Coating Solutions for Tar & Gravel
Loose gravel hides splits, blisters, and saturated felts. After spudding and pressure washing, soft T272 polyester conforms over the embedded gravel surface and the acrylic system locks it into a single monolithic membrane.

Acrylic steps
- Specified Acrylic Primer
- Acrylic Base Coat
- Polyester Fabric
- Acrylic Top Coat
Tar and gravel may use a silicone coating path or a reinforced acrylic hybrid with silicone top coats. Surface profile and remaining aggregate affect the final appearance and coverage.
Follow the current written specification for preparation, coverage, film thickness, and installation.
Preparation guidance for your installer
Common roof concerns
- Loose aggregate hiding splits
- Saturated felts below low areas
- Irregular texture that consumes coating
Field preparation
- Spud and remove every loose stone
- Pressure-wash and locate saturated areas
- Level repairs before embedding soft polyester
Release checkpoints
- Only firmly embedded aggregate remains
- T272 fabric is fully saturated without fishmouths
- Drains and ponding areas receive extra attention

Answers before the roof brief.
Use these answers for planning, then follow the current written specification for the project.
Can an existing Tar & Gravel roof be coated?+
A Tar & Gravel roof may qualify when the assembly is identified, sound, dry, repairable, properly prepared, and proven compatible through project-specific testing. Wet or unsound areas must be addressed before coating.
What preparation does Coating Solutions for Tar & Gravel require?+
Preparation depends on the exact substrate and condition. Inspection, moisture review, cleaning, drying, repairs, detail work, and representative adhesion testing come before the final primer and coating sequence.
How is the material quantity calculated?+
The estimator uses measured roof area, detail length, system family, planning term, and a waste or texture allowance. Actual ordering must follow current coverage rates, specified film build, surface profile, and field verification.
Which technical documents belong in the project file?+
Start with the system specification, then include the current product data, safety data, applicable detail drawings, approvals, warranty requirements, and any written project-specific instructions.
When should the technical team review the roof?+
Request a review whenever the substrate is uncertain, moisture or drainage is a concern, adhesion results vary, prior coatings are present, warranty coverage is planned, or field conditions differ from the published system.
