The best way to apply a new patch after your boat has been renewed with TUFF SRC is to sand off the Topcoat and apply your patch to the material under it - it doesn't matter if you sand just to the basecoat or right down to the original material - either way the patch will adhere if it is properly applied.
Yes but the temperature must stay above freezing and drying times will be much longer the colder it gets.
TUFF SRC can be brushed, rolled or sprayed.
No. For the best finish, any rubber strips should be cleaned with Xylene and then taped off.
TUFF SRC will not crack or peel (within tested temperature and environmental conditions) providing it has been applied to a properly prepared surface.
Surface preparation must provide a clean dry material free from mildew, oil, wax or grease. Leaks other than pinhole size must be repaired prior to application. If mildew is present wash boat thoroughly with a solution of one part household bleach and three parts soapy water. PVC Boats may need to have a mechanical bond with the TUFF SRC Basecoat and require a scuffing with a 3M pad or equivalent prior to application. After tube surface is cleaned, dried, prepared and repaired, begin application of TUFF SRC Basecoat.</p>
Stir well. Paint any worn and problem areas first. Deflate boat until flaccid. Allow to fully dry for 24hrs minimum). Fully inflate and test for missed pinhole leaks. Rinse, dry and repeat application to any problem areas. Allow 24 hrs for any problem areas to dry, then paint a complete coat over entire tube surface area. Cleanup is with Water. Proceed to TUFF SRC Topcoat application.
Surface must be clean and dry as well as free from wax, grease, oil, and mildew before application. Do not apply outside if rain is forecast within 12 hours. Stir well. Allow 3-4 hours for Topcoat to dry before applying a second coat (if required). TUFF SRC Topcoat cleans up with warm soapy water.
On severely damaged areas - like where the fabric is threadbare - up to three coats may be applied to restore the integrity of the material. On areas where there is less or little damage, one coat should suffice.
Like anything else, it depends on a number of factors. Proper preparation is critical for any coating and TUFF SRC is no different. Major tears and holes need to be repaired before applying TUFF SRC.
The boat needs to be clean and free from any contaminants (like oil or Armorall). We recommend rubbing down the surface with a 3M pad prior to application of Basecoat. Once the boat has been prepped, application of Basecoat should take about two hours.
TUFF SRC Basecoat needs to dry thoroughly before applying Topcoat. There should be no strong chemical (xylene venting) smell when Topcoat is applied. Again a couple of hours should do it.
It may be applied to all surfaces made from PVC or Hypalon.
Do not apply Tuff-Coat to
- fiberglass bottom of a RIB
- the rub rails or valve covers
- the rubber step plates (found on some inflatables)
TUFF SRC comes in two parts but they are not mixed. They are applied separately. The Basecoat or undercoat is a specially blended synthetic rubber. It is formulated very aggressively for adhesion to the native tube material AND to bond strongly to the Topcoat.
If the Basecoat did not have Topcoat applied, it would stick to itself - when deflated or rolled up (for non-RIB boats). The TUFF SRC Topcoat is a liquid vinyl that is formulated to bond with and actually vulcanize to the TUFF SRC Basecoat.
For a good looking job, Basecoat should be thinned with a high-quality Xylene. The consistency should be like light cream or tomato soup.
TUFF SRDC works quite well on PVC but it requires an additional for a satisfactory restoration. There are two main differences when applying TUFF SRC to PVC (rather than Hypalon).
- A mechanical bond must be created with a light sanding or scuffing of the surface with a 3M pad or equivalent before application of the Basecoat.
- You must wait longer for the Basecoat to cure. This could be as much as a week. With Hypalon, the Basecoat dries upwards and downwards while with PVC the Xylene carrier must vent upwards only.
Topcoat will apply to PVC the same as on a Hypalon boat.
On Hypalon, Basecoat should be applied to high wear areas first and recoated if needed prior to Topcoat being applied.
If the area is really worn a patch can be applied by first painting the worn area with a coat of TUFF SRC Basecoat and then before it dries coat a piece of canvas with TUFF SRC Basecoat and apply it to the worn area. Recoat the patch with Basecoat once it is in place.
Make sure the Hypalon Basecoat is dry (not tacky). This may take anywhere from 12 hrs to 4 or 5 days depending on temperature and humidity. Then apply the finish TUFF SRC Topcoat .
Coverage is 40-60 sq ft per quart for TUFF SRC Basecoat and 60-80 sq ft per quart for TUFF SRC Topcoat.
For example, you will need one Quart Kit (Contains one qt. Basecoat and one qt. Topcoat) to restore an eight-foot dingy.
