Ease of Application

The GE Advanced Silicone Caulk is a 100% silicone glazing compound designed for sealing windows and doors. Being fully waterproof and weatherproof, it provides strong protection against water damage and can handle harsh outdoor conditions well. Its drying time is quick—rain-ready in about 30 minutes and fully cured in 24 hours—which is helpful if you need a fast seal. The product is very flexible, offering about 40% more flexibility than many standard sealants, which means it can move with window frames without cracking, a key feature for long-lasting seals.

It also boasts strong adhesion, sticking well to a wide range of materials such as wood, metal, glass, and masonry. This flexibility and adhesion contribute to its durability, resisting cracking, shrinking, and mold or mildew buildup for up to 10 years. However, one downside is that silicone sealants like this are generally not paintable, so if you need a painted finish, this might not be the best choice. Also, the maximum gap it can fill is around 0.38 inches, which is fine for typical window sealing but not for larger gaps.

In terms of application, the liquid form in a squeeze tube makes it easy enough for DIY projects, but some users might find it a bit tricky to smooth without practice. This product suits homeowners and DIYers looking for a reliable, waterproof, and durable window glazing compound, especially where flexibility and weather resistance are priorities.

Sarco Type M Glazing Putty (Gallon)

Rating
7.9
Type of Glazing Compound
Drying Time
Ease of Application

Most important from
218 reviews

Type of Glazing Compound
The linseed oil base ensures the putty remains flexible and durable, resisting brittleness and cracking over time.
Drying Time
While it requires patience to fully skin over before painting, its quick drying compared to other oil-based putties helps speed up restoration projects.
Ease of Application
It spreads easily and is reasonably simple to work with, especially when using the right tools like a sharp putty knife.
Durability
Properly applied and painted, this compound can last for decades, even on windows exposed to significant weather.
Flexibility
The linseed oil base ensures the putty remains flexible and durable, resisting brittleness and cracking over time.
Paintability
Once fully cured, it can be painted with either oil or acrylic paints, providing versatile finishing options.

Sarco Type M Glazing Putty is an oil-based glazing compound designed mainly for interior window repair, especially when windows are removed and restored in a workshop. It dries relatively quickly, developing a skin in 2 to 7 days and fully curing in about 5 days, which is faster than some other putties. This quicker drying time can help speed up projects. The putty is elastic and water-resistant, making it durable enough to handle slight movements or changes in the wood without cracking. Its low viscosity means it spreads smoothly and is fairly easy to apply, though working with oil-based products may require some care compared to water-based options.

It forms a strong bond to wood surfaces, which supports long-lasting repairs. Once the putty skins over, it can be painted with either oil or acrylic paint, offering good flexibility for finishing. One gallon covers a generous 336 linear feet, suitable for larger jobs. Because it's oil-based, it needs an oil-based primer if you choose to prime before glazing, and it may feel less user-friendly for beginners compared to simpler water-based compounds. Also, it is intended for interior use only and might not be the best choice for exterior glazing.

For those seeking a reliable, quick-drying putty for indoor wood window repairs that can be painted over easily, Sarco Type M is a solid pick, though its oil-based nature and shop use recommendation should be considered.

Buying Guide for the Best Window Glazing Compound

Choosing the right window glazing compound is essential for ensuring that your windows are properly sealed, insulated, and protected from the elements. The right compound can help improve energy efficiency, reduce noise, and extend the life of your windows. When selecting a glazing compound, consider the type of windows you have, the climate you live in, and your specific needs for durability and ease of application.
Type of Glazing CompoundThere are several types of glazing compounds available, including oil-based, latex-based, and silicone-based compounds. Oil-based compounds are traditional and provide a durable seal but take longer to dry and can be more challenging to work with. Latex-based compounds are easier to apply and clean up with water, but may not be as durable in extreme weather conditions. Silicone-based compounds offer excellent flexibility and weather resistance, making them ideal for areas with significant temperature fluctuations. Choose the type that best matches your window material and the environmental conditions in your area.
Drying TimeDrying time refers to how long it takes for the glazing compound to set and become firm. This is important because it affects how quickly you can complete your window project and how soon the window can be exposed to the elements. Compounds with shorter drying times are convenient for quick projects, while those with longer drying times may provide a stronger, more durable seal. Consider your project timeline and weather conditions when selecting a compound with an appropriate drying time.
Ease of ApplicationEase of application is crucial, especially for DIY projects. Some compounds are more pliable and easier to spread, while others may require more skill and effort to apply smoothly. If you are new to glazing windows, look for a compound that is known for being user-friendly and forgiving. This will help ensure a neat and effective seal without frustration.
DurabilityDurability refers to how well the glazing compound can withstand weather conditions, temperature changes, and general wear and tear over time. A more durable compound will last longer and provide better protection for your windows. If you live in an area with harsh weather conditions, such as extreme heat, cold, or humidity, opt for a compound that is specifically designed to handle those challenges. This will help maintain the integrity of your windows and reduce the need for frequent re-glazing.
FlexibilityFlexibility is the compound's ability to expand and contract with the window materials as temperatures change. This is important because it helps prevent cracking and ensures a long-lasting seal. Silicone-based compounds are known for their excellent flexibility, making them a good choice for areas with significant temperature variations. If your windows are subject to frequent temperature changes, prioritize a compound with high flexibility to maintain a secure seal.
PaintabilityPaintability refers to whether the glazing compound can be painted over once it has dried. This is important for achieving a uniform appearance and protecting the compound from UV damage. Some compounds are designed to be paintable, while others are not. If you plan to paint your windows or match the glazing to the window frame color, choose a compound that can be painted. This will help ensure a cohesive look and added protection.
