Question Is there a good sealant for concrete?

Now that I've done my repair job on my concrete step (with mortar), what is a good sealant to cover the entire step so the elements don't get in and wear away at it over time?

Yes, protection from elements. What specific brands and products should I look at for sealing concrete at a reasonable price (small quantities of sealant)?

Although Thompson's is a decent sealer, I don't believe it's in the same call as the others mentioned. Regardless of which you use, repeated application will be needed almost yearly.

sil siloxane's advantage is that annual resealing isn't necessary,,, being an industrial material, its also more expensive but has great shelf life,,, we have some stuff 3yrs old which still performs well

TWS does a good job of sealing most substrates it's applied over BUT it generally has a very short life when exposed to the elements.

IF i thought thompson's were better, we'd use it,,, have never seen it spec'd on any fed/state/municipal work yet & i did that work for 30yrs,,, true we do lose some jobs today due to higher mtl costs but that's rare,,, 1/2 of the 1's we do lose have come back shortly,,, i think the other 1/2's too embarrassed to call us,,, i don't think any of our competitors have the breadth of mtl knowledge/methods/equip so that gives us a leg up

Stadry, let's look at who you're talking to.

What you say is absolutely true but does the average DIY want to spend the money on a professional grade material that will also sooner or later need to be redone at some point in time.

Thompson's' and others similar to it are meant for the consumer level. Do a cost comparison. A 5 gal bucket of PS110 Siloxane Water Repellent WB-10 Penetrating Sealer goes for $150.00. Thompson's is $65.00 for a 5 gal bucket. And Thompson's does do a decent job for homeowner use.

XSPLR,

Very interesting. Not sure if it's cost effective after buying the linseed and mineral spirits and then the time to mix it. But I learned something new today.

What type of foundation? above or below grade?

IMO TWS has too short of a life to be a viable option on the exterior.
