Apply a 3mm (1/8″) layer of plastic cement for dry or wet surfaces, the CR25, to the joint around the chimney. Place reinforcing mesh in the plastic cement and cover it with another 3mm (1/8″) layer of plastic cement for dry or wet surfaces. The product will follow temperature changes will not crack because the mesh serves as a reinforcement.

The most frequent places are in the valleys’ around the chimneys’ at the end of the sloping roofs and around the fans or ventilation system.

Apply CR2030 clear coating to the old roof area, in which you can add a latex stain to match the color of the new roof.

Use CR25 plastic cement for dry or wet surfaces in small quantities, i.e. 1 inch diameter 3mm (1/8″) thick. Then, nail the shingle or staple it.

​

Use CR40 Black Fibered Roof Coating by applying a 3mm (1/8″) thin coat. It is a product that remains on the surface, because it is made with fiber. It gives a thicker protective layer than the non-fibered coating. It can extend the roof's use by 2 to 3 years if applied in several thin coats during the same application and if it has time to dry well. A rubberized fibered coating CR340 can also be used in the same way. This product is rubberized. We also have a range of siliconized products for roofs: Roofseal. These products are latex-based and come in several colours.

Warning: if the product is applied in too thick a layer, it will only dry on the surface and if it rains, the product could fade or turn yellow.

Using clear roof plaster CR2030 helps to keep the granules in place on the shingle and prevents them from falling into the slabs. The fungicide it contains avoids black marks or fungal growth on the north side, as is frequently seen. It is a latex product that is applied to a dry shingle. Make sure there will be no rain for 24 to 48 hours after application as rain will completely wash the product away.

Use Sealflex, a colored and rubberized product with elastomer that restores color to the shingle. If the shingle has several shades, it will become a solid color. The elastomer contained in Sealflex protects the pores of the shingle and prevents water infiltration. There are 2 types of products: Sealflex is applied on a wooden, metal or shingle roof. The formulation of Roofseal, on the other hand, does not include an anti-corrosion product. It is applied on all roofs except metal roofs. Several colors are available including: green, brown, grey, concrete grey, black, white, brick red and beige.

Use Sealflex or Roofseal, colored and rubberized products with elastomer that restore color to the shingle. If the shingle has several shades, it will become a solid color. The elastomer contained in Sealflex protects the pores of the shingle and prevents water infiltration. There are 2 types of products: Sealflex is applied on a wooden, metal or shingle roof. The formulation of Roofseal, on the other hand, does not include an anti-corrosion product. It is applied on all roofs except metal ones. Several colors are available including: green, brown, grey, concrete grey, black, white, brick red and beige.

The elastomers contained in the coatings CR340, CR380 or CR390, or in Sealflex and Roofseal, make them rubberized by giving them a certain elasticity and sealing micro cracks, which makes them much more effective than a regular coating. It is also more resistant to temperature variations and is specially designed for flat or metal roofs.

These coatings are waterproof, durable and designed to resist UV rays, cracks, peeling, chalking, mold, and discoloration. Sealflex is applied on wood, metal, shingles and concrete. The Roofseal can be applied to all surfaces except metal.

Be sure to close the windows, the air exchanger, the air conditioning and the ventilation units. The roof must be dry and dust-free. Check that there will be no rain for 24 to 48 hours after application to allow the product to dry properly.

There are 2 possible solutions. The first one is to completely change the roof. The second one is a temporary solution. You have to pierce the bubble and cut it crosswise. Then, wipe off the water or moisture on the roof (dry well). Then, apply to the roof, inside the bubble, a thin layer of plastic cement CR25. It is preferable to wait until the plastic cement is dry, but not mandatory, before closing the bubble by attaching the sides. Finally, apply a thin layer of CR25 plastic cement to the surface of the bubble. Apply a reinforcing mesh to the CR25 layer and apply another thin layer of plastic cement on top. Plastic cement layers should not exceed 3mm (1/8″) as it otherwise will dry on the surface and crack during the first few days after application. The operation will therefore have to be restarted.

Always repair from the outside. A repair from the inside will be useless. You will have to dig where the crack is and clean the foundation with pressure. Once the foundation is dry, apply CR360 Rubberized Foundation Coating or CR340 Fibered Rubberized Coating if you need a thicker membrane (strongly recommended on a block foundation). If this has not already been done, it is advisable to apply plastic cement at the junction of the foundation and the footing.

The best way to repair a crack is to cover it with CR20 or CR25 plastic cement, add reinforcing mesh and cover it with another layer of plastic cement. In order to unify the appearance of the foundation, it is suggested to cover the entire surface with a CR60 foundation coating.

A non-fibered bitumen-based roof coating can be used as a replacement for foundation coating. The non-fibered coating is thicker than foundation coating. However, foundation coating cannot be used on a roof.

CR340 fibered rubberized coating is strongly recommended on a block foundation, as the fibres will give a thicker protection. CR360 rubberized foundation coating can also be used. However, it is also possible to apply a Sealflex elastomeric coating. Sealflex gives a strong coloured protective layer on the foundation. Available colors: green, grey, brown, concrete grey, black, white, brick red and beige.

Sealflex elastomer coating is waterproof, durable and specially designed to resist cracks, peeling, chalking, mold and discoloration. Sealflex contains an anti-corrosion agent that prevents and reduces the formation of rust on old metal substrates. It is available in several colors: green, grey, brown, concrete grey, black, white, brick red and beige.

The Sealflex and Force 1 rustproofs are quality products made of oil, oxidation-resistant additives and/or bitumen. They are designed to resist and fight rust.

All of our rustproofs are slightly scented, they smell like fruits.

None of our rustproofs drip or leak if they are applied in a thin layer. Various thin layers are preferable to a thick layer.

The Sealflex Black and Sealflex Amber are annual products, which means they must be applied every year.

All vehicle surfaces must be clean, dry and free of rust flakes.

On fiberglass and polymer: the oil contained in the rustproof will migrate to the surface and create oil stains. In the long run, the oil can peel the paint. Warning: nothing can repair this damage.

On rubber: for a light drizzle, it’s not serious. If it is overexposed to the product‚ it will become soft and lose its elastic properties.

You can ask a clerk who can make a special order. Delivery times are fast, and in a few days the product can be delivered.

Use baby oil or lighter fluid to carefully clean the stain. Caution: a trace of colour may remain on the surface.
