1. Will future patches adhere to the new coating?

The best way to apply a new patch after your boat has been renewed with Tuff-Coat is to sand off the topcoat and apply patch to the material under it - it doesn't matter if you sand jus to the basecoat or right down to the original material - either way the patch will adhere if it is properly applied.

2. Can it be applied in the winter?

Yes but temperature must stay above freezing and drying times will be much longer the colder it gets. 

3. Can it be spread with a regular paint brush?

Tuff-Coat can be brushed, rolled or sprayed.

4. Do you paint over the rubber strips?

<p>For the best finish any rubber strips should be cleaned with Xylene and then taped off.</p>

5. Does TUFF-COAT Crack or peel?

<p>Tuff-Coat will not crack or peel (within tested temperature and environmental conditions) providing it has been applied to a properly prepared surface.</p>

6. How do I apply Tuff-Coat?

<p><strong>BASECOAT</strong><br /> 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. Boats may need to have a mechanical bond with the basecoat and require a scuffing with a 3M pad or equivalent prior to application. After surface is cleaned, dried, prepared and repaired, begin application of Basecoat.</p>

<p>Stir well.&nbsp; Coat worn and problem areas first. Deflate boat until flaccid. Allow to fully dry. (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.&nbsp; Proceed to topcoat application</p>

<p><strong><strong>TOPCOAT</strong><br /> </strong>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,&nbsp; Allow 3-4 hours for topcoat to dry before applying second coat (if required). SRC Topcoat cleans up with warm soapy water. <strong><br /></strong></p>

7. How heavily do you apply it?

<p>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.</p>

8. How long should it take to do a 9 foot Inflatable?

<p>Like anything else it depends on a number of factors. Proper preparation is critical for any coating and Tuff-Coat is no different. The boat needs to be clean and free from any contaminants (like oil or Armorall) I recommend rubbing down the surface with a 3m pad prior to application of the basecoat. Once the boat has been prepped application of basecoat should take about two hours.</p>

<p>The 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.</p>

9. Is it applied to all surfaces of the inflatable including the bottom?

<p>It may be applied to all surfaces made from PVC or Hypalon. it is not recommended to apply Tuff-Coat to the fiberglass bottom of a&nbsp; RIB.</p>

10. Is Mixing Necessary?

<p>Tuff-Coat 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 and the reason we can do this is because since it will be coated with Tuff-Coat Topcoat we don't have to worry about how sticky it is.</p>

<p>If it was not to be top coated it would stick to itself when the inflatable was rolled up. The topcoat is a liquid vinyl that is formulated to bond with and actually vulcanize to the basecoat.</p>

11. Must it be evenly spread?

<p>For a good looking job the basecoat should be thinned with Tuff-Coat thinner or a high quality Xylene. The consistency should be like light cream or tomato soup.</p>

12. What about PVC Boats?

<p><strong><strong>PVC</strong><br />&nbsp;</strong>Tuff-Coat works quite well on PVC but it requires an additional step&nbsp; for a satisfactory restoration. There are two main difference in applying&nbsp; Tuff-Coat to PVC (rather than hypalon) First 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.</p>

<p>The second difference is that you must wait longer for the&nbsp; Tuff-Coat to cure. This could be as much as a week.&nbsp; With Hypalon the basecoat dries upwards and downwards while with PVC the Xylene carrier must vent upwards only.</p>

<p>Topcoat will apply the same as on a hypalon boat.</p>

13. What about Worn Areas?

<p><strong>WORN AREAS </strong><br />Hypalon base coat 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 coating coating the worn area first with a coat of SRC Basecoat and then before it dries coat&nbsp; a piece of canvas with SRC Basecoat and apply it to the worn area, recoat the patch with Basecoat once it is in place. Make sure the hypalon base coat is dry (not tacky) it may take anywhere from 12 hrs to 4 or 5 days depending on temperature and humidity. Then apply finish coat .</p>

14. What is the Coverage?

<p><strong><strong>COVERAGE</strong><br /> </strong>Coverage is 40-60 sq ft per quart for hypalon base coat and 60-80 for topcoat. You need one Quart Kit (Contains one qt. Basecoat and one qt. Topcoat) to do an eight foot dingy.</p>
