SOME COMMON ISSUES WITH THIS TYPE OF STRUCTURE INCLUDE;\n•\tLOOSE FIXINGS AND FASTENERS\n•\tCUT END CORROSION OF METAL SHEETS\n•\tMISSING PROFILE FILLER PIECES - RIDGE AND EAVES\n•\tLEAKING GUTTERS\nFIXINGS\nFIXINGS ARE CONSIDEREDTHE MAIN REASON FOR WATER INGRESS IN THIS ROOF. ALLOWING WATER INGRESS. FIXINGS WILL ALSO BE AFFECTED BY RUST AND WILL PROVE DIFFICULT TO TIGHTEN UP. ALL THE FIXINGS SHOULD BE WIRE BRUSHED AND GIVEN INDIVIDUAL TREATMENT IN ACCORDANCE WITH THE COATING MANUFACTURER'S SPECIFICATION.\nTHE NUMBER OF FIXINGS SHOULD ALSO BE CHECKED. FOR ADEQUATACY \nTHE WORK SHALL INCLUDE THE SUPPLY AND INSTALLATION OF THE KEMPEROL LIQUID APPLIED WATERPROOFING SYSTEM TO THE EXISTING METAL PITCH ROOF, AS WELL AS THE LINING OF THE GUTTERS.\nALL WORK SHALL BE CARRIED OUT IN ACCORDANCE WITH THE MANUFACTURER'S GUIDELINES AND BRITISH STANDARDS FOR ROOFING SYSTEMS.\n2.

SURFACE PREPARATION\nEXISTING METAL ROOF SURFACE SHALL BE CLEANED, DEGREASED, AND FREE FROM DUST, RUST, OIL, AND LOOSE DEBRIS.ANY STRUCTURAL REPAIRS, INCLUDING MINOR RUST TREATMENT OR SEALING HOLES, SHALL BE COMPLETED PRIOR.\nTHE METAL SURFACE MUST BE DRY AND PRIMED WITH THE RECOMMENDED KEMPEROL METAL PRIMER, APPLIED IN ACCORDANCE WITH THE MANUFACTURER'S INSTRUCTIONS.\n4. PRIMER APPLICATION \nAPPLICATION SHOULD ONLY TAKE PLACE WHEN THE AIR TEMPERATURE IS +5°C OR GREATER AND THE SUBSTRATE IS +3°C (AND RISING) ABOVE THE DEW POINT.\nINSPECT THE SURFACE TO BE COATED TO ENSURE IT IS DRY AND FREE FROM CONTAMINATION. APPLY BY BRUSH OR NYLON ROLLER TO SEAL AND CONDITION THE SUBSTRATE\n5.WATERPROOFING APPLICATION\nAPPROXIMATELY 2/3 OF THE REQUIRED KEMPEROL® RESIN SHOULD BE APPLIED TO THE PRIMED SUBSTRATE PRIOR TO EMBEDDING THE KEMPEROL® FLEECE. ROLL OUT THE KEMPEROL® FLEECE DIRECTLY INTO THE LIQUID KEMPEROL® WATERPROOFING SYSTEM ENSURING THERE ARE NO FOLDS, CREASES OR AIR BUBBLES, ALLOWING FOR 50MM ON FLEECE OVERLAPS. USE A ROLLER OR BRUSH TO REMOVE ANY AIR BUBBLES AND THEN APPLY THE REMAINING APPROXIMATELY 1/3 OF THE KEMPEROL® WATERPROOFING RESIN WHILE THE FIRST COAT IS STILL WET UNTIL THE FLEECE IS FULLY SATURATED. AVOID ACCUMULATIONS OF MATERIAL.\nALL OVERLAPS IN THE FLEECE SHOULD BE FULLY SATURATED TO ENSURE CONTINUITY OF THE SYSTEM AND BE A MINIMUM OF50MM.

CURING AND PROTECTION\nALLOW THE KEMPEROL SYSTEM TO CURE FULLY AS PER MANUFACTURER GUIDELINES BEFORE ANY FOOT TRAFFIC OR EXPOSURE TO WATER.\nENSURE THE SURFACE IS PROTECTED FROM MECHANICAL DAMAGE DURING AND AFTER APPLICATION.\n8. GUARANTEE\nTHE KEMPEROL SYSTEM SHOULD BE GUARANTEED FOR A MINIMUM OF 20 YEARS AGAINST WATER INGRESS, PROVIDED ALL INSTALLATION STEPS ARE FOLLOWED.\n9.

GUARANTEE\nTHE COMPLETED KEMPEROL WATERPROOFING INSTALLATION SHALL BE ELIGIBLE FOR A MANUFACTURER-BACKED GUARANTEE, SUBJECT TO INSTALLATION BY AN APPROVED CONTRACTOR AND COMPLIANCE WITH THE MANUFACTURER'S SPECIFICATION.\nPROJECT SPECIFICATION: UPPER LEVEL MASONRY REMEDIALS\n1. SCOPE OF WORK\nTHE WORKS COMPRISE THE LOCALIZED REPOINTING AND BRICK REPLACEMENT TO THE HIGH-LEVEL PARAPET, PEDIMENT, AND ASSOCIATED TRIANGULAR AND HORIZONTAL GABLES. THIS INCLUDES:\nCAREFUL REMOVAL OF FAILED OR NON-BREATHABLE (CEMENTITIOUS) MORTAR.\nREPLACEMENT OF PERISHED OR \"BLOWN\" BRICKS TO MATCH THE EXISTING BOND AND CHARACTER.\nAPPLICATION OF NEW LIME-BASED MORTAR TO THE HIGH-LEVEL ELEVATIONS.\n2. MATERIALS AND MATCHING\nBRICKS: ANY REPLACEMENT UNITS MUST MATCH THE EXISTING IN DIMENSIONS, COLOR, TEXTURE, AND COMPRESSIVE STRENGTH. GIVEN THE \"PERISHED\" NATURE MENTIONED, RECLAIMED OR HANDMADE BRICKS SHOULD BE SOURCED TO ENSURE A SEAMLESS BLEND WITH THE 19TH-CENTURY FABRIC.\nMORTAR MIX: A NATURAL HYDRAULIC LIME (NHL 3.5) MIX IS RECOMMENDED TO ALLOW FOR MOISTURE MOVEMENT AND BREATHABILITY.\nRATIO: TYPICALLY 1:2.5 OR 1:3 (LIME:AGGREGATE).\nAGGREGATE: WELL-GRADED SHARP SAND, COLOR-MATCHED TO THE EXISTING WEATHERED JOINTS.\nSAMPLES: A 1M² SAMPLE AREA OF REPOINTING AND A SAMPLE OF REPLACEMENT BRICKS MUST BE APPROVED ON-SITE BEFORE FULL COMMENCEMENT.\n3. PREPARATION AND EXECUTION\nRAKING OUT: JOINTS MUST BE RAKED OUT MANUALLY OR USING SPECIALIZED OSCILLATING TOOLS TO A MINIMUM DEPTH OF 20MM (OR TWICE THE JOINT WIDTH). STRICTLY NO USE OF ANGLE GRINDERS, WHICH RISK DAMAGING THE BRICK ARRISES.\nCLEANING: JOINTS MUST BE BRUSHED CLEAN AND PRE-WETTED WITH DEIONIZED WATER TO PREVENT THE MASONRY FROM \"SUCKING\" MOISTURE OUT OF THE NEW MORTAR TOO QUICKLY.\nLAYING & POINTING: * NEW BRICKS MUST BE LAID TO MATCH THE EXISTING FLEMISH OR ENGLISH BOND (AS APPLICABLE TO THE SPECIFIC SECTION).\nMORTAR SHOULD BE FIRMLY \"IRONED\" INTO THE JOINTS.\nFINISH: A \"RECESSED\" OR \"FLUSH\" FINISH (TO BE CONFIRMED BY SAMPLE) THAT IS LIGHTLY BRUSHED BACK AS IT REACHES ITS INITIAL SET TO EXPOSE THE AGGREGATE AND AVOID A \"FATTY\" LIME FINISH.",
