Specifier FAQ

Where are the current SDS and product data sheets?

On this page. Each product card lists the Safety Data Sheet and Product Data Sheet first, with the revision next to each link, and the All documents table shows every file in one place.

What format are the guide specifications in?

Each guide specification follows the CSI three-part section format (Part 1 General, Part 2 Products, Part 3 Execution) and is available as an editable Word file and a PDF. Text in [Specifier: …] brackets marks choices for the design professional; delete those notes before issue.

Can you match our spec section or the products named in it?

Yes. Email the section to info@promasonsupply.com and we will tell you which of our products fit it and which items we don't sell.

Which mortar fits an older building?

The guide specs say the mortar should be softer and more vapor-open than the masonry units it joins. Type N is for hard, modern units (built after about 1950). Type O is for 1920–1950 masonry or softer units. PHL 3.5 is for pre-1920 or soft historic masonry laid in lime mortar. PHL 2.0 is for very soft, fragile or heavily weathered units and for sheltered or interior work. Use PHL 5.0 only where the units are hard and durable enough and exposure is severe. When in doubt, select the softer mortar and build a test panel. Mortar selection for structural work is the design professional's decision.

What sand do the specs call for?

The mortar guide specs call for clean, sharp, well-graded masonry sand, free of clay, silt, salts and organic matter, matched to the existing sand in color and texture. The PHL guide specs reference ASTM C144, and the Lime-Pro guide spec uses ASTM C144-type clean bagged masonry or plaster sand. The concentrates are mixed on site with local sand, so coverage is for the mixed material.

How do we estimate quantities?

Use the coverage tables in each Product Data Sheet and our material calculators. Email us if you need help with a takeoff.

How do we get samples?

Color Skim and Microcement come in 2-inch sample color chips: see the Color Chip Sampler and Microcement color chips. The mortars and Lime-Pro come in a 1-quart sample and small-project size, and Masonry Stain comes in sample jars. View chips in person before you choose a color. For mortar and plaster, build and approve a test panel or mock-up on the actual substrate before ordering in quantity.

Is there a manufacturer warranty?

No manufacturer warranty is offered. Products are sold subject to the manufacturer's standard disclosure, which is reproduced in each guide specification and submittal sheet.

Do you publish test reports, VOC or LEED documentation?

Not currently. The only standards statements are the ones shown on each product card, with the qualifiers in the documents. Email info@promasonsupply.com with questions.

How are substitutions handled?

Follow the substitution requirements in the project's Division 01. Each guide spec leaves a place for them.

How do orders ship?

Orders ship by UPS from Olathe, Kansas, and typically leave within 1–2 business days. Live UPS rates are shown at checkout.
