Aldo Products is pleased to announce the newest addition to our product line.  ALDOSEAL 399 is a high solid, low VOC Silicone sealant designed for sealing roof penetrations, curbs, seams, flashings, and any other roof top areas susceptible to possible water infiltration. 

It is the sealant of choice for any roof system previously coated with a silicone elastomeric coating and can be applied rain or shine – or even underwater in emergency situations as a waterproof silicone sealant.

This means no stopping business for a full roof repair when you can restore it through this waterproof silicone sealant. It also means your work in restoring the roof will not be delayed by bad weather. If this sealant can be applied underwater, a little rain certainly won’t impair its effectiveness.

Of course, this only increases the advantages of a roof restoration compared to a roof replacement.

Mil for mil, ALDOSEAL 399 provides greater waterproofing protection for roofs than similar silicone sealants because of its powerful resistance to moisture penetration and its ability to adhere to a variety of roofing substrates.  

Once applied, this flashing grade sealant provides a durable, seamless and flexible system that resists lateral movement shear while allowing for normal expansion and contraction. The flexibility of this waterproof silicone sealant allows it to withstand any type of movement the roof system might experience over time. This means no fixing cracks in the sealant spots in the future; once it’s on, it stays on and stays waterproof.

The ALDOSEAL 399 waterproof sealant can also be used to help seal seams in gutter boxes that may have opened up or cracked due to movement in the system.

Available in 1, 2 and 5-gallon pails ALDOSEAL 399 is ideal for repair and restoration projects in conjunction with our coating grade silicone product line. 

Research and product development is a critical initiative for our team as we continue to expand our business. The addition of ALDOSEAL 399 is a direct reflection of our team working to improve our product line, addressing the many roof maintenance needs of our customers.
