Please note the following postcodes are classed as Non-Mainland UK or Remote / Rural delivery: AB, IV, KW, PA, PH, HS, KA, ZE, PO30-PO41, IM, JE, GY, BT, TR21-TR25. All surfaces must be dry and dust free before using Everbuild Puraflex 40. All flaking or loose surface coatings and any old sealants should be removed before application. In addition to that, when using on glass, metal and aluminium, areas should be cleaned with a proprietary solvent cleaner before application for optimum adhesion. When using Everbuild Puraflex 40 with solvents, always ensure adequate ventilation. Avoid heat, sparks and open flames. Observe and follow all precautions listed on the solvent container label. It is not recommended for application to surfaces that are below 5˚C as it is impossible to guarantee a dry, frost-free surface at these temperatures. Therefore the sealant will most likely fail. It is unlikely that priming will be required; however, concrete must be sealed using a Primer. After that, if you are in doubt, consult Technical Services. PRIMER Hi Rich, If you are using aluminium frames then essentially the sealant will only need to be used to create a gasket. There is my opinion is no need to have a good adhesion if the window is held tight by rivets or bolts and a frame. Aquaseal mSEAL has been known to work well for this purpose and Geocel Marine Rubber Silicone is something I have personally used with good results. It is said that silicone is an inert synthetic polymer compound and is technically part of the rubber family. You can imagine why its been a favourite in boat maintenance for some time. Its UV resistant, heat resistant, a great insulator and is ideal for creating gaskets. Its downfall is that it makes for a weak adhesive and for this reason sometimes is unpractical for use below the water line. Compatibility - will it work with your material you wish to bond it too? Will it be safe for below the waterline?

It looked great for a few weeks but then the planks dried and swelled etc and it popped the sealant. The sealant wasn't to blame here, the problem was there was a great deal of water getting in through the topsides of the boat. Delamination, leaky fittings and windows resulted in water pouring on the inside of the hull like a waterfall. As the boat was out of the water the planks were dry on the outside and taking a hammering of UV but wet on the inside. The new owner renewed the caulking, dropped it in the water and the problem seems to have been solved. I have since borrowed and cruised it and noticed no water ingress now that planks have swollen. So to summarise, imagine you're an evil man wanting to pull someones' arms off using horses. Tensile strength is the amount of horse's you would need to pull them off which is measured in N/mm2 or MPa. The elongation break is how long the poor persons' arms will stretch before they rip off - ouch! Remove all of the sealant taking care not to damage the glass or frames, using a sharp knife. Tape the window and frames up using frog tape or blue painters tape then apply the sealant in even smooth beads.

Tensile Strength - the resistance of a material to breaking under tension. To put it even clearer this is the amount of force a material can take until it breaks apart. This is measured in N/mm2 to MPa and can normally be found on a product datasheet. A favourite amongst boating enthusiasts CT1 is suitable as a universal adhesive and will work in all applications. CT1 has no shrinkage and can be applied in both damp and wet conditions. It adheres to most metals (including lead) as well as glass, mirrors, wood, polystyrene and GRP. Water - visibly dripping through into your cabin during rainy days. Leaking water can often be seen forming small droplets on the bottom of protruding bolt heads. Wait for a forecast of rain or cheat and use a hose to find leaks. If you get your bilge bone dry beforehand, you'll be able to follow the trails of water from any leaky hardware by looking at your bilge areas with a hand torch. This method works amazingly well. If you have a dirty bilge it seems to be even easier and the trail seems to show up clearer where the dirt is wet. A non-adhesive sealant will generally rely on the aid of a fitting, screw or bolt to create a waterproof seal. With a normal sealant, you are essentially creating a waterproof gasket. You can't rely on normal sealant to hold anything in place; you are relying on a method of fastening, for example; a screw or bolt. Types Of Sealant is all around one part polyurethane adhesive sealant that can be used to bond wood, gel coat and fibreglass. It can also be used above and below the waterline.

This product is recommended for sealing and bonding metal panels and trim. Expansion joint sealing in conrete panels, floor joint, road and bridge construction. Sealing in applications subject to vibration and mechanical abrasion. Marine applications provides resistance to salt water multitude of sealing and bonding applications in the automotive and engineering markets. Bonding in container fabrication. If it was me i’d probably get a coded welder patch the hole and have a designated skin fitting with shutoff valve for the inlet.

I’m trying to visualise the issue, the swaging makes it a little more difficult. I’m not entirely, sure how any tube simply put through and hole will have a good seal. For a gasket to work you really need tension pushing outwards from the ID to seal. rubber changes over time, due to the elements and exposure. aluminium, polyester, glass, uPVC, stone, ceramics and more. Use Puraflex 40 in sealing and bonding applications subject Resistant to fresh water, seawater, limewater, sewage effluent, diluted acids and caustic solutions; temporarily resistant to fuels, mineral oils, vegetable and animal fats and oils.

Primer is not always essential unless using on porous surfaces like concrete. If primer is needed, use Sika 3N Primer LIMITATIONS UniBond FlexTec FT101 is a one component hybrid polymer which can be used to seal, fill and bond. It claims to be able to bond without the use of a primer to a wide range of materials but doesn't specify which ones it does not. It can also be applied on both damp and wet surfaces but does take 24hours to set and may not ideal for fast same day repairs.Here is the link to the datasheet for Aquaseal – http://www.everbuild.co.uk/image/data/Tech%20Sealants/mSEAL%20595%20Tech%20Datasheet%20Rev.%202.pdf

Sealants were originally designed to patch holes in planes during the war but since then they've got a lot more complicated. Corporate competition means companies are continuously trying to outdo each other. The marine industry is constantly screaming out for products that last longer and perform better and subsequently, we are fed increasingly better sealants. A lot of companies who create sealants eventually wise up to the fact that their product will work in the 'marine' industry, and often subtly add it to their datasheet without it being a specific marine product and liable for leisure tax. We've even created a beautiful acronym for you to remember: 'SFCSS' (pronounced; Suu-Fuu-Cissss). See, if that's not catchy enough for you then I don't know what is!
