Tremco Vulkem® 191 QD Primer

Quick-Dry, Single-Component Urethane Primer for Traffic Deck Systems | Brand: Tremco

Tremco Vulkem® 191 QD is a quick-drying, single-component urethane primer for use under Vulkem traffic deck and waterproofing membrane systems. Applied to properly prepared concrete and metal substrates, it is designed to improve adhesion of the Vulkem base coat and help reduce outgassing that can cause pinholes or adhesion issues in the membrane. Confirm suitability, primer requirements, coverage, and recoat windows against the current Tremco TDS, SDS, and system specification before use.

Professional system note: Vulkem 191 QD must be used as part of an approved Tremco traffic deck or waterproofing system. Do not apply the Vulkem base coat before the primer has fully dried to the specified tack-free state. Confirm primer requirements and recoat windows with the current Tremco system specification.

Product Description

Vulkem 191 QD is formulated for accelerated dry times compared to standard Vulkem primers, allowing the Vulkem base coat to be applied sooner and helping to reduce overall system installation time; confirm dry times against the current TDS as they vary with temperature and humidity. Its single-component formulation requires no mixing. The QD (Quick Dry) designation indicates an accelerated dry time compared to standard Vulkem primers; confirm performance against the TDS for your specific site conditions.

The primer is designed to penetrate and seal the concrete surface, improving the bonding interface between the substrate and the Vulkem urethane membrane. On metal substrates, it provides a compatible bonding interface for the Vulkem system. Proper substrate preparation and primer application are critical to the long-term performance of the complete traffic deck system.

Key Characteristics

  • Quick-dry formulation — accelerated tack-free time compared to standard primers; confirm dry times against the TDS as they vary with temperature and humidity.
  • Single-component — no mixing required; apply directly from the container.
  • Designed to improve adhesion — formulated to improve the bond between concrete or metal substrate and the Vulkem urethane membrane; final adhesion depends on substrate condition, preparation, and application method.
  • Designed to reduce outgassing — formulated to help reduce outgassing and pinholing in the applied membrane; confirm requirements against the TDS.
  • System-compatible — designed for use with Vulkem 350NF, 360NF, and other approved Tremco traffic deck and waterproofing systems; confirm system compatibility against the current Tremco specification.
  • Concrete and metal substrates — confirm substrate preparation requirements against the TDS before application.

Typical Applications

  • Primer for Vulkem 350NF / 360NF traffic deck systems on concrete
  • Primer for Vulkem waterproofing membrane systems on concrete and metal
  • Parkade and parking structure deck primer coat
  • Podium and pedestrian deck substrate preparation
  • Metal substrate priming for Vulkem system compatibility

Surface Preparation

Concrete must be mechanically profiled (shot-blasted or ground), clean, dry, and free of laitance, oil, grease, curing compounds, and incompatible coatings. Metal must be clean, dry, and free of rust, mill scale, and oil. Conduct moisture testing on concrete before application. Refer to the current Tremco system specification for substrate-specific preparation requirements and acceptable moisture levels.

Application Instructions

  1. Substrate preparation: Prepare the substrate as described above. Confirm moisture levels are within acceptable limits per the TDS.
  2. Application: Apply Vulkem 191 QD by roller or brush at the coverage rate specified in the TDS. Ensure uniform, thin coverage across the entire substrate area.
  3. Dry time: Allow the primer to dry to the specified tack-free state before applying the Vulkem base coat. Do not apply the base coat before the primer is fully dry.
  4. Recoat window: Apply the Vulkem base coat within the recoat window specified in the TDS. Do not exceed the maximum recoat time without re-priming.

Limitations

  • Must be used as part of an approved Tremco system — not a standalone waterproofing product.
  • Do not apply to damp, contaminated, or unsound substrates.
  • Do not apply below minimum temperature or when condensation or rain is expected before cure; confirm temperature requirements against the TDS.
  • Do not apply the base coat before the primer has reached the specified tack-free state.
  • Do not exceed the maximum recoat window without re-priming.

Storage & Shelf Life

Store in original, unopened containers in a cool, dry, ventilated area away from direct sunlight, heat, and moisture. Confirm shelf life and storage conditions against the product label and current SDS.

Health & Safety

Read the current Safety Data Sheet (SDS) before use. Contains isocyanate and solvent components — wear gloves, eye protection, and ensure adequate ventilation. Refer to the SDS for full hazard classification and first-aid measures.

Great frother and well built
Color: Black, Size: Rechargeable
I don’t usually write reviews, but since I’ve been helped by so many reviews from others, I wanted to share my thoughts on the InstaWhisk Milk Frother. This is a great frother. It really whips cream into a tasty, rich froth. My wife and I have tried cheaper battery-operated frothers in the past, and while they worked fine at first, they didn’t last very long. The InstaWhisk feels well built and works great. Pro tip: The frother may be a little too powerful at normal speed, so you might need to lightly “feather” the power button to keep the liquid from overflowing the cup. Once you get used to it, it works really well.

Great frother/stirrer especially for the price.
Color: Black, Size: Rechargeable
Best one available. Have used cheap ones from the store that work pretty good, but batteries are a pain. This is rechargeable and it has a push button that allows you to start it right away without having to turn it on to start it kind of like a power drill. If you start to press it it goes slow the harder you press the faster it goes. The different attachments are great. We use it for both coffee frothing as well as mixing up electrolyte drinks with water with the included mixing attachment. Crazy powerful and easy to use.

Strong motor. Works great
Color: Black, Size: Rechargeable
I really like this frother. The fact that it’s variable speed, rechargeable, and can spin at a high rate are all great features. I use it to blend collagen powder and cream into my coffee every morning. Also sometimes use it to Blend drinks. Strong motor. Like that the whisks are removable for cleaning and that it comes with different ones.

Works well, long use on single charge, high torque - be careful when starting
Color: Black, Size: Rechargeable
Not the most inexpensive powered whisker bur I've used other Typhor products and found them reliable for the task designed. I fell they don't cheap out on the rechargeable battery so I don't fell they will catch fire, as we are hearing about from other cheaper rechargeable items. I liked 2 things about this model the speed control is by a pressure single switch which I can control, not just pick speed 1,2,3. The swappable tips allow for different uses. I don't drink coffee but use the item to whisk eggs for an omelets and it has the torque to mix them without effort. In Fact need to only use half power else it will splatter out of my mixing vessel.

Still The Best Frother Ever!
Color: Black
I love how it is easy to use, how it holds a charge, and how much power it has. I've only charged it once since I got it & I've been using it on a daily basis!!! Though it isn't a long time, I'm happy with it so far! I definitely will recommend it to anyone looking for a great frother. If you are looking for one, look no further! You won't be disappointed! I've read some comments where they found it to be too strong that their drink spilled everywhere. But for me I have not had any incident of spilling over. I have used it both for my coffee and my matcha tea and it worked great without any spilling over. You just have to start with the lowest power and ensure that you have a large enough container to have a room for your frothing. My sister tried to use it recently during her visit to make us matcha tea. However, she experienced spillage all over the cup, because she had used a small cup. Otherwise, she liked it very much and said she will get one when her battery operated one stops working... Another thing I like about the product was the customer service that I had received. When I got my first order which came quickly, it wasn't working after having charged it over 24 hours. It was not turning on at all. I returned it and ordered a replacement which I received within a day or two. This time after charging it for the recommended amount of time, I was a bit skeptical when I turned it on. However, I was pleasantly surprised that it worked like it was supposed to and it has been working ever since having charged it only once so far. I may come back and give an update depending on how it does after 6 months of use, so keep in tune... I don't know if there is a way to write a new entry as a follow up to the old entry, so I'm going to add my follow up comment over here. May 23, 2025 - I love my frother more than I can say in words. It's functionality has not changed a bit from the time I have purchased it. It charge lasts several weeks to few months before I charge it again and the power is still the same. Recently I decided to buy another one for my office use. I like the white color and so tried it but that one wouldn't even turn on. And then I got a gray one to have a different color. That one was much weaker than the black one I own. Then I replaced it with another gray one within few days. I tried it and it was exactly the same as the one I already replaced. So then I decided to go with a black one again hoping that it would be the same as the one I have. The black one did much better than the gray ones in the strength or power of the frother. However, it is weaker than the one I already have been using since last August. While I am not very happy with the quality being inconsistent in all of the ones I have tried including the recent pictures of the black one, I have decided to keep the black one because it is relatively better than the gray ones I tried. What I don't understand is why there is inconsistency in the quality of the same product by the same maker. I am beginning to wonder if the black one I purchased in Augusta last year was anomaly of a quality and a good way. Maybe I lucked out on my older black frother, but I'm unsure if quality is going to get better if I were to order another one. I have a sister who is a pro in making coffee drinks and she was the reason I had ordered this frother to begin with. She uses a battery operated one at this time and I have been thinking about getting her one like mine. While I am still skeptical, I am going to give it a shot and order her one sometime soon. If it doesn't work, I guess we will return it back. But one thing that I am grateful is that I have been able to return every one of those that I have tried recently with no issues. I hope that I don't have to return my most recent purchase in black. I was not even able to review the new purchase because of the item being the same color which is crazy.
