Suggested Specification
The provided specifications are a guide to be edited to suit your project.
To specify any of the formliners by Scott System, please include the following language in your architectural specifications:
“Exposed architectural concrete surface treatment shall be obtained with Scott System HIPS or ABS form liner No. ________________ as manufactured by Scott System 109 General Fellows Road, Greenwich, NY, 12834, phone 518-383-0500. No substitutions will be allowed without prior written approval from the project architect or engineer.”
Texture numbers and short form specifications for each texture can be found on the plastic texture pages.
The long form specification that can be edited for your project can be downloaded here or on our resource page with additional information.
Application – Precast, tilt-up, or cast-in-place
Requirements for Re-use – We can supply cost-effective, single-use plastic liners or premium, multi-use elastomeric formliners specific to your application.
Rate-of-Pour – The typical liner’s strength is five feet per hour. We can recommend higher strength materials if your application requires this.
Design and Specifications
Finished Texture – Detailed finishes are successfully accomplished with a flexible, high grade formliner material.
Design Depth – High relief designs can be reproduced successfully and cost-effectively.
Design Shape – Geometric designs can be reproduced using HIPS, ABS, PE or PPE liners. Undercut designs will be successfully replicated using a highly flexible liner material such as urethane.
Design Specifications – Formliners are often specifically designed to meet your particular job requirements.
Budget Specifications
Project Budget –We will work to fit your budget and timelines!
Labor Budget – Our consultants can help avoid unnecessary job site labor costs such as trimming, material backing or sacking/patching.
Attachment to Formwork
Formliners can be used in precast, tilt-up or cast-in-place applications. Single-use HIPS is most frequently used for tilt-up applications and can be installed using Tek drywall screws or pneumatic staplers. Spacing should be approximately 6″ to 12″ on center around the perimeter and 18″ to 24″ through the center. Double sided tape, “Formica Top” adhesive, heavy duct tape or silicone caulk are all the common ways to attach formliners. Make sure all surfaces are clean, dry and free of dust and debris. Formliner PE & PPE liners for precast use are attached from the back with 3/8″ bolts when optional T-nuts are installed. Some deeper formliner patterns require back-up strips and are noted on the patters details shown in catalog. For details see section regarding back-up strips in our application guide.
Form Placement
It is important that forms for architectural concrete be aligned and in common planes. A “stack up” of manufacturing tolerances can result in forms being in different planes, even when properly aligned. This creates a noticeable “step” in the finished surface, particularly with shallow formliner patterns.
Rustication
Reveals or rustications are recommended at butted joints so it will allow the features of the liner to appear continuous. All butted joints should be taped and/or caulked to reduce grout leakage.
Form Release
Formliners should be sprayed with high end form release before each use and within the same day that concrete is placed. Apply with low flow, wide angle, flat spray nozzle and wipe with a cloth to insure a complete even coat to the entire formliner surface.
