Rethink Concrete Roof Sequencing - Build Sooner with SlopeShield Plus SA
SlopeShield Plus SA gives contractors the flexibility they need with today's demanding schedules and labor-challenged market.
Benefits:
- Apply as early as day-6 after a concrete pour or directly to damp concrete during reroofing
- Prevents weather-related rewetting enabling early dry-in
- Allows interior trades to safely begin BEFORE completing 28-35 day cure cycle
- Eliminates curing calendar resets avoiding costly setbacks
- Streamlines sequencing, protects the structure, keeps project moving
- Saves time, labor, and expensive project setbacks
Green, Fresh Pour Structural Concrete
Install SlopeShield Plus SA over green concrete a minimum of 5 days after pour. Ensure the surface is dry to the touch and meets all the required preparation requirements published in the installation instructions.

| Structural concrete roof preparation | Minimum 5-day cure time, apply SlopeShield Plus SA on day 6 or thereafter | Apply SlopeShield Plus SA to partially cured concrete, interior trades can begin |
Lightweight Insulating Concrete
SlopeShield Plus SA can be applied to lightweight insulating concrete. Substrate preparation includes priming the surface with sodium silicate approximately two days after the pour to lock in free lime and stabilize the surface chemistry.

Advantages of SlopeShield Plus SA Over Concrete
 |
|
|
Applying SlopeShield Plus SA on day-6 of the cure process:
|
Upon full cure, 28 to 35 days, SlopeShield Plus SA creates a walkable surface with excellent traction and supports construction equipment |
Reroof: Damp Concrete
During reroofing, damp concrete is often uncovered, causing delays while it dries. Applying SlopeShield Plus SA eliminates rewetting—even after rain—reducing schedule uncertainty and maintaining interior operations.

Concurrent drying and protection maintains project momentum |
Cure Times and Installation Guidance
SlopeShield Plus SA does not accelerate the natural curing process of concrete; proper curing is still essential for substrate integrity and performance. While SlopeShield Plus SA protects the concrete from external moisture and allows internal vapor to escape, VaproShield recommends allowing 28 to 35 days of curing from the pour date before installing the final roofing system. This guideline aligns with industry standards to ensure optimal results.
