hi i want to use this product GacoPro Roof Coating on a metal corrugated roof 5 metres x 5 metres ? will this product seal the overlaps be able to cover flash band and cope with expansion and shrinkage of the metal , would one coat be sufficient many thanks |
Answer from Rawlins’ Technical Team:
Assuming the metal roof is bare metal, it is clean, dry, sound and prepared as detailed in the technical data sheet and primed with GacoFlex E5320 2-Part Epoxy Primer/Filler it can be used. Overlaps could be sealed with Gaco Liquid Roof Tape prior to application, then two coats of GacoPro Roof Coating should be applied. this is solar reflective so should aid with reducing thermal contraction and expansion, it is also remains flexible in varying temperatures. | |
| John Taylor on 2021-05-11 16:39:28 | Question:
I Have a felt roof which is painted over with reflecting paint. would this Gaco Pro paint cover this surface .the area is 150 sq feet how much do I require to cover this area. Thanks |
Answer from Rawlins’ Technical Team:
This paint can be applied directly to many substrates and existing roof coatings, we would recommend testing for compatibility and adhesion prior to full applicaton on the painted roof. Assuming this goes well, the roof is clean, dry. sound and prepared as detailed in the technical data sheet this could be used. For 2 coats of 150ft² you will require approximately 11.5ltr. | |
| Paul S on 2021-03-09 18:35:31 | Question:
Are seagulls likely to damage the painted surface on a flat roof? We live by the sea and seagulls are often on the roof. |
Answer from Rawlins’ Technical Team:
Assuming the coating is applied correctly as detailed in the Technical Data Sheet seagulls walking on the roof should be fine. | |

| Neil on 2019-10-09 07:40:43 | Question:
Hi I need to address blowback under tiles for a shallow pitch shed roof. Considering stripping back the tiles and forming a draining 'box' section under the roof from additional vertical battens and drainage gaps in horizontal battens and then covering roof and battens with Gaco before reinstating tiles giving a waterproof under roof as well. Will Gaco go over the underlying roof (strand board or ply) with batten to roof seams sealed with roof tape successfully? Any primer needed and would liquid or fixed roof tape be needed? |
Answer from Rawlins’ Technical Team:
GacoPro Roof Coating can be applied to plywood directly but we recommend 3 coats are applied instead of the usual 2. | |

Hi is this available in the uk and if so are there any stockists in or around maidstone Kent .I see from your write up this product is suitable for covering old grp flat roofs once the old flacking paint has been scrapped off and the roof cleaned, then the product should stick to the old surface with out the use of a primmer is that correct ?

| DAVID on 2018-06-12 21:24:12 | Question: I have a fiberglass roof about 22 years old. Should I start thinking about replacing roof or should I paint it with solar reflective paint? Thanks Dave |
Answer from Rawlins’ Technical Team: We can't advise on whether you need to replace your roof or not, you would need to refer to a local roofer for advice on that. However if the roof is found to be OK then GacoPro Roof Coating would be an excellent way of extending the life. | |
| James sails on 2018-02-17 20:49:02 | Question: Hi, you state that the white can reflect 85% of the sun's rays but can you tell me what the grey will reflect. Thanks. |
Answer from Rawlins’ Technical Team: We do not have any reflectivity factors for the grey, but the darker the colour, the more heat it will absorb which means that grey would be a lot better than black felt etc, but the white would ultimately be the most reflective. | |
| james on 2017-05-23 14:11:45 | Question: Can it be used:
