How to stretch vinyl on bulky shapes - Car Upholstery 

I used this technique to shape the center hollow part of the console: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Eb94VA5jhpE.html

There is an explanation on the video description:....."The secret is the application of 'polyurethane glue' on the reverse side. Two coats of glue if the shape is too bulky."....... I applied the technique on a console hollow center panel: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Eb94VA5jhpE.html

I have stretched the one way stretch automotive vinyl to almost its maximum stretching. It is only a demonstration on how vinyl could be stretched. Common sense makes us stop when we feel the material is tensioned enough and prone to tearing. Regularly, in car upholstery it is not necessary stretch the material too much. I applied the technique on the hollow center panel of a car console. Just a little bit that helped me to do extra cuts and sewings on this area. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Eb94VA5jhpE.html Leather is more resistant to stretching. Leather is like vinyl, it has a stretchy side too: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-dhmCJFpOs_0.html To improve the stretching it would be necessary the application of a leather softener: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-r1X3sSjfgw4.html If we stretch leather to its maximum, we immediately feel we cannot stretch it anymore...it has a limit. No much probabilites to tearing up with our hand force. The disadvantage with leather is it stretches less than vinyl and if it has embossed grain it it erased off. Heat can be applied on vinyl to improve the stretching. Heat is applied on leather to erase some wrinkles or creases. It does not increase the stretching. It shrinks instead.

@@Cechaflo clear brother Cech… thank you for responding.. Also, do you have a pdf file we can purchase to learn leatherwork? Like a full tutorial guide we can buy online, as we are located abroad (DUBAI).. I am happy to make a PayPal payment to you if you can provide one.. I love leather, but it’s too difficult to find a specialist here to learn from.. god bless ♥️..

@@H-2-O ✅Any donation to support the channel will be much appreciated! Paypal : cechaflo@gmail.com ✅Get our courses at: www.cechaflo.com Regarding the PDF it would be pretty interesting to prepare a leaflet full of information about leather material for automotive purposes. What are the best leathers? , Wfhere to get it?, How to restore it, etc. Some information in the meantime: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-wPw7SixQb7o.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-mUJFkCCqFYM.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-lRb1CJeSLyE.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-dhmCJFpOs_0.html

Unfortunately, most of the vinyls become brittle and crack after a few years of use. I am in Mexico, but I have found a good link to get automotive vinyls: www.albrightssupply.com/automotive-vinyls

@@Cechaflo Wow thank you Mr. Cechaflo for that link. I will look at that website. I've noticed that expensive vinyl chairs will have a type of vinyl that is thick, soft, and quite nice to feel, almost as nice as a good upholstery leather. Also, thank you so much for making these incredible videos for us to follow along and add value to our own vehicles and other things. I've learned a lot from your excellent videos and true craftsmanship. You are a real artisan, and generous for putting all of these techniques RU-vid. Hey here's a question for you, if you have a minute: What is the toughest possible leather or vinyl that you would use if you were going to do a commercial vehicle, (semi truck)? What material is the most durable?

The UV sun rays, humidity, and other malignant agents make the vinyls dry with the consequences you know. I think the best vinyl is a 'marine vinyl' which was manufactured to endure daily exposure to sun rays and sea salt. www.albrightssupply.com/products-search?qs=marine+vinyl The toughest leather is the one used for automotive purposes (2 to 3 coats of transparent sealer(lacquer) on top to make it more durable and resistant to UV sun rays. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-wPw7SixQb7o.html apexleather.com/fusion/

@@Cechaflo Awesome! Thank you for the tips Mr. Cechaflo! I will keep this in mind.

Estimado amigo, el pegamento que usé en este video es el FR-128 Glumex/Euroforte www.casadelpegamento.mx/ También utilizo el Plastigon. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-TIKF6NvXHE4.html Estos pegamentos de poliuretano son para zapatos y tennis. En Cd de México: facebook.com/ArrowMexico/ arrowdemexico.com/ Hay muchas marcas y en realidad no uso uno exclusivo. El pegamento lo venden en las tiendas de artículos y productos para los zapateros.

Muchas gracias por su tiempo y la informacion tocante las pegaduras. Estoy seguro que le va ayudar a muchos con la misma pregunta. Siga adelante mi amigo con sus trabajos maravillosos. Gracias.

I suppose you are referring to the glue. I am located in Mexico and trademarks are different. In the first anchored comment of this video there is a list of different similar polyurethane glues. You would need to do your own research and tests in order to find a good one that suits your requirements. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-TIKF6NvXHE4.html

@@Cechaflo oh great. and is that real leather or something else?

The title of the video says ' how to stretch vinyl'. There is a different process for leather.

@@Cechaflo oh so its vinyl that looks like leather. do you have a link for it?

@@Cristopher.C I used a 2 way stretch automotive vinyl: www.albrightssupply.com/automotive-vinyls A 4 way stretch vinyl would work out muvh better: www.albrightssupply.com/sample-of-allsport-4-way-stretch-vinyl-aztec-red-smas110

Is it a hat?

He has shown this before. IIIRC, it’s not used as an adhesive but as a “softener” of sorts.

Before stretching the vinyl piece the pasted coats of polyurethane glue should be thoroughly dry. It dries in 10 minutes, but it could remain from one day to another with no problem. The glue should be activated with the heat once the piece is stretched and shaped,

@@Cechaflo Could you please tell me what brand of heat activated polyurethane glue you are using. I am in Canada and after doing a number of searches the only form of polyurethane glue that keeps coming up is Gorilla glue which is water activated but nothing that specifically says heat activated.

@@oh8wingman In the first anchored comment there is a list of similar products. You would needl to search for until finding the required product. Do not forget the key is these glues are used in the shoemaking industry. I source this glue from local stores here in Mexico. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-TIKF6NvXHE4.html

Polyester thread 92 size for blind closing sewings. Same size for top stitches. Occasionally, 138 thread size.

@@Cechaflo I am asking sir just if I want to stitch french seams on leather only with no backing.

@@paramdhillon7074 It is matter of taste. A 138 polyester thread size with a 140=22 needle size for french stitches. No problem if no backing in case of dashboards, consoles, etc. For the seats it is advisable the use of a backing cloth on the reverse.

Ok sounds good whenI try french seams with no backing the stitches do not come up tight and neat. What could be the reason. Also vinyl or leather makes any difference to the quality of stitches

And what needle to use with 92 thread?

@@Cechaflo thanks you sir🙋‍♂️

It is only a demonstration of a technique to stretch and shape a 2 way-stretch automotive vinyl. Besides to keep it with the desired shape. I used this technique on this videos:ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Eb94VA5jhpE.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-cKl5si8naDs.html

@@Cechaflo Yes it does work very well in the video. No wrinkles. Very little opportunities or reasons to use a sheet of wood to form something for an automobile though .

En este video en el primer comentario fijado hay uan lista de productos parecidos que son de poliuretano y activados con calor. Tendría que investigar por uno parecido con marca igual o diferente en el lugar donde radica. La clave es aue se usa mucho en la fabricación del zapato y tenis.ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-TIKF6NvXHE4.html

In real upholstery it is not necessary to deal with too bulky or hollow pieces. I have used the technique on this car console: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Eb94VA5jhpE.html
