Silicone Primer for Porous Surfaces - Primer for silicone sealant - DL Chemicals

Primer for silicone sealant

• Promotes adhesion of the silicone sealant to the substrate
• The treated surface can be subjected to prolonged humid influences without risk of saponification.
• Primer for silicone sealant for porous and alkaline materials. Promotes adhesion of the silicone sealant to the substrate.

Applications:

• Fixing dusty and absorbent surfaces.
• For porous and alkaline materials.
• Suitable for professional use only.

Instructions for use:

1. Preparation :
   • The surfaces must be solid, dry and free from dust and grease.
   • If necessary, degrease with Parasilico Cleaner , MEK, alcohol or ethanol.
2. Laid :
   • Apply the primer to the surface with a brush.
   • In the case of highly absorbent surfaces, it may be necessary to apply the primer in several coats.
   • Once the primer is dry, apply the silicone sealant. Apply the silicone sealant within 16 hours at the latest. If this time has passed, a new coat of primer must be applied.
3. Consumption :
   • Max. 5 m²/litre

Packaging:

• 250 ml spray can
• 1L bomb

FAQ - Frequently Asked Questions

1. What is the purpose of Silicone Primer Porous Surfaces?
   It is used to improve the adhesion of silicone sealants on porous and difficult surfaces, in order to ensure a more durable and resistant seal.
2. Is it mandatory to use a primary primer?
   No, but it is highly recommended when the substrate is very absorbent or friable (cellular concrete, bricks, mortar), or when the adhesion of a standard silicone is insufficient.
3. Which silicone should be used after this primer?
   It is compatible with most of DL Chemicals' neutral, acetic and sanitary silicones.
4. How long should you wait before applying silicone?
   Drying time is generally 10 to 15 minutes. The surface must be dry to the touch before applying the silicone.
5. Can it be used on natural stones?
   Yes, but it is advisable to use a neutral silicone if the stone is sensitive to acids (marble, bluestone, travertine, etc.). A preliminary test is recommended.
6. Does the primer remain visible after drying?
   No, it becomes transparent and does not change the appearance of the surface.
7. Can it be used outdoors?
   Yes, it is perfectly suited for outdoor work, including in areas exposed to rain or frost.
8. How much should be applied?
   A very thin coat is sufficient. Too much primer can lead to poor adhesion.
9. What is the shelf life of the product?
   Generally 12 months in its closed packaging, at room temperature, away from a heat source.
10. Is it compatible with non-porous surfaces?
    No, on glass, aluminum, stainless steel or plastics, a primer offers no benefit. Using a suitable silicone is sufficient.
