Sealants & Primers

Choosing the perfect primer or sealant prior to applying tape is vitally important in ensuring the successful and constant airtightness of your passive home. Our primers can be used on porous surfaces and are ideal for applications on bare wood and masonry. Use these primers and sealants internally or externally for superior results.
Airtight Sealant
When using a sealant or primer, you should always ensure that that surface has been cleaned and dried thoroughly prior to application. Allow to dry completely before you apply any tape or membrane and take the time initially to prepare the surface. By investing time at the preparation stage, you can be assured of long-term adherence of the tape or membrane, which will in turn provide you with a secure and log-lasting airtight seal.

When you choose Passive House Systems for your primer and sealant requirements you can benefit in the following ways:

Easily create an airtight seal on any surface.
Avoid folding and unnecessary cutting, especially in any corners that require special attention.
By firstly preparing the surface with a sealant or primer, you can cut down considerably on tape or membrane application time.
Durability is enhanced through the use of high quality products.
Elasticity and adherence are vastly improved through prior surface preparation.
