TotalBoat 6 Lb Density Expanding Foam Kit, 2 Part Closed Cell Polyurethane Liquid Foam for Boat Flotation, Casting, Carving, Sculpture, Reinforcement and Void Filling (2 Quart Kit)

Amazing product, I’ve been waiting 6 months to try this product.Yesterday, the weather finally allowed me to get some work done.LOVE IT!Expands evenly and fills like crazyMy boat will float!!

I use the foam to expand inside of the hollow area of a sculpture. Expanded fast expanded well and was as hard and durable as I hoped.

I'm putting a new floor in a 1986 glastron ski boat. The area in the picture is 6 feet long by 2 1/2 feet wide and 4 inches deep. It took the entire 2 gallons (1 gallon mixed) of 6 lb foam to cover the floor. When dry it's solid as a rock. You can walk on it with No compression or crushing. Only problem for me was I expected a greater volume from 1 gallon of mix. I expect that if it was a lower Lb like 3 or 4 it would expand more. Hope this helps you. Frank

This foam was not quite as dense as I needed, but I also didn’t know what density I needed. But it will work great for other uses.

Forms quickly and works great for adding support where needed. Make sure to know how much you will need before ordering to make your project come together faster

Others suggest the sparse instructions are a negative, but you’ve only got to READ and COMPREHEND the instructions given. Understanding how various 2 part mixes work is a plus.I used 1 pint each of A + B and employed a small mechanical paint stirrer with a variable speed drill to mix. It rapidly became homogenous and coffee colored. I could feel the heat building while I was pouring the final bit into the cavity I wanted to fill.I’d estimate that it produced approximately 2/3 cubic foot of foam.Temperature of cavity was 78° F. It seems obvious that the warm temp definitely contributed to rapid expansion and intimate volume.

Lo compré para mí embarcación y me leí todas las opciones, quise dejar aparte las opiniones negativas ya que nunca me han servido de mucho a la hora de comprar y nunca he tenido ningún problema con mi método de estudiar los productos que compro. La verdad me llegó realmente rápido ya que viene de EE.UU y yo estoy en Menorca, bueno total, ayer me llegó y hoy he decidido hacer una prueba, no quería opinar sin probarlo evidentemente, me he mirado todos los vídeos que he podido encontrar de total boat de gente que lo aplicaba me he leído todas las instrucciones e incluso la temperatura ambiente aquí en España es de 27 grados la que recomienda el fabricante para la mezcla, después de la pequeña prueba no creo que crezca 10 veces más de lo que añades ni mucho menos y la espuma como le des un golpe se rompe, luego me he decidido a hacer una prueba de inmersión y solo 5 segundos debajo del grifo an sido suficientes para beber toda el agua, parecía una esponja de ducha, espero que con la garantía me devuelvan almenos el dinero ya que he gastado 200€ en un kit de un galón, no lo recomiendo para nada sin duda aquí los comentarios negativos tienen toda la Razón.

The TotalBoat instructions say mix for 15 to 25 secs (depending on temperature), but how "intensely" you mix makes a bigly difference.I needed about a dozen 20-24 oz batches for my project. My yield was low until I got lucky and mixed it (always using a drill mixer) a bit longer / faster - when the two parts transitioned from a uniform creamy tan color to a significantly darker coffee color.The color change was kind of dramatic / instant and it seemed to be accompanied by an equally dramatic change in viscosity. Prior to this little discovery, I would mix it (what I thought was aggressively) for the requisite time, achieve a consistent (creamy tan) color and pour - always to be disappointed with the yield. I was mixing 24 oz in a half gallon container, and there were times, I was concerned it would sling over the top of the pail before "the change".I recommend that you do a greater number of smaller batches instead of one big pour if you can manage it. The expansion "seems" to be more reliable that way, and all you your eggs are not in one basket.I got the 2 gallon - 6lb / CuFt kit, and found that the finished product was robust / tough / solid and probably expanded to the advertised ~3 CuFt volume after I got the mixing thing sorted. The 6lb stuff is definitely harder and denser than any polyurethane foam I've used before. The cured foam can be tough to cut with a serrated knife.Obviously, you need the correct temperature (75 to 90F, yep the tech guy at TB said 80F is great, but up to 90F is ok), and the correct mixture (1:1 by volume, 1:1.09 by weight - because the activator is heavier).Here's why they got 3 stars:1. Come on Man! TotalBoat knows people are disappointed in yield, and I did everything by the book, only to wind up with - you got it - low yield! They should add a tiny note in their description to make sure purchasers know to whip it good - till it turns coffee colored and the viscosity changes. Heck, they could even make a video.2. First go around, TotalBoat mailed me only the Part B (see pic). Come on Man!3. Second round, TotalBoat mailed me a Part A that was leaking! There's an aluminum seal, but the cap was not tight (Drrr!).It's like they have a good product, but then just don't try.I tried to include a link to the technical data sheet for the 6lb foam, but AMZN would not allow that.Godspeed.
