There are 3 types of sealant, Silicone based, Polyurethane based and Acrylic based. The best one to use for caulking windows or exterior work are medium modulus silicone based sealants, something like Dow Corning 791-N weather sealant. It will last a lifetime, does not crack, harden, discolour or be affected by UV degradation or UK temperature variation. Its whats used in high rise buildings. For most single part sealants, there is a use by date... so when you buy sealant, make sure you check if there is a use by date. Silicone sealant past the use by date do not cure properly. These are generally more expensive, but if applied properly, will never have issues with them for 30+ years. Anything that is translucent is not a silicone sealant, more likely acrylic based, these will turn yellow after 6 months, harden and crack thereby ruining any seal.... my 2 cents for the day. Thanks for your videos!... very entertaining.
@@Dobame I don't, I am an exterior cladding guy. But if your shower tray is plastic, i.e. the seal has to cater for a bit of movement from loading and or expansion from different material and temperature, I would go with a polyurethane or silicone based sealant, medium modulus. You will inevitably get mould on it at some stage, so a sealant that says anti-mould would suffice. You could just use a black sealant so you never see the mould 😂. Check out the use by date. Eitherway, you'll be recaulking it every few years. UK house construction sucks!

Hello,多謝你嘅有用分享🙏🏻想請教下如果我需要填補返啲bricks 嘅罅隙，請問用邊類物資填補返比較好同耐用，因為我車房頂有啲bricks見到有罅，亦都有滲水入車房內面天花位置，所以想補返睇吓有冇用🙏🏻🙏🏻🙏🏻同埋我個flat roof 嘅felt 有啲位置吾平，所以落雨後就會有個水氹仔，可以用啲咩嘢整返平嗰地面？🙏🏻🙏🏻🙏🏻thank you
你好，多謝收睇。 brick隙用 mortar。 flat roof 嘅felt 你指室外嗎？ 謝謝
@@backtotheuk 首先多謝你嘅回覆呀🙏🏻brick隙用mortar 可唔可以用好似玻璃膠包裝嗰種？flat roof 嘅黑色felt係室外，因為我見到室內天花嘅環保夾板有滲水，所以想睇吓可唔可以自己DIY 補返🙏🏻我上網搵到有啲係油roof嘅roof seal coating ，含有bitumen-based 吾知道啱唔啱🙏🏻thank you
@@maggieli399 可以，但會唔同色，建議用返mortar. 個roof 你試下買支膠叫 roof and gutter sealant black
@@backtotheuk 🙏🏻等我買咗試吓先😊
@@maggieli399 要先知道roof係咩位漏，是否裂痕或是其他問題先可以個知道下步點做。
睇唔清牌子，可以寫低牌子及用途嗎？謝謝
同問😂
可唔可以寫低牌子? Tks
請教如何更換浴缸邊及洗手盆邊的玻璃膠？
將舊膠除去再打新。
請問通常要多久才乾透 ，可以使用 .
每種膠都有唔同嘅乾時間，膠背面有寫大約幾耐乾。
支膠用左一半，請問用咩野封口，可以保持耐d？
有啲膠會跟個蓋，如果無可以用保鮮紙包住只要唔入空氣就會減少膠頭嘅膠變硬。
請問牆和天花之間有裂痕，用甚麼膠
通常會批盪，要睇下點裂法。
請問用唔晒點樣可以keep住下次可以再用？多謝分享！
膠咀位置用保鮮紙包住或蓋封好。多謝收睇。
@@backtotheuk 我試吓，因為次次我都唔可以用得返！
@@ahsuk2275以我多年做DIY 的經驗、玻璃膠如果一次不能用完成枝玻璃膠、可以用任何膠紙any kind of tape ,封住口、然後用膠嘴擰實、待下次再用時應該冇問題！希望可以解答你的問題！
