How to prevent spalling and pitting in concrete with Saltguard

[@RichardFallstich]

At around 3:51 he says "when water and salt are mixed together, the freezing point is higher." This is incorrect. Adding salt to water reduces the freezing point of water. Not higher, but lower. Salt molecules block water molecules from packing together when temperature is lowered. It then prevents them from becoming ice. More water molecules leave the solid phase than the ones entering the solid phase. Freezing point depression occurs when the freezing point of the liquid is lowered by addition of a solute. On average, seawater in the world's oceans has a salinity of about 3.5 percent (35 g/L. Although the saltiness of ocean water varies, this lowers the freezing point of ocean water to about 28.8°F. You will note that 28.8F is LOWER than 32F; the freezing point of (mostly) pure water.

Does it stop chemicals from soaking into concrete ?

Do you mix it in or do you apply to existing g concrete?

[@ProsocoSince1939]

Saltguard is applied to existing concrete.

How is it applied and how long does it last?

[@ProsocoSince1939]

Saltguard is applied by a low pressure sprayer you are going to want to avoid puddles. A wet-on-wet application works best. The service life for Saltguard is about 7-10 years.

Would you recommend applying this every winter before snow storms hit or just once? Can you apply this to new or old concrete for maintenance? Asking because our company did a new concrete sidewalk 2 years ago and we are located in the northeast. our winters especially this year have caused spalling/ chips but no major cracks. Also very high traffic sidewalks for school means lots of salt every snow storm sometimes multiple times.

Hi, The service life of Saltguard is 5-10 years. If the area you are trying to protect is high traffic or see's a lot of salt you may want to check every 5 years or so. We recommend Saltguard be applied when the masonry surface temperatures are between 40-90°F (4-32°C). This can be applied to new or existing concrete. If new the concrete should be thoroughly cured before application. It does take at least 72 hours before Saltguard to gain its water-repellency properties. Here is a link to our product data sheet for more information. prosoco.com/Content/Documents/Product/PR_Saltguard_PDS_061220_C.pdf Thank you!

“Easier to freeze salty moisture” Huh?

[@ProsocoSince1939]

Ha! yeah, kind of clumsy wording. Should have said "Water that has salt content freezes at a higher temperature than water without salt content. And therefore water with salt content would freeze more often."

[@k12914]

@@ProsocoSince1939 Other way around. Salt lowers the freezing point of water. That's the whole reason why it is applied to roads and sidewalks. Salt makes freezing less likely.

@@ProsocoSince1939 huh? Test freshwater and salt water samples in freezing temperatures, if freshwater freezes before saltwater, let me know, because you're on a different planet than me. :-)
