Steps
Review the project's crack-control requirements and substrate movement potential to determine if added tensile/impact resistance is warranted
Consider fiber-reinforced base coats for high-impact areas, larger uninterrupted panels, or where enhanced crack resistance is specified
Confirm the fiber type and dosage match the manufacturer's data sheet for the specific base-coat product, since fiber reinforcement is largely a proprietary formulation matter rather than a single ASTM value
Verify the fiber-reinforced product is still compatible with the lath/furring and finish coat system specified for the job
Document the selection in the submittal so inspectors and the owner know a reinforced product was used instead of standard base coat
Known gotchas
Fiber reinforcement improves impact and crack resistance but does not eliminate the need for correctly spaced control joints
Fiber content and performance claims are manufacturer-specific; don't assume two 'fiber-reinforced' products from different manufacturers perform identically
