate temperatures. Painting in cold weather can cause the paint to dry too slowly, which can lead to dripping and an uneven finish. It is important to avoid painting near freezing temperatures to prevent this issue.
Additionally, proper preparation is key to a successful paint job. The siding should be clean, dry, and free of damage before painting. If the siding is new, little preparation is needed, but if it is old, removing dirt and mould is essential to ensure the paint adheres well. A pressure washer is an effective tool for this step.
Overall, while LP SmartSide siding offers the opportunity for customisation and protection, it is important to be mindful of the weather conditions when painting. Painting in cold weather can cause slow drying times, leading to possible dripping. By choosing the right temperature range and ensuring proper preparation, a smooth and professional paint finish can be achieved.

LP SmartSide siding comes pre-primed, but exposed cut edges must be primed
LP SmartSide siding is a popular choice for homeowners who want the look of traditional wood siding with easy maintenance. LP siding products are treated to resist termites and fungal decay. They are also designed to stand up to hail and other impacts. LP SmartSide siding comes pre-primed, with the front and edge surfaces of the siding and trim primed at the factory. This saves time and protects the product.
However, when LP SmartSide products are cut on the job site, the wood substrate can be exposed. It is important to prime and paint these exposed cut edges to protect the siding substrate. LP's application instructions specify that all exposed edges must be primed and painted with approved paint. Failing to do so may void the product warranty.
The back side of LP SmartSide siding is better left unpainted. Back priming is not intended for LP SmartSide products, although it may be useful for some other types of solid wood siding, trim, and composite sidings.
When selecting paint for LP SmartSide siding, acrylic latex coatings designed for wood composites are recommended. Priming and painting LP SmartSide siding can help to transform the look of a home and increase its curb appeal. It is important to follow the proper procedures to ensure the siding is protected and the desired aesthetic is achieved.

Use a pressure washer to remove dirt and mould from old siding
LP SmartSide siding is a composite material made from wood fibres and synthetic resins. It is designed to look like wood but with added benefits, such as being more impact-resistant and longer-lasting. LP SmartSide siding can be painted to suit the homeowner's taste and to make it look brand new.
Before painting LP siding, it is important to ensure the surface is clean and free of dirt and mould. A pressure washer is the fastest and easiest way to remove dirt and mould from old siding. A pressure washer can be used to blast away mould and mildew, and extension wands can be used to avoid the need for a ladder. It is important to select the correct detergent for this task, and to avoid using bleach, which can damage the machine. The detergent should be applied from the bottom up and allowed to sit for 5 to 10 minutes before being rinsed with a low-pressure spray pattern, also from the bottom up.
The ideal pressure for washing siding is between 2,000 and 2,500 psi, with a tip that has a 15- or 25-degree spray pattern. The tip should be kept at least 6 inches away from the siding to avoid causing damage, and it should be pointed straight at the siding or slightly downward to prevent water from getting behind. It is important to work slowly and carefully to effectively clean the siding without causing any damage.
For smaller structures, such as sheds, a paintbrush may be preferred for cleaning and painting. A brush with synthetic bristles and a telescoping handle can be useful for reaching high sections and cleaning nooks and crannies. A garden hose with a sprayer attachment can also be used to remove loose dirt and spiderwebs, and for rinsing the cleaning solution.
