In-Depth Comparisons Between Tamoseal And ThoroSeal

Now it’s time to get into more details. You can make the right choice when you know about them in detail.

So, here are some key differences between the two sealers:

  • Product Type
Tamoseal Waterproofing

Tamoseal is a cement-based and polymer-modified material mainly designed for waterproofing masonry and concrete substrates.

Apart from that, Tamoseal waterproofing can effectively seal a range of other substrates.

It will become an excellent sealer for vertical and light-duty horizontal surfaces if you mix this waterproofing formula with FLEX-CON or AKKRO-7T acrylic admixture.

On the other hand, ThoroSeal is a cement-based waterproof coating formula.

You can use this breathable micro-porous and seamless coating formula for filling, sealing, and waterproofing various substrates.

You can use it on various substrates, including pre-cast & cast-in-place concrete, masonry, brick, stucco, unglazed terra cotta, and porous stone. It’s suitable for the exterior and interior of new construction or renovation projects.

Besides, it’s an ideal alternative to mechanical finishing on substrates.

  • Features & Benefits

Tamoseal is a multipurpose formula. You can do both waterproofing and decoration using this cement-based sealer.

After applying, it’ll become an integral part of your substrates, and this breathable formula will create a tenacious bond over your surface which will be durable.

It’s available in two standard colors, Gray and White. Apart from that, some other colors are available to order in large quantities, including Oyster, Alpine, Pearl, etc. The sealer is slightly flexible and can seal static cracks.

On the contrary, you can use ThoroSeal for interior and exterior substrates. This breathable formula allows interior moisture to escape without affecting the coating.

Besides waterproofing, it can hide blemishes and minor surface defects on concretes.

It can protect exterior walls and other surfaces from standing water and wind-driven rainwater; you can also use it as an alternative to rubbing, concrete, or mechanical finish.

It’s available in two colors, White and Standard Gray. However, you cannot use it on painted surfaces.

  • Application Areas
ThoroSeal Waterproofing

Tamoseal can be applied on various substrates. But this formula is mainly designed for concrete and masonry.

That’s why areas made of these two materials will be the best place to apply Tamoseal.

You can apply it to waterproof concrete and block foundations, water tanks, reservoirs, interior or exterior walls, balconies, etc.

In contrast to Tamoseal, ThoroSeal works on more substrates. You can use this waterproofing formula in various interior and exterior places, including basement walls, containment walls, water cisterns, bridges, tunnels, roadways, below-grade interior & exterior, balconies, water tanks, and about every part of your home.

  • Coverage      

Under normal waterproofing conditions, a 50 lb. bag of Tamoseal can cover up to 225 square feet at the first coating. And for the finishing coating can cover up to 450 square feet per 50 lb. bag.

However, the amount will vary based on the texture and porosity of the substrates.

Similarly, ThoroSeal will also cover 225 square feet per 50 lb. bag in the first coating and 450 square feet in the second coating.

  • Cure Time

Tamoseal will take 12 to 24 hours to cure the first coating, and then you can apply the second coating. It’ll take at least 7 days to fully cure.

On the other hand, you can apply the second coat of ThoroSeal after 24 hours of the first one. But for a block or masonry wall, you should wait at least 5-7 days before the second coating. It will take 7-10 days to become fully cured.

  • Price

You will have to spend around $34 for 50 lbs. of Tamoseal. You might be wondering where to buy Tamoseal from. You’ll find them in any home improvement store and many online stores.
