What’s the Difference?
This week we are looking into PM’s Standard Solids (SS) Silicone Roof Coating. This roof coating is strong and versatile like PM’s HS silicone but there are some additional benefits to SS silicone that we wanted to point out:
- Cheaper price per bucket
- Easier on spray equipment
- Better sag on sloped surfaces
- Perfect for 2-coat substrates
Cheaper Price per Bucket
One of the top selling points of our SS silicone roof coating is the cost. This silicone is less expensive than our HS silicone which is enticing to many roofing contractors and building owners. When coating high-sloped roofs or roofs needing two-coats, this silicone is a perfect fit as it can keep the total project cost down. As we all know, keeping the bottom line low for clients is the best way to win work!
Easier on Spray Equipment
Another cost-saving benefit of SS silicone is it’s wear and tear on spray equipment. If you are a company that sprays silicone on a regular basis, you may want to look into our SS silicone as it won’t be as harsh on your equipment. Due to the lower solids content in the silicone, it can move through hoses and pumps easier, adding some life to your equipment. HS silicone is designed to work with silicone spray equipment as well and will not damage your equipment. SS silicone will simply be a bit gentler on the system in the long run.
Better Sag on Sloped Roofs
Better sag means that SS silicone will not run down a sloped surface as easy as HS silicone. This is particularly important when coating high-sloped roofs. If you are ever in a situation where the slope of the roof is substantial, you should consider PM SS silicone. By using this, you will get better, more uniform coverage on the roof as compared to a heavier, higher solids silicones.
Perfect for Two-Coat Substrates
There are a couple instances where two-coat applications are the preferred method. These are typically on high-sloped roofs and spray foam roofs. On these roofs, and any others where two-coats are preferred, SS silicone is typically the way to go. Because the cost is lower for PM SS silicone, if you’re going to be applying two coats, you may as well do it with the cheaper of the two silicones.
Before we close this blog series down, we wanted to mention one benefit that both HS and SS silicones share. When spray-applying, you can use PM HS and SS silicones simultaneously without having to clean the equipment. If you’re coating a roof with spray foam and EPDM, you can spray HS first and then spray SS (or vice versa) through the same rig without going through the rigmarole of disassembling and cleaning it first. This can save you significant time on complicated jobs like this.
We hope you enjoyed reading about the differences between HS and SS PM Silicone. As always, please reach out to your regional manager with any questions about specific details.
