ResinTech CRU Chemical-Resistant Urethane — Premium Protective Finish Coat

Two-Component, High-Solids Aliphatic Polyurethane Finish Coat — Maximum Chemical, Abrasion & UV Protection | Brand: ResinTech | 6 L kit

ResinTech CRU is a premium aliphatic polyurethane finish coat used as the final protective layer over compatible epoxy, polyaspartic, broadcast and traffic coating assemblies. It is for projects that need more than a standard topcoat: better long-term wear resistance, stronger chemical protection, excellent UV stability and a hard, cleanable finish. CRU is the thin durability layer of the ResinTech line — the final armour coat, not the build coat, membrane or fast-track coat. Confirm chemical exposure, surface preparation, system compatibility and cure schedule against the current ResinTech TDS, SDS and project specification before use.

Two critical application rules:
  1. Thin film only. Apply at 3–6 mils (recommended); never exceed 20 mils total. CRU is a thin finish coat and will fail in cure, appearance and adhesion above this thickness.
  2. Not recoatable once cured. CRU is the final coat. If any material must go over cured CRU, the surface must be mechanically abraded (sanded) first for a physical bond only — cured CRU will not chemically recoat.
Field Details
Brand ResinTech
Product Code CRU
Product Type Two-component, high-solids aliphatic polyurethane finish coat
Kit / Pack Size 6 L kit — Part A 4 L + Part B 2 L (1.6 US gal mixed), pre-proportioned 2:1 by volume
Mix Ratio Pre-proportioned A + B kit as supplied — do not alter the ratio
Colour / Finish Clear or field-pigmented; smooth, or slip-resistant when broadcast media is specified
System Role Premium protective finish — the final armour topcoat in ResinTech systems
Where CRU sits in the system: CRU is the final armour coat of the ResinTech system — prime and bond with CBE, build with TUE, fast-finish with HPP, and protect it all with CRU — the strongest, most chemical-, abrasion- and UV-resistant topcoat in the line. Apply thin (3–6 mils) over compatible cured coatings; it is the final, non-recoatable layer. Confirm the system specification against the current ResinTech documentation.

Best-Use Applications

Application Notes

Always confirm application requirements against the current TDS, SDS and project specification before use.

Surface Preparation

Apply only to clean, dry, sound substrates or compatible cured coatings. Remove dust, laitance, oil, grease, curing compounds, sealers, loose broadcast and bond breakers. Existing coatings must be sound, compatible and properly abraded — do not apply over glossy, soft, unknown or poorly bonded coatings. Mechanically prepare concrete to the profile required by the base system; for recoating cured resin, abrade uniformly to remove gloss. Vacuum thoroughly before coating. Moving joints must remain functional and be sealed separately with appropriate joint sealant. Confirm against the current TDS.

Mixing

Condition material to application temperature before use. Pre-mix each component separately; add compatible pigment to Part A where a pigmented finish is required. Combine the supplied Part A and Part B in the correct pre-proportioned ratio and mix mechanically for 2–3 minutes at low speed until uniform. Scrape sides and bottom of the pail and avoid whipping air into the coating. Do not thin with solvents. Apply promptly after mixing and maintain a wet edge. Confirm against the current TDS.

Application & Overcoating

Apply by high-quality roller, squeegee and backroll, brush for details, or spray where appropriate; maintain an even film. Apply at 3–6 mils (recommended) and do not exceed 20 mils total — excessive thickness causes cure failure, blush and adhesion loss. CRU is not recoatable after cure: sand / abrade the cured surface uniformly to achieve a mechanical bond before applying any subsequent material. For slip resistance, use specified silica sand, quartz, aluminum oxide or approved traction media. Apply clear coats thin and uniform over decorative systems, avoiding puddles that can alter gloss or cure. For pigmented coats, use consistent batching, backroll direction and film thickness; mock-ups are recommended for appearance-critical work. Protect fresh coating from rain, condensation, dust, foot traffic, tires and turning stress until sufficiently cured. Confirm against the current TDS.

Limitations
  • Do not exceed 20 mils total film thickness — CRU is a thin finish coat (3–6 mils recommended) and will fail in cure, appearance and adhesion above this limit.
  • Not recoatable once cured — any subsequent coat or repair requires mechanical abrasion (sanding) of the cured surface for a physical bond only.
  • CRU is a finish coat — not a primer, build coat or crack-bridging membrane.
  • Do not apply to wet, frozen, dusty, contaminated or condensing substrates.
  • Do not apply over unknown or incompatible coatings without adhesion testing and approval.
  • Slip resistance depends on aggregate type, broadcast rate, film thickness and maintenance — approve texture by mock-up.
  • Chemical resistance varies by concentration, temperature, exposure time and housekeeping — test severe exposures before use.

Does a good job, but too much philosophy.
Format: Kindle
I'm about halfway through this book. I have a condition that makes it hard to read. This book does a good job of teaching SQLite but spends too much time stressing the importance of comments and style. I agree, that these things are important, however, not to the audience of the book. The reader would have been better served by getting into the grit of SQL syntax and which keywords to use when versus ensuring that every query had a comment block with name, date, and description. Moreover, requiring every reader to download a prewritten database to work from and special utilities to follow along takes away from the learning experience. That said, you will learn the basics about SQLite, and by the end of the book be able to handle most problems you'll encounter when developing an application.

Great book!
The free promotional items the company gives you just for buying this product alone make it worth the five stars I have given it, and the product itself is amazing. I should start by noting that I received this product about 5 days ago and I am currently halfway done with it. This is not a book that teaches you the very basics of computer programming and assumes that you already have a basic grasp of the fundamentals such as arrays which you definitely should if you are even the slightest bit interested in learning SQL. The book begins by teaching you about what the program is, how it is becoming a valued skill in the world, and why it is a better programming language than others. It makes a language that most people consider highly advanced and more and more difficult the more you use it very easy to grasp in a way that could potentially change your entire career. I am not a computer science expert myself and have only a basic understanding of programming language, mostly java, but I was able to read this book and understand almost all of it without a problem. My computer science friends are even surprised by how much I was able to learn about this programming language that they consider impossible in such a short amount of time. I highly recommend this product if you have any interest at all in learning a new programming language or just giving yourself another skill because they make it very simple to learn. Disclosure: I received this product for free or on a promotional discount for my honest review and they are 100% my own opinions. However everyone has their own opinion on this product. I did not receive payment other than receiving the product at a discounted rate and I am not required to give a good review. I know how important my reviews are to people who are interested in buying this product, because everyone should be reading reviews before they purchase a product. What I include is what I actually think about the product and my opinion alone. My reviews accurately reflect my views on this product and any 5 star product I would recommend to both my friends and family as well as purchase at full price. This disclosure is in accordance with the Federal Trade Commission’s Guidelines on Testimony and Advertising. I provide honest reviews that describe the product it entirety both the positive and negatives (if there are any). If my review was helpful to you, would you please vote yes!

Great beginner book but should have covered layout
Format: Kindle
I've done HTML and made an attempt to learn CSS before. This book is a GREAT choice for beginners as well as myself. The examples are pretty easy to follow and made sense. Most of all this was THE book on CSS I was looking for. My previous attempt to learn CSS was overly complicated and convoluted and left me completely confused on CSS and barely able to get the job done. Perhaps it was because it was for the specific software I was using rather than just CSS. Regardless, after this book I feel confident with CSS now and was surprised how easy it actually is when properly explained. My only complaint on this book is that I think it should have covered page layout with parent DIVs and child DIVs or page layout in general. That's definitely the next thing to learn after reading this book. But I was able to easily find a video on page layout after reading the book and took it to the next level. This book prepared me for that and got me to a place where I was ready for that. Hopefully the next version of the book will include page layout techniques to give your website a more professional look. I'm giving it 5 stars because page layout and graphic design really probably are intermediate topics. So, for an HTML and CSS book, this really "hit the spot"!

Easy to follow for a beginner!
Format: Paperback, Format: Paperback
It’s easy to follow and understand, like putting a puzzle together following step by step instructions eventually feeling more and more confident. You will learn how to build a website starting with HTML. Love the exercises and snippets. If you never used VS code text editor, I suggest watching video on social media about VScode editor if you use this book. VS is a great code editor and it’s free. Pro tip- install live preview from extensions from your explorer pane, it saves time refreshing a browser to see your work and refreshes in real time as you build and style your pages. The book will go into detail about more technical terms as you move through the chapters. I am a student in Front End Web development and everything internet. This book does a good job identifying some of the technical terms of how browsers display HTML documents in a viewport leading up to responsive design. This book is beginner friendly. I don’t think you need any knowledge of HTML, or CSS to start with this book. You don’t need to be an IT technician either, just a simple understanding of how the internet works. You do need to have an interest in learning to code though because it can be a learning curve. Persistence, patience, and lots of practice will make you successful and that’s the payoff. Buy with confidence!

A Solid Book & Place To Start!
Format: Paperback
So far I'm enjoing this book and I do recommend it for beginners and novice programmers alike. It's a sold read and an extremely solid place to start. I knocked off a star because it also does tend to be a little longer than needed.
