Sem Sure-Coat --- note that this is a waterborne product --- dries a couple shades darker and looks a little different if spraying or brushing + number of coats. 

If you are spraying, especially with an airbrush, it is recommended to add some sure-coat reducer to thin the colorant for maximum atomization.

Directions for Sem Sure-Coat recoloring of leather: clean with Sem plastic/leather prep --- spray over leather liberally and scrub with gray pad and wipe dry with lint free cloth. add Sem crosslinker (increases adhesion and aids resistance to general household cleaners)  to recolorant according to directions on bottle. spray or brush in light coats.  If brushing, use foam brush and do not be in a hurry to achieve coverage.  Let dry in between coats.  If spraying, spray in light mist coats, again not being in a hurry for coverage.  Have adequate ventilation (fan is good) to dry completely between coats. If you do not have spray equipment, check out the economical power pak sprayer (good for sure-coat).  (refer to recommended reducer mentioned above)

Directions for Sem Sure-Coat recoloring of vinyl: clean first with Sem Soap----squeeze a bead onto area; spray some water and scrub with green pad; wipe dry with lint free cloth. clean second with Sem WB vinyl prep----spray liberally over area; scrub with green pad; wipe dry with lint free cloth.  Sem recommends rinsing with water now.   Sem surface cleaner #3838 can also be used as a substitute cleaner for this step. Pour your chosen color of sure-coat into the container you will be working from.  Add Sem crosslinker according to directions and shake up well. 

Apply same as directions in leather recoloring above.          GOOD LUCK!!!!!!   

EXTRA TIPS:If you are just recoloring some hard plastic pieces, prior to recoloring you can prep the area with Sem aerosol plastic adhesion promoter or XXX adhesion promoter for all surfaces.  If you want more grain or texture on the dashboard or hard plastic pieces, spray on the aerosol Sem texture coating.  If you are just recoloring your dashboard, an optional prep to spray on prior to recoloring with Sem color coat is the Sem aerosol Sand Free product.  Do not use Sand Free with Sem sure-coat. 

All of this is not difficult work and you can definitely achieve a professional result.

Classic Coat by SEM for vinyl or leather only!!!! Use the same cleaners and preps mentioned above depending if you are spraying vinyl or leather.  Since these are aerosols, there is, of course, no crosslinker additive or reducer.   Not for hard plastics.

vinyl repair detailed step-by-step directions


Simple step by step directions without the pictures---read carefully and you should be able to completely understand these so you can do a great vinyl repair.

Supplies needed:  SEM soap, SEM waterborne vinyl prep, green cleaning pad, graining material, pointed and trowel knives, aycrosol, colored vinyl compound, strip palette, backing fabric, chemscreen, teflon, heat gun with reducing cone &/or “fixer tool,”™ &/or special 100W rewelding iron, cold block &/or hard yellow plastic, airbrush or foam brush, SEM colorants.

Vinyl repair on newer material or non-abrasive areas.

  1. plug in heat tools.
  2. clean with sem soap followed by sem waterborne vinyl prep.
  3. make graining mold from a well-defined grain.
  4. insert backing fabric shiny side up and heat around outer edges of cut and lightly press with cold metal block, provided cut is all the way thru.
  5. apply thin layer of aycrosol or colored compound over repair area.
  6. cure out completely with heat gun or “fixer”™tool.  (shiny, dull, shiny)
  7. repeat step number six 4-6 times to make repair area level, even mounding a little in center.
  8. on last heating application, apply graining mold by pressing down immediately after heating with cold block or yellow hard plastic.  If slightly mounded in center, grain will cut in a little better most times.
  9. airbrush or foam brush color in light coats to blend with surrounding area.

Vinyl repair on older materials or abrasive areas.

Same as above except prior to step #5, cut chemscreen a little large than repair area.  Apply a thin layer of aycrosol over and out beyond repair area, place chemscreen over same area and apply a little more aycrosol, making sure the edges of the chemscreen are wet.  Place the piece of teflon over entire repair area and iron with “fixer”™tool or larger 100W iron.  Do not apply pressure and keep the iron moving.  Place cold block over for a few seconds, and then peel teflon back just a little to see if aycrosol is cured out.  If aycrosol is not completely cured out, place teflon back down and continue ironing.  After this step is completed, apply one or two more layers of aycrosol, curing out each layer and proceed from step 8 above.
