Applications & Uses
- Applications
- Compatible Substrates & Surfaces
- Primary Uses
- Architectural restoration.
- Seals and fills interior and exterior masonry, stucco, concrete and previously painted surfaces
- Above-grade waterproofing and damp-proofing.
- Air-flow management (e.g. in nuclear power facilities)
- Plywood and particle board primer/sealer.
- Seals dry wall and sheet rock
- Primes and upgrades amny friable thermal insulation materials.
- Fumigation containment in tobacco storage warehouses.
- Dust control: Seals joints and seams on conveyors, dust collectors, elevators and other material-handling equipment
- Why Use L&L Primer/Sealer?
- Promotes adhesion on hard-to-stick-to materials.
- Seals porous surfaces, requiring less finish coatings.
- Easy to apply and cleans up with soap and water.
- Reinforceable with L&L Polyester mat, Polyester mesh and Dynel cloth.
- It's Elastomeric: Capable of stretching in excess of 12 times its original size and then returning.
- Application Equipment
Brush: Best results will be achieved using brushes with hog or other animal bristles. Quality nylon-bristle brushes may also be used.
Roller: Pressure fed or hand roller with 1" to 1½" nap cover.
Airless Spray Pump: Graco Bulldog 3:1 No. 221-061 fed by Graco Monarch 5:1 transfer pump No. 206-393
Fluid Hose: 3/8" or ½" ID with ¼" ID whip-end section
- Recommended Substrate Condition
All surfaces to be coated must be clean, dry and free of dirt, oil, grease, mildew, rust, wax, chalking or peeling coating and any foreign matter which could prevent proper adhesion. Never apply to surfaces which pond water.

Technical Details & Test Data
- Viscosity
L&L 163 Primer/Sealer is manufactured in two viscosities:
- "Light" brush, roller & airless spray grade
- "Standard" brush, roller & airless spray grade
When choosing viscosity range, consider factors such as surface profile and porosity, required film thickness and application methods.
Storage & Handling
- Handling and Storage
L&L 163 Primer/Sealer requires no mixing or thinning. Cleans up with soap and water when wet. Xylene required to remove dried material. Protect from freezing. Never apply at temperatures below +40°F. or when freezing temperatures are likely to occur before Primer/Sealer cures. Discontinue application three hours before sunset. Do not apply when rain is likely to occur. Shelf-life: 18 months when stored indoors at +40°F. to +100°F. Keep container sealed when not in use. Read and understand Material Safety Data Sheets before using product.
